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

As a famous remedy in China for tonic the kidney, it is used to treat ＂kidney-deficiency syndrome＂-induced diseases such as infertility, forgetfulness, hearing lost, chronic constipation, etc.. As various biological activities, including anti-aging, antioxidant, estrogenic, anti-osteoporotic, and anti- inflammation effects, have been discovered, here we reviewed Cistanches Herba in biological characteristics, chemical constituents, and pharmacological activities.展开更多

文摘利用超高效液相色谱-三重四极杆串联质谱联用法(ultra-high performance liquid chromatography-triple quadrupole mass spectrometry, UPLC-QQQ-MS)比较2种寄主肉苁蓉经过不同干燥处理后的10种苯乙醇苷类成分含量。将肉苁蓉干燥品粉碎,粉末过60目筛,用50%(体积分数)甲醇溶解后超声提取,用Agilent Eclipse Plus C18柱(2.1 mm×150 mm, 1.8μm)分离,以A相(0.1%甲酸水溶液)-B(乙腈)相作为流动相进行梯度洗脱,利用电喷雾离子源,在UPLC-QQQ-MS的动态多反应模式下检测。结果表明,不同干燥处理的寄主肉苁蓉苯乙醇苷类成分含量具有明显差异,冷冻干燥处理所得的肉苁蓉中10种苯乙醇苷类含量最高,其次为80℃烘干样品。虽然冷冻干燥对于肉苁蓉所保留10种苯乙醇苷类成分最高,但基于大规模生产考虑,80℃烘干更具有经济效益。
