【摘要】 目的:对远志原药材木部及皮部中总皂苷含量进行比较分析,用以指导临床用药。方法:以齐墩果酸为对照品,香草醛-高氯酸为显色剂,采用紫外-可见分光光度法在575nm处测定远志总皂苷含量。结果:以此方法对远志木部及皮部中总皂苷含量进行比较、分析,为远志皮部总皂苷含量为3.33%、木部总皂苷含量为0.69%。结论:远志中皮部总皂苷含量远远大于木部,远志总皂苷主要存在于根皮中。因此,在提取远志中的总皂苷时,应选用根皮为原料药材。更多还原

【Abstract】 Objective:To make a comparative analysis of the total saponins content in Polygalaceae phloem and xylem parts to guide clinical treatment.Methods:We determined the Polygalaceae total saponins content at the 575 nm with oleanolic acid as a reference substance and vanillin-Perchoric acid as a developer by using UV-visible spectrophotometry.Results:The total saponins content of xylem parts was 3.33%,and that of Polygalaceae phloem was 0.69%.Conclusion:The total saponins content in Polygalaceae xylem parts is much more than that of phloem parts,the total saponins in Polygalaceae mainly exists in xylem parts.Therefore,the xylem parts should be used as raw material to extract the total saponins.更多还原
