Abstract: Secondary metabolites of mangrove endophytic fungus Pestalotiopsis versicolor fermented in solid medium under high salinity environment were studied. Nine compounds were isolated using various chromatographic purification methods,including column chromatography (CC), preparative thin-layer chromatography (PTLC), high-performance liquid chromatography (HPLC), and Sephadex LH-20. Their structures were identified as pestalachloride B (1), 1,6,8-trihydroxy-3-(hydroxymethyl) anthraquinone (2), emodin (3), ergosterol-6,22-diene-5α, 8α-epidioxy-3-ol (4), 3β-hydroxyl-5-cholestene-6-ketone (5),indole-3-carboxaldehyde (6), 4,6-dihydroxy-1(3H)-isobenzofuranone (7), 2-(4-hydroxyphenyl) ethanol (8), and 4-hydroxybenzaldehyde (9) according to their physicochemical properties and spectral data.Compound 1-3, 6-8 were isolated from P.versicolor for the first time.
