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 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 H 2 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.
