Six (6) oil samples were obtained from seeds of three (3) geographical origins. The identification and quantification of fatty acids and the polyphenolic profile were carried out by GC-MS and HPLC-UV, respectively. Analysis of fatty acid methyl esters allowed the identification and quantification of 18 fatty acids. Oils from unwashed seeds were richer in palmitic (C16:0), stearic (C18:0), oleic (C18:1) and arachidic (C20:0) acids. In addition, HPLC-UV analysis at 279 nm shows that oils from unwashed seeds are richer in tyrosol, hydroxytyrosol and caffeic acid. With regard to the polyphenolic profile, gallic acid and quercetin were not detected in these baobab oils. Principal component analysis of fatty acid and phenolic compound content showed that oils from unwashed seeds would best preserve their chemical and associated potential bioactive characteristics.展开更多

文摘Vitamin E is an essential micronutrient that is abundant in peanut seeds.However,the absence of a rapid and reliable method for determining its content has impeded advancements in peanut quality improvement.In this study,we developed an efficient ultra-performance liquid chromatography variable wavelength detector(UPLCvwd)method for quantifying vitamin E content in peanut seeds,capable of detecting four tocopherols and four tocotrienols.Compared to traditional methods,this approach is simpler,more efficient,and highly accurate.By comparing two sample preparation techniques,it was found that slicing better reflects the true vitamin E content than grinding,as it minimizes losses caused by mechanical pressure.The method demonstrated robust stability and accuracy in both repeatability tests and spiked recovery tests,showing no significant differences compared to the national standard method.The study revealed that the cotyledons of peanuts are the primary storage site for vitamin E,being rich inγ-andα-tocopherols,which together account for over 90% of the total vitamin E content.In contrast,the vitamin E content in the seed coat is considerably lower.Therefore,the optimized detection method minimizes seed coat interference during sample preparation,ensuring the accuracy of the results.In summary,the UPLC-vwd method developed in this study is a promising tool for determining vitamin E content and supports the improvement of peanut quality.

文摘Seed to soil contact is critical for successful germination and establishment.The seed coat micromorphology is a stable trait that has contributed significant information to the phylogenetic classification of angiosperms.Seed morphology refers to the physical characteristics of seeds,such as their size,shape,color,texture,and structure.The characteristics can vary greatly among different plant species and can provide important information about the plants'life cycle,ecological requirements,and evolutionary history.The aim of this work was to describe the 34 species representing 23 botanical families that were collected to study the micromorphological features of seeds from Khaplu and Skardu mountainous area.Seed shape,color,and texture were observed under a light and scanning microscope and stereo microscope.Micromorphological and ultrastructural data have proved useful in determining seed plant evolution,classification,ecology,and phylogeny.Seed shapes varied from elliptic,oblong,ovate,pyramidal,and spherical.Surface sculpturing varied from rugulate,negative reticulate,reticulate,foveolate,granular and striated.The seed size varied enormously from very minute Matricaria chamomilla 0.33 mm×0.06 mm to very large seed Elaeagnus angustifolia 13.76 mm×4.70 mm.Epicuticular projections,anticlinal wall,periclinal wall,wall ornamentation,and seed texture were also studied under scanning electron microscopy.Most of the seed colors were brown and black except Carthamus tinctorius which exhibits creamy white color.A principal component analysis was used to identify the most outliers in seed micromorphology and provide a significant explanation.A taxonomic key based on micromorphological features has been constructed to assist botanists in identifying species and genera,and to support the conservation of seed bank resources.
文摘Humans and other vertebrates are safeguarded from invading pathogenic microbes by the immune system.Black seed,scientifically known as Nigella sativa,has garnered attention for its potential immunomodulatory effects in both clinical and preclinical studies.This comprehensive review aims to consolidate and analyze the existing body of evidence surrounding the immunological impact of black seeds.In this review,we analyze the immunomodulatory potentials of black seeds(N.sativa).For the purpose of finding pertinent publications,the literatures was searched in web-based databases,including Web of Science,Medline/PMC/PubMed,Embase,EBSCO,Google Scholar,Science Direct,and reference lists.Several clinical,in vivo,and in vitro studies have demonstrated that supplementation with black seeds(N.sativa)has potential immunomodulatory activity.Black seeds(N.sativa)may influence immune responses through a variety of mechanisms.By synthesizing and critically assessing the current state of knowledge on the immunomodulatory effects of black seeds,this review aims to provide valuable insights into the potential therapeutic uses and future research directions for harnessing the immunological benefits of this natural remedy.

文摘The inflammatory response is a crucial physiological process that can lead to tissue damage and is considered a causative factor for various chronic diseases,such as rheumatoid arthritis.Recent research has focused on exploring valuable nutrients derived from Cannabis sativa L.(hemp)seeds,particularly hemp seed proteins.Therefore,this study aimed to investigate the release of anti-inflammatory peptides from Lactobacillus paraplantarum-fermented hemp seed proteins.To confirm the complete hydrolysis of hemp seed proteins during the fermentation process,sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)was employed.Further,the isolation and purification of peptides were achieved through ultrafiltration.The identity of peptides was nextly established using ultra-high performance liquid chromatography coupled with hybrid quadrupole time-of-flight mass spectrometry(UHPLC-QTOF-MS).The results revealed a total of 39 identified peptides in fermented hemp seeds,with 9 peptides selected based on their relative quantity.Notably,AAELIGVP(P1),AAVPYPQ(P2),VFPEVAP(P4),DVIGVPLG(P6),and PVPKVL(P9)demonstrated strong anti-inflammatory abilities in lipopolysaccharide(LPS)-induced RAW264.7 macrophage cells.Molecular docking was used to understand the potential anti-inflammatory mechanism of these 5 peptides,and in silico results indicated that P1,P2,P4,P6,and P9 could bind to the active sites of toll-like receptor 4(TLR-4),nuclear factor-κB(NF-κB),and inhibitor of NF-κB kinase(IKK)with higher binding energies.Overall,these findings indicate that hemp seeds have potential to be a source of bioactive peptides for functional foods with anti-inflammatory properties.

文摘People living long-term in areas with UV will cause premature photoaging.An abnormal reduction in autophagy is a key feature of photoaging,and p38 MAPK has been regarded as a key regulator of autophagy.Isothiocyanate is one of the main active components of Moringa oleifera Lam.seeds.Studies have reported that M.oleifera Lam.seeds iso thiocyanate(MITC)has anticancer,anti-inflammatory,cardio metabolic repair,nervous system protection,blood lipid regulation and diabetes prevention properties.However,the molecular mechanisms of MITC with protective effects against skin photoaging have not been studied thus far.In this study,we aimed to evaluate the antiphotoaging activity of MITC and to investigate the effect of p38 MAPK-dependent autophagy in vivo and in vitro models of photoaging.In this research we found that MITC can reverse the intracellular reactive oxygen species(ROS)content and inhibit the activation of p38 MAPK to improve the autophagy level,reduce the expression of matrix metalloproteinases(MMPs),and finally protect against photoaging by UV.Our results will uncover the molecular mechanisms of MITC that play a role in the protective effects against skin photoaging,provide helpful information for developing MITC as an anti-photoaging plant material and improve the utilization of M.oleifera Lam.seeds.

文摘Gibberellins(GAs)and auxin play central regulatory roles in seed germination and root system development,respectively,so that the application of these phytohormones to crops would be worthwhile,with an increasing potential demand in agriculture.However,there are few effective chemicals that simultaneously enhance both GA and auxin signaling.Here,we report on an artificial thiourea derivative chemical,Y21,that serves as both a GA-signaling agonist and an auxin analog,promoting seed germination and root development,as well as low-phosphorus tolerance.Phenotypic,biochemical,and genetic evidence demonstrated that Y21 enhances the interaction between GA and its receptor GID1C via the Val239 amino acid residue and consequently promotes degradation of the DELLA proteins REPRESSOR OF ga1-3(RGA)and RGA-LIKE 2.Furthermore,we found that Y21 interacts with the auxin receptor TIR1 via the Cys405 residue and thus promotes the turnover of the auxinresponsive Aux/IAA proteins.Consequently,Y21significantly increases low-phosphorus tolerance of treated plants by positively regulating lateral root development.To our knowledge,Y21 is the first GA-signaling agonist to be identified,and our results also demonstrate that this potent synthetic chemical,identified by chemical genetic screening,is effective at modulating plant development and stress tolerance.

文摘The plant life cycle and the promise of crop yield start with successful seed germination,which requires an optimal balance between the phytohormones abscisic acid(ABA)and gibberellin(GA).Here,we report that the APETALA 2-type transcription factor SALT AND ABA RESPONSE ERF 1(OsSAE1)antagonistically modulates ABA and GA signaling to control seed germination in rice(Oryza sativa L.).We show that knocking out OsSAE1 delays seed germination,concomitant with the accumulation of SLENDER RICE1(OsSLR1),a GA signaling repressor DELLA protein;importantly,GA application rescued the seed germination defect of ossae1 mutants.OsSAE1 directly activates transcription of the GA biosynthesis gene OsKS1 and represses that of the GA metabolism gene OsGA2ox3,resulting in higher GA levels.Moreover,OsSLR1physically interacts with ABA-INSENSITIVE 5(OsABI5),a key ABA signaling component,enhancing the transcriptional activation capacity of OsABI5 toward its target genes to regulate seed germination.The temporal expression pattern of OsSAE1 supports its role in orchestrating GA and ABA signaling to modulate seed germination and seed dormancy.Different OsSAE1 haplotypes differentially affected OsSAE1 transcript levels and seed germination rates,illustrating the potential of the elite OsSAE1 haplotype for genetic improvement of seed germination.Overall,our study reveals that OsSAE1 controls rice seed germination by regulating the balance between ABA and GA,providing a pivotal selection target for breeding rice cultivars suitable for direct seeding.

文摘Seaweed extract contains plant growth regulators and bio-stimulants that enhance plant growth and development.In Bangladesh,winter rice(Boro rice)in the nursery bed often shows poor seed emergence and weak seedling growth due to low temperature.This problem can be addressed by using seaweed extract as a seed priming agent and bio-stimulant.The objective of this study was to evaluate the effectiveness of seaweed extract(Crop Plus)on seed emergence,seedling growth,and vigor of winter rice in the nursery.Two experiments were conducted at Bangladesh Agricultural University using BRRI dhan89.The laboratory experiment consisted of 17 treatments combining three concentrations of Crop Plus(5000,10,000 and 15,000 ppm)and four priming durations(6,12,18,and 24 h),along with hydro-priming and a no priming as control.Seed priming with 15,000 ppm for 24 h produced the highest germination percentage and superior seedling growth traits.The nursery bed experiment comprised 11 treatments combining two doses(1 mL m^(−2)and 2 mL m^(−2))of Crop Plus and five different foliar application schedules,along with a control.All treatments outperformed the control,with the best results from Crop Plus@2 mL m^(−2)applied at 20 and 30 days after sowing(DAS).Overall,the treatment involving seed priming with 15,000 ppm seaweed extract for 24 h,followed by nursery application at 2 mL m^(−2)at 20 and 30 DAS,resulted in higher germination and improved early growth of winter rice.However,further validation across multiple locations,seasons,and rice cultivars is recommended.
文摘Salinity is one of the major abiotic stresses limiting chickpea(Cicer arietinum L.)productivity,particularly in arid and semi-arid regions where soil salinization is intensifying.Developing cost-effective and practical strategies to enhance seedling establishment and early vigor under saline conditions is therefore essential.In this study,we compared two seed-priming agents-1 mM proline and 25 mM NaCl-under identical hydroponic conditions to elucidate tissue-specific responses to 25 mM NaCl stress.Proline priming significantly improved shoot length(by~23%),total chlorophyll content(by~19%),and ascorbate peroxidase(ASPOX)activity.In contrast,NaCl priming enhanced root biomass retention(by~38%)and peroxidase(POD)activity under salinity stress.Both priming treatments induced higher proline accumulation and antioxidant capacity,though with tissue-specific effects:proline favored aboveground resilience,while NaCl strengthened root ionic and oxidative balance.These findings highlight the complementary nature of proline and NaCl priming and support the concept of stress“memory,”whereby plants acquire enhanced readiness to cope with salinity.Integrating such priming strategies into chickpea cultivation could contribute to improved yield stability and sustainability in saline agroecosystems.
文摘Date palm(Phoenix dactylifera L.)seeds,often discarded as by-products during date fruit processing,represent approximately 6-20%of the fruit’s mass depending on cultivar and maturity stage.Although traditionally used for producing activated charcoal and in environmental remediation,their pharmacological potential remains underexplored.This study aimed to evaluate the chemical composition,biological activity,and potential commercial value of seeds from four widely consumed Saharan cultivars(Assiane,Boufegouss,Aziza,and Majhoul)collected in the Figuig region.Soxhlet extraction was employed to obtain seed extracts,which were subsequently characterized by qualitative and quantitative phytochemical screening.The analyses revealed the presence of polyphenols,flavonoids,terpenoids,steroids,alkaloids,and other secondary metabolites.The Aziza and Boufegouss varieties were particularly rich in flavonoids(82.09-139.61 mg quercetin equivalents/100 g dry matter)and total polyphenols(69.81-1183.96 mg gallic acid equivalents/100 g dry matter).Mineral profiling confirmed the occurrence of essential trace elements,including Zn,Cu,Fe,and Co.To investigate their antidiabetic potential,in vitro assays ofα-glucosidase andα-amylase inhibition were performed.Acetone extracts demonstrated significant inhibitory activity against both enzymes,suggesting a promising role of P.dactylifera seed extracts as natural agents for the management of type 2 diabetes mellitus.
