Pakistan suffers from a lack of fresh water supplies;hence most people use metal-containing water and wastewater to irrigate their crops. Exposure to Cr toxicity, the plant reduces their morphological and physiological growth which ultimately decreases crop productivity. The current study was designed to investigate the foliar application of hesperidin (HSP) at varying effluent rates (25, 50, 75, and 100 mg L^(−1)) on wheat growth under tannery wastewater irrigated soil. Cr toxicity caused a change in the concentration of chlorophyll molecules, indicating early signs of stress. Modifications in the ultrastructure of chloroplasts, the elevated activity of chlorophyllase, and the generation of reactive oxygen species were causing the reduction in chlorophyll. Cr stress disrupted total soluble protein concentrations and the activity of antioxidation-related enzymes and NRA, suggesting the onset of oxidative stress. On the other hand, the application of HSP reduced oxidative damage by improving protein concentration (37%), chlorophyll concentration (37%), and antioxidant enzyme activity such as CAT (65%), SOD (46%), and POD (68%). Furthermore, HSP raised the concentrations of non-enzymatic antioxidant molecules, which may indicate better redox homeostasis and stress tolerance. These molecules include GSH, GSSG, ascorbic acid, flavonoids, phenolics, and anthocyanins. HSP therapy lessened the impact of Cr stress on lipid peroxidation markers. HSP enhanced these measures during the investigation. Cr stress raised the concentrations of total free amino acids and nitrogen oxide and decreased the radical scavenging activity in wheat. Cr stress raised the concentration of all soluble sugars, primarily reducing and non-reducing sugars, whereas the application of HSP strengthened these osmo protectants even more results of the present investigation indicate that exogenous HSP is a feasible and eco-friendly approach to improving plant resistance against Cr toxicity by efficiently reducing the physiological strain and metabolic stress caused by Cr in wheat plants.展开更多

However, its protective effects on bovine mammary epithelial cells(b MECs) exposed to oxidative stress have not been elucidated.Results In this study, we investigated the effects of hesperidin on H_(2)O_(2)-induced oxidative stress in b MECs and the underlying molecular mechanism. We found that hesperidin attenuated H_(2)O_(2)-induced cell damage by reducing reactive oxygen species(ROS) and malondialdehyde(MDA) levels, increasing catalase(CAT) activity, and improving cell proliferation and mitochondrial membrane potential. Moreover, hesperidin activated the Keap1/Nrf2/ARE signaling pathway by inducing the nuclear translocation of Nrf2 and the expression of its downstream genes NQO1 and HO-1, which are antioxidant enzymes involved in ROS scavenging and cellular redox balance. The protective effects of hesperidin were blocked by the Nrf2 inhibitor ML385, indicating that they were Nrf2 dependent.Conclusions Our results suggest that hesperidin could protect b MECs from oxidative stress injury by activating the Nrf2 signaling pathway, suggesting that hesperidin as a natural antioxidant has positive potential as a feed additive or plant drug to promote the health benefits of bovine mammary.展开更多

It is an effective antioxidant and free radical scavenger that has anti-inflammatory, antiviral and hypoglycemic properties.The latest studies reported that hesperidin has a potential for novel coronavirus resistance. However, little is known about the synthesis regulation and accumulation site of hesperidin in plants. In this study, hesperidin synthase gene Crc1,6RhaT was cloned, and the protein can be completely transformed flavanone-7-O-glucoside into hesperidin in vitro and in vivo. Studies on biological characteristics of ovary walls and exocarps showed that the relative expression levels of the Crc1,6RhaT gene and protein decreased gradually with the development of citrus fruits, and the relative content of hesperidin firstly increased, then sequentially decreased. In situ hybridization results further revealed that Crc1,6RhaT transcription was mainly concentrated in the secretory cavity cells, which are revealed to be the site of flavonoid synthesis.Immunocytochemistry localization results showed that the Crc1,6RhaT was mainly located in the endoplasmic reticulum, nucleus and vacuole of secretory cells. We inferred that the Crc1,6RhaT was synthesized in the endoplasmic reticulum, then was transported into the vacuoles through enlarged vesicles at the end of the endoplasmic reticulum. Our results not only revealed that Crc1,6RhaT may be involved in the synthesis of hesperidin of the main bioactive substance in the medicinal plant Citrus reticulata ‘Chachi' fruit, but also provided novel insights into the main subcellular sites of hesperidin biosynthesis in vacuoles.展开更多

Our previous studies confirmed that flavonoids, including hesperidin, naringin and nobiletin, inhibited thrombogenesis and hypertension in stroke prone spontaneously hypertensive rats (SHRSP) by protecting the endothelium from the adverse effects of free radical formation. We have now further investigated the protective effects of myricetin and hesperidin on cerebral thrombosis and atherogenesis in apolipoprotein E (apoE) and lowdensity lipoprotein receptor (LDLR) deficient (Apoe-/- and Ldlr-/- double knockout) mice. Three groups of mice were fed high fat diet alone and high fat diet mixed with myricetin (100 mg/kg/day and 200 mg/kg/day) or glucosyl hesperidin (G-hesperidin;250 mg/kg/day and 500 mg/kg/day) for 8 weeks. There were no differences in body weight related to administration of the flavonoids. Thrombotic tendency was assessed using a He-Ne laser technique in the murine cerebral pial vessels. In addition, atherogenesis was quantified histologically after dissection of the aorta from each mouse and staining with Oil Red O solution. The percentages of stained area to whole area of dissected aorta were calculated as indices of anti-atherogenic activity. Both myricetin and G-hesperidin significantly inhibited thrombogenesis in vivo and significantly inhibited atherogenesis compared to control mice (p < 0.001). These findings demonstrated that daily intake of myricetin and hesperidin suppressed the development of atherogenesis and thrombogenesis, possibly associated with the potent antioxidant effects of the flavonoids.展开更多

The aim of this work was to evaluate hesperidin antimutagenicity against cisptatin-DNA damage. （1） The antimutagenicity of hesperidin was assayed by bone marrow of mice in vivo using the micronucleus test. Hesperidin pre-treatment protocol reduced the frequency of MNPCE （micronucleated polychromatic erythrocytes） and the dose of 100 mg·kg-1 was highest efficiency, with 65.24% of damage reduction. In the simultaneous treatment protocol, the dose of 200 mg·kg-1 exhibited a more effective reduction of MNPCE, with 94.01% of damage reduction. （2） Hesperidin was also effective in reducing the MNPCE frequency in the post-treatment protocol for all doses, with 77.48%, 82.13% and 90.08% of damage reduction at the doses of 100, 200 and 400 mg·kg-1, respectively. From the study, it can be concluded that hesperidin was able to promote the reduction of micronuclei frequency and DNA damage induced by cisplatin. Hesperidin is a powerful antioxidant compound and its chemoprotective effects on DNA may occur due to its association with the antioxidant cell system which is responsible for eliminate free radicals generated by chemical harmful to DNA.展开更多

Several studies have indicated that pesticide toxicity may be associated with the enhanced production of ROS （reactive oxygen species）. Both β-carotene （I3C） and hesperidin （H） have an antioxidant property and quench free radicals. This study aimed to clarify the protective role of β-carotene and hesperidin as natural antioxidants on IM induced toxicity in hematological parameters and markers of cardiac muscle activity in male albino rats. The treatment of rats with IM showed a significant decrease in hemoglobin （Hb %）, MCH （mean corpuscular hemoglobin）, MCHC （mean corpuscular hemoglobin concentration）, HCT （hematocrit） values and RBCs count comparing with control group. On the other hand, MCV （mean corpuscular volume）, WBCs （white blood cells） and Pits （platelets） count pronounced a significant increase in IM group comparing to control. Also, αFP （plasma alpha fetoprotein）, CEA （carcinoembryonic antigen）, CK （creatine kinase）, CK-MB （creatine phosphokinase myocardial band） and LDH （lactate dehydrogenase） clarify a significant increase in IM group comparing to control. Both β-carotene and hesperidin mitigate the deleterious effects of IM on previous parameters. β-Carotene and hesperidin may protect hematopoietic system and heart muscle against toxicity of IM. These improvements of the results clarify the protective effect of the used antioxidants. Conclusion： β-carotene and hesperidin, natural antioxidants, have a protective effect against IM evoked hematological and biochemical changes.展开更多

文摘Chemotherapy-induced toxicity(CIT)remains a major concern in cancer patients undergoing chemotherapy.New approaches to ameliorate the side effects of chemotherapy are urgently needed.Recently,the nutritional value of citrus fruits has attracted wide attention.Hesperidin and its aglycone hesperetin are the main active components in citrus fruits.Hesperidin and hesperetin have a wide range of pharmacological activities,including antioxidant and anti-inflammatory properties.This review aims to provide insights into the potential application of citrus flavonoids in CIT and summarize the underlying mechanisms of hesperidin and hesperetin in alleviating CIT.We have collected and collated relevant scientific articles on hesperidin and hesperetin and their treatment of CIT from different scientific databases.Hesperidin and its glycosides can reduce the toxicity of chemotherapeutic drugs,and their therapeutic effects are mainly through anti-inflammatory and antioxidant effects.At present,modern medical treatment is the main treatment method for CIT,but hesperidin,as an extract of food and medicinal materials,can greatly alleviate CIT.While killing tumor cells,chemotherapeutic drugs also damage normal cells leading to toxic effect on various organs.The pathological mechanism of CIT has not been fully elucidated,but current evidences indicate that cellular stress plays a key role.The citrus flavonoids hesperidin and hesperetin have the protective effect against CIT,highlighting its potential as an adjuvant in chemotherapy regimens.Hesperidin may also have synergistic anti-tumor activity with chemotherapeutic agents.We believe that more functional foods and anti-CIT drugs based on natural foods will be developed.

文摘Encapsulation and protection of hesperidin(HES)in mung bean protein isolate(MPI)-dextran(DX)conjugatestabilized nanoemulsions(MDC NEs)were investigated in this study.The degree of grafting of MDC prepared by a dry-heating method reached 39.70%±0.01% under the optimal conditions of MPI/DX mass ratio 1:2.3,reaction temperature 58.8℃,and reaction time 4 d.Moreover,the analyses of Fourier infrared spectroscopy,intrinsic fluorescence spectroscopy,surface hydrophobicity,and thermal stability further confirmed the covalent grafting of dextran onto MPI molecules.When encapsulated in MDC NEs at 80 MPa for three times by highpressure homogenization,the encapsulation efficiency and loading capacity of HES were 63.62%±0.01%and 0.40±0.00 g/g,respectively.The encapsulated HES exhibited higher antioxidant activity and stronger light and storage stability than the free HES.Additionally,the incorporation of HES inhibited the formation of lipid peroxides in the nanoemulsions.The findings suggest that glycosylation combined with high-pressure homogenization is an effective strategy for enhancing the stability of MPI-based emulsions and improving their encapsulation of HES.This study provides a promising approach for the development of innovative food and beverage products based on MPI emulsions or new materials for encapsulating fat-soluble bioactive compounds.

文摘Chromium (Cr), a persistent soil pollutant, has detrimental effects on plants and living things, and its contamination in soil increased as a result of human-induced activities. Pakistan suffers from a lack of fresh water supplies;hence most people use metal-containing water and wastewater to irrigate their crops. Exposure to Cr toxicity, the plant reduces their morphological and physiological growth which ultimately decreases crop productivity. The current study was designed to investigate the foliar application of hesperidin (HSP) at varying effluent rates (25, 50, 75, and 100 mg L^(−1)) on wheat growth under tannery wastewater irrigated soil. Cr toxicity caused a change in the concentration of chlorophyll molecules, indicating early signs of stress. Modifications in the ultrastructure of chloroplasts, the elevated activity of chlorophyllase, and the generation of reactive oxygen species were causing the reduction in chlorophyll. Cr stress disrupted total soluble protein concentrations and the activity of antioxidation-related enzymes and NRA, suggesting the onset of oxidative stress. On the other hand, the application of HSP reduced oxidative damage by improving protein concentration (37%), chlorophyll concentration (37%), and antioxidant enzyme activity such as CAT (65%), SOD (46%), and POD (68%). Furthermore, HSP raised the concentrations of non-enzymatic antioxidant molecules, which may indicate better redox homeostasis and stress tolerance. These molecules include GSH, GSSG, ascorbic acid, flavonoids, phenolics, and anthocyanins. HSP therapy lessened the impact of Cr stress on lipid peroxidation markers. HSP enhanced these measures during the investigation. Cr stress raised the concentrations of total free amino acids and nitrogen oxide and decreased the radical scavenging activity in wheat. Cr stress raised the concentration of all soluble sugars, primarily reducing and non-reducing sugars, whereas the application of HSP strengthened these osmo protectants even more results of the present investigation indicate that exogenous HSP is a feasible and eco-friendly approach to improving plant resistance against Cr toxicity by efficiently reducing the physiological strain and metabolic stress caused by Cr in wheat plants.

文摘Ulcerative colitis(UC)is a chronic inflammatory disorder with a complex etiology,characterized by intestinal inflammation and barrier dysfunction.Platycodon grandiflorus polysaccharides(PGP),the primary component of Platycodon grandiflorus,and hesperidin(Hesp),a prominent active component in Citrus aurantium L.(CAL),have both demonstrated anti-inflammatory properties.This study aims to elucidate the underlying mechanism of the synergistic effect of PGP combined with Hesp on UC,focusing on the coordinated interaction between the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)and Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3)signaling pathways.A mouse model of UC induced by dextran sulfate sodium(DSS)and a cell model using lipopolysaccharide(LPS)-induced RAW264.7/IEC6 cells were employed to investigate the in vitro and in vivo anti-inflammatory effects of PGP combined with Hesp on UC and its potential mechanism of action.The results indicated that compared to the effects of either drug alone,the combination of PGP and Hesp significantly modulated inflammatory factor levels,inhibited oxidative stress,regulated colonic mucosal immunity,suppressed apoptosis,and restored intestinal barrier function in vitro and in vivo.Further in vitro studies revealed that PGP significantly inhibited the PI3K/AKT signaling pathway,while Hesp significantly inhibited the JAK2/STAT3 signaling pathway.The use of inhibitors and activators targeting both pathways validated the synergistic effects of PGP combined with Hesp on the PI3K/AKT and JAK2/STAT3 signaling pathways.These findings suggest that PGP combined with Hesp exhibits a synergistic effect on DSS-induced colitis,potentially mediated through the phosphatase and tensin homolog(PTEN)/PI3K/AKT and interleukin-6(IL-6)/JAK2/STAT3 signaling pathways.

文摘Background Hesperidin is a citrus flavonoid with anti-inflammatory and antioxidant potential. However, its protective effects on bovine mammary epithelial cells(b MECs) exposed to oxidative stress have not been elucidated.Results In this study, we investigated the effects of hesperidin on H_(2)O_(2)-induced oxidative stress in b MECs and the underlying molecular mechanism. We found that hesperidin attenuated H_(2)O_(2)-induced cell damage by reducing reactive oxygen species(ROS) and malondialdehyde(MDA) levels, increasing catalase(CAT) activity, and improving cell proliferation and mitochondrial membrane potential. Moreover, hesperidin activated the Keap1/Nrf2/ARE signaling pathway by inducing the nuclear translocation of Nrf2 and the expression of its downstream genes NQO1 and HO-1, which are antioxidant enzymes involved in ROS scavenging and cellular redox balance. The protective effects of hesperidin were blocked by the Nrf2 inhibitor ML385, indicating that they were Nrf2 dependent.Conclusions Our results suggest that hesperidin could protect b MECs from oxidative stress injury by activating the Nrf2 signaling pathway, suggesting that hesperidin as a natural antioxidant has positive potential as a feed additive or plant drug to promote the health benefits of bovine mammary.

文摘Hesperidin is a dihydroflavonoids, accounting for more than 50% of the total flavonoids in Citri Reticulatae Pericarpium(CRP) of traditional Chinese medicine. It is an effective antioxidant and free radical scavenger that has anti-inflammatory, antiviral and hypoglycemic properties.The latest studies reported that hesperidin has a potential for novel coronavirus resistance. However, little is known about the synthesis regulation and accumulation site of hesperidin in plants. In this study, hesperidin synthase gene Crc1,6RhaT was cloned, and the protein can be completely transformed flavanone-7-O-glucoside into hesperidin in vitro and in vivo. Studies on biological characteristics of ovary walls and exocarps showed that the relative expression levels of the Crc1,6RhaT gene and protein decreased gradually with the development of citrus fruits, and the relative content of hesperidin firstly increased, then sequentially decreased. In situ hybridization results further revealed that Crc1,6RhaT transcription was mainly concentrated in the secretory cavity cells, which are revealed to be the site of flavonoid synthesis.Immunocytochemistry localization results showed that the Crc1,6RhaT was mainly located in the endoplasmic reticulum, nucleus and vacuole of secretory cells. We inferred that the Crc1,6RhaT was synthesized in the endoplasmic reticulum, then was transported into the vacuoles through enlarged vesicles at the end of the endoplasmic reticulum. Our results not only revealed that Crc1,6RhaT may be involved in the synthesis of hesperidin of the main bioactive substance in the medicinal plant Citrus reticulata ‘Chachi' fruit, but also provided novel insights into the main subcellular sites of hesperidin biosynthesis in vacuoles.

文摘Objective:To explore the cardioprotective effect of hesperidin against arsenic trioxide-induced cardiac toxicity in rats.Methods:Cardiac toxicity was induced by oral administration of 4 mg/kg arsenic trioxide for 30 days.Hematological,biochemical,electrocardiography,echocardiography,and histopathological examinations were performed.Results:Hesperidin decreased the neutrophil-to-lymphocyte ratio,calcium,creatine kinase-myoglobin binding,lactate dehydrogenase,IL-6,and lipid peroxidation,as well as increased sodium and potassium concentration and superoxide dismutase and catalase activity in arsenic trioxide-intoxicated rats.Moreover,it reduced peak systolic velocity and end-diastolic velocity while increasing heart rate.Arsenic trioxide-induced histopathological damage to cardiac tissue was prominently alleviated by hesperidin treatment.Conclusions:Hesperidin attenuates arsenic trioxide-induced cardiac toxicity in rats.Therefore,it can be further explored as a cardioprotective agent.
文摘Flavonoids have been reported to possess strong antioxidant activities that moderate endothelial dysfunction and demonstrate protective effects on cardiovascular disease. Our previous studies confirmed that flavonoids, including hesperidin, naringin and nobiletin, inhibited thrombogenesis and hypertension in stroke prone spontaneously hypertensive rats (SHRSP) by protecting the endothelium from the adverse effects of free radical formation. We have now further investigated the protective effects of myricetin and hesperidin on cerebral thrombosis and atherogenesis in apolipoprotein E (apoE) and lowdensity lipoprotein receptor (LDLR) deficient (Apoe-/- and Ldlr-/- double knockout) mice. Three groups of mice were fed high fat diet alone and high fat diet mixed with myricetin (100 mg/kg/day and 200 mg/kg/day) or glucosyl hesperidin (G-hesperidin;250 mg/kg/day and 500 mg/kg/day) for 8 weeks. There were no differences in body weight related to administration of the flavonoids. Thrombotic tendency was assessed using a He-Ne laser technique in the murine cerebral pial vessels. In addition, atherogenesis was quantified histologically after dissection of the aorta from each mouse and staining with Oil Red O solution. The percentages of stained area to whole area of dissected aorta were calculated as indices of anti-atherogenic activity. Both myricetin and G-hesperidin significantly inhibited thrombogenesis in vivo and significantly inhibited atherogenesis compared to control mice (p < 0.001). These findings demonstrated that daily intake of myricetin and hesperidin suppressed the development of atherogenesis and thrombogenesis, possibly associated with the potent antioxidant effects of the flavonoids.

文摘<strong>Introduction: </strong>There are extensive people exposures to paraquat (PQ) herbicide resulting in human health hazards. <strong>Aim of the Work:</strong> To compare the beneficial neuroprotective effects of hesperidin and benfotiamine on paraquat (PQ)-induced spinal cord neurotoxic effects in rats. <strong>Materials and Methods:</strong> Rats were divided into 4 groups as following: control, paraquat (PQ 20.8 mg/kg, oral gavage (e.g.)), paraquat + benfotiamine (50 mg/kg, oral gavage (e.g.)) and paraquat + hesperidin (40 mg/kg, oral gavage (e.g.)). PQ is given as the previous dose. Rats are treated 6 days per week.<strong> Results: </strong>There was a significant increased mean value of malondialdehyde associated with a significant reduction in the content of reduced glutathione and antioxidant enzymes activities associated with a significant increase in Serum phosphorylated neurofilament-H, neurospecific enolase and s100 levels were recorded and significant spinal cord histopathological changes in paraquat treated group as compared to their corresponding values in the control group and immunohistochemical examination confirmed these results. Upon supplementation with benfotiamine and hesperidin to paraquat treated rats, there was a significant decrease in the mean values of malondialdehyde associated with a marked increase in the content of reduced glutathione and antioxidant enzymes activities associated with a significant decrease in Serum phosphorylated neurofilament-H, neurospecific enolase and s100 levels were also recorded with significant improvement of spinal cord architecture when compared with the paraquat treated group. <strong>Conclusion:</strong> The use of benfotiamine and hesperidin produced a significant protection against all of the above-mentioned changes.
文摘Hesperidin is a bioflavonoid abundantly found in citrus fruits and displays chemoprotective effects against DNA （deoxyribonucleic acid） damage, however there are few reports about hesperidin effects against cisplatin-DNA damage induction. The aim of this work was to evaluate hesperidin antimutagenicity against cisptatin-DNA damage. （1） The antimutagenicity of hesperidin was assayed by bone marrow of mice in vivo using the micronucleus test. Hesperidin pre-treatment protocol reduced the frequency of MNPCE （micronucleated polychromatic erythrocytes） and the dose of 100 mg·kg-1 was highest efficiency, with 65.24% of damage reduction. In the simultaneous treatment protocol, the dose of 200 mg·kg-1 exhibited a more effective reduction of MNPCE, with 94.01% of damage reduction. （2） Hesperidin was also effective in reducing the MNPCE frequency in the post-treatment protocol for all doses, with 77.48%, 82.13% and 90.08% of damage reduction at the doses of 100, 200 and 400 mg·kg-1, respectively. From the study, it can be concluded that hesperidin was able to promote the reduction of micronuclei frequency and DNA damage induced by cisplatin. Hesperidin is a powerful antioxidant compound and its chemoprotective effects on DNA may occur due to its association with the antioxidant cell system which is responsible for eliminate free radicals generated by chemical harmful to DNA.
文摘Neonicotinoids including IM （Imidacloprid） are widely used as plant systemic insecticides. Several studies have indicated that pesticide toxicity may be associated with the enhanced production of ROS （reactive oxygen species）. Both β-carotene （I3C） and hesperidin （H） have an antioxidant property and quench free radicals. This study aimed to clarify the protective role of β-carotene and hesperidin as natural antioxidants on IM induced toxicity in hematological parameters and markers of cardiac muscle activity in male albino rats. The treatment of rats with IM showed a significant decrease in hemoglobin （Hb %）, MCH （mean corpuscular hemoglobin）, MCHC （mean corpuscular hemoglobin concentration）, HCT （hematocrit） values and RBCs count comparing with control group. On the other hand, MCV （mean corpuscular volume）, WBCs （white blood cells） and Pits （platelets） count pronounced a significant increase in IM group comparing to control. Also, αFP （plasma alpha fetoprotein）, CEA （carcinoembryonic antigen）, CK （creatine kinase）, CK-MB （creatine phosphokinase myocardial band） and LDH （lactate dehydrogenase） clarify a significant increase in IM group comparing to control. Both β-carotene and hesperidin mitigate the deleterious effects of IM on previous parameters. β-Carotene and hesperidin may protect hematopoietic system and heart muscle against toxicity of IM. These improvements of the results clarify the protective effect of the used antioxidants. Conclusion： β-carotene and hesperidin, natural antioxidants, have a protective effect against IM evoked hematological and biochemical changes.
