- 中文摘要: A new component of the steryl glucoside of Panax ginseng C.A. Meyer(Araliaceae) has been identified as sitosteryl-β-D-(6-O-fattyacyl)-glucopyranoside (1). Its gross structure, as a monoester ofβ-sitosteryl, campesteryl and stigmasteryl-β-D-glucoside, was derived from a study of the products formed on methanolysis and on acid hydrolysis. The location of the fatty eater was established by comparison of the proton chemical shift for H2 C-6 in its tribenzoyl derivative with the chemical shifts for the corresponding protons in model benzoyl and derivation of sitosteryl-β-D-glucopyranoside.
