title: The structures of new lanostane triterpenes from the fruiting bodies of Hebeloma senescens.
abstract: Three new lanostane triterpenes, hebelomic acids B[4], E[5], and F[6], were isolated from the inedible mushroom Hebeloma senescens. The latter two compounds are acyl derivatives of the new triterpene senescensol (12-deoxycrustulinol) [12]. The structures of compounds 4-6, including the absolute configuration of the 3-hydroxy-3-methylglutaric acid moiety, were established on the basis of spectral and chemical evidence.
