title: Cytotoxic constituents isolated from the fruit bodies of Hypsizigus marmoreus.
abstract: The bioactivity-guided fractionation of chloroform extracts of the fruit bodies of Hypsizigus marmoreus led to our isolation of (22E,24R)-ergosta-7,22-diene-3beta,5alpha,6beta-triol (1), ergosterol-3-O-beta-D-glucopyranoside (2), 5alpha,8alpha-epidioxyergosta-6,22-dien-3beta-ol (3), hypsiziprenol A9 (4), hypsiziprenol AA8 (5), hypsiziprenol AA9 (6) and hypsiziprenol BA10 (7). Among these seven isolates, compound 2 was identified for the first time from this plant. All compounds (1-7) exhibited moderate cytotoxicity towards cultured human colon carcinoma (HT-29), human breast carcinoma (MCF-7) and human hepatoblastoma (HepG-2) cell lines.
