A new monoterpene from the poisonous mushroom Trogia venenata, which has caused Sudden Unexpected Death in Yunnan province, China

摘要

A new monoterpene, 6,7,8-trihydroxy-2,6-dimethyloctanoic acid (1), and a known sesquiterpene, beta-caryophyllene 4R, 5R-oxide (2), as well as four known ergosta-steroids, 5 alpha, 8 alpha-epidioxyergosta-6,22dien- 3 beta-y1 linoleate (3), 3-O-beta-D-glucopyranosyl-22E, 24R-5 alpha, 8 alpha-epidioxyergosta- 6,22-dien (4), 5 alpha, 8 alpha-epidioxy-(22E, 24R)-ergosta6,22- dien-3 beta-ol (5) and (22E, 24R)-ergosta-7,22-dien-3 beta-ol (6), were isolated from the fruiting bodies of the mushroom Trogia venenata. The structures of these compounds were identified by the analysis of spectral data. All of the compounds were isolated from this mushroom for the first time.
