Abstract
AbstractA 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 of β–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 ester 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 acetyl derivation of sitosteryl–β–D–glucopyranoside.
