Pharmacognostical study and chemical analysis of Aralia taibaiensis

This article deals with pharmacognostical study and chemical analysis of Araliataibaiensis Z.Z. Wang et H.C. Zheng, Main identification features of the original plant and itscrude drug were described,and a survey of distribution area of the original plant was also made;histological and powder identification shows that stone cell ,fiber,cluster crystal,secretory canal,starch grain,and towering leaf lower epidermal cell are principal microscopic identification chrac-teristics; assay of oleanolic acid shows the content in root cortex,stem bark and leaf are respec-tively 5. 24%,4. 58%,1. 03%, Chemical analysis indicates essential oil from root cortex containsat least 25 consittuent in which santalol,hexadecanoic acid etc. are the major ingredients.
