X-Ray structure of lyofoligenic acid, a novel B-homotriterpene
Abstract
The structure of lyofoligenic acid has been determined as 3α,24,25-trihydroxy-9(10 → 19)-abeo-lanost-5(10)-en-32-oic acid (II) by chemical and spectroscopic studies as well as by X-ray crystallographic analysis of the p-bromobenzoate methyl ester(III) or (II).
