ECH was used as the internal standard(IS) to obtain the relative correction factors(RCFs) of the other four phenylethanoid glycosides(PhGs);meanwhile, various influencing factors on RCFs were investigated under different conditions. The content of each component was calculated with RCF. The results were compared with those obtained by the external standard method(ESM) to verify the feasibility and accuracy of the established QAMS method. No significant difference was found in the quantitative results of 10 batches of Cistanches Herba between QAMS and ESM. The proposed QAMS method for simultaneous determination of PhGs in Cistanches Herba is accurate and feasible, providing an efficient and economical approach for the quality control of Cistanches Herba.展开更多

METHODS： Forty-eight BALB/c mice were random-ly divided into two groups in the ratio of I ： 3, 12 in one group and 36 in the other. The 12-mouse group was the control group that was intragastrical- ly administered physiological saline for 3 weeks. The 36 mice in the other group were given 30 mg- kg ·^-1 d i GRT for 3 weeks, then randomly divided into 3 subgroups： the model group, GRI group and Roucongrong （Herba Cistanches Deserticolae） group, with 12 mice in each group. In the model group, 0.25 mL physiological saline was intragastri- cally administered; in the GRT group, GRT, 0.25 mL at 30 mg · kg ^-1· d ^-1 was intragastrically adminis- tered once a day; in the Roucongrong （Herba Cis- tanches Deserticolae） group, mice were adminis- tered Roucongrong （Herba Cistanches Deserticolae） decoction equivalent to 0.25 mL at a final dose of 10g.kg 1.d.1 crude drug （calculated as per 20 times of 0.5 g· kg^-1. d ^-1 for adults）, and GRT 0.25 mL at 30 mg- kg^-1· d^- 1 daily. After another 3 weeks of exposure, expression levels of the reproduction-re- lated genes DEAD （Asp-Glu-Ala-Asp） box polypep- tide 3, Y-linked, B-cell CLL/lymphoma 6 and Signal transducer and activator of transcription 3 were evaluated. RESULTS： After 6 weeks of GRT treatment, the sper- matogenic cell population in the convoluted tu- bule of testis was in disorder and the tubule cavity expanded. Sertoli cell and Leydig cells exhibited at- rophy or disappeared. The number of sperm de- creased. The spermatogenic cell level of testis for male mice was ranked in order and sperm was pro- duced in the cavity of the spermatogenic cell. The expression levels of DDX3Y, BCL6 and STAT3 were up-regulated.CONCLUSION： GRT affected reproduction-related genes. Roucongrong （Herba Cistanches Desertico- lae） reversed reproductive toxicity in mice induced by GRT.展开更多

Beck, which belong to Orobanchaceae family, include about twenty species, and there are four species and one variety are distributed in the northwest part of China. The dried fleshy stem of Cistanche genus plant known as ＇Roucongrong＇ in Chinese traditional medicine, has long been used for kidney deficiency, female infertility, morbid leucorrhea, and neurasthenia. Studies on active components and pharmacological activities show that it possesses significant activities in enhancing potency, anti-fatigue, immuno-modulability, etc, and phenylethanoid glycosides are the major active components. Due to excessive exploitation, its natural resources are facing with exhaustion. In order to improve this situation, the plant has been cultivated on a large scale in the northwest part of China. Up to now, the chemical investigations of the cultivated Cistartcbe salsa have not been undertaken. In this paper we report seven phenylethanoid glycosides from the cultivated Cistanche salsa： echinacoside （1）, cistanoside A （2）, acteoside （3）, isoacteoside （4）, 2＇-acetylacteoside （5）, tubuloside B （6）, and eutigoside A （7）. Among them, compound 7 isolated fronl family Orobanchaceae was reported previously, and compounds 1, 2, 3, 4, 5 and 6 from the cultivated Cistanche salsa are reported for the first time.展开更多

Methods Samples containing natural products and thrombin at various ratios were incubated at 25 ℃ and then were separated by CZE with Tris-acetate buffer at pH 7.2. Each run could be accomplished within 5 min. Results In CZE, the peak width broadened due to the affinity interaction between natural products and thrombin. Compared with positive and negative control, the natural products （CB-1, CB-2） from Coreopsis tinctoria Nuttt. interacted with thrombin; CB-3 from Coreopsis tinctoria Nuttt. and HC-1, HC-2, HC-3 from Cistanche deserticola Ma. did not bind to thrombin. Both qualification and quantification characterizations of the binding were determined. Conclusion The established method is capable of sensitive and fast determination of natural products and thrombin interactions, it can be employed as an alternative method.展开更多

Due to excessive exploitation, its natural resources are facing with exhaustion. In order to improve this situation, the plant has been cultivated on a large scale in the northwest part of China. Up to now, the chemical investigations of the cultivated Cistartcbe salsa have not been undertaken. In this paper we report seven phenylethanoid glycosides from the cultivated Cistanche salsa： echinacoside （1）, cistanoside A （2）, acteoside （3）, isoacteoside （4）, 2＇-acetylacteoside （5）, tubuloside B （6）, and eutigoside A （7）. Among them, compound 7 isolated fronl family Orobanchaceae was reported previously, and compounds 1, 2, 3, 4, 5 and 6 from the cultivated Cistanche salsa are reported for the first time.
文摘Aim A capillary zone electrophoretic method （CZE） was used to determine the interactions between natural products and thrombin. Methods Samples containing natural products and thrombin at various ratios were incubated at 25 ℃ and then were separated by CZE with Tris-acetate buffer at pH 7.2. Each run could be accomplished within 5 min. Results In CZE, the peak width broadened due to the affinity interaction between natural products and thrombin. Compared with positive and negative control, the natural products （CB-1, CB-2） from Coreopsis tinctoria Nuttt. interacted with thrombin; CB-3 from Coreopsis tinctoria Nuttt. and HC-1, HC-2, HC-3 from Cistanche deserticola Ma. did not bind to thrombin. Both qualification and quantification characterizations of the binding were determined. Conclusion The established method is capable of sensitive and fast determination of natural products and thrombin interactions, it can be employed as an alternative method.
