A new ceramide from Ramaria botrytis (Pers.) Ricken

Abstract

A new ceramide, (2S,2′R,3R,4E,8E)-N-2′-hydroxyoctadecanoyl-2- amino-9-methyl-4,8-heptadecadiene-1,3-diol (1), was isolated together with four known sterols, 5α,6α-epoxy-3β-hydroxy-(22E)-ergosta-8(14),22- dien-7-one (2), ergosterol peroxide (3), cerevisterol (4) and 9α-hydroxycerevisterol (5), from the fruiting bodies of Ramaria botrytis (Pers.) Ricken (Ramariaceae). The structure of the new compound was elucidated based on spectral data. © 2007 The Japanese Society of Pharmacognosy and Springer.
