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.

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575 nm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。

The mean retention time in liver and lung was longer and was eliminated more slowly than other organs. It suggested that there was a correspondence relationship between OADHPS and its hepato-protection. After oral administration, 14. 8％ of OADHPS was excreted as protype. It was assumed that 10.0％ of OADHPS was metabolized in vivo whereas 75. 2％ of OADHPS destroyed in gastrointestinal tract.

药物在肝、肺等组织中的平均滞留时间较长，消除相对较慢，这恰好与齐墩果酸具有的较强的保肝作用相呼应。24h尿中原型药物排泄量占给药量的3.21％，结合绝对生物利用度为21.7％，推测被吸收的药物中约14.8％以原型排泄。
