Abstract:The chemical investigation on Ganoderma philippii led to the isolation of sixteen compounds by silica gel and Sephadex LH-20 column chromatography. On the basis of spectroscopic data analyses, their structures were elucidated as 2, 5-dihydroxyacetophenone(1), methyl gentisate(2), (S)-dimethyl malate (3), muurola-4, 10(14)-dien-11β-ol(4), dihydroepicubenol(5), 5-hydroxymethylfuran carboxaldehyde(6), ergosta-7, 22E-dien-3β-ol(7), ergosta-7, 22E-dien-3-one(8), ergosta-7, 22E-diene-2β, 3α, 9α-triol(9), 6β-methoxyergo-sta-7, 22E-dien-3β, 5α-diol(10), ergosta-4, 6, 8(14), 22E-tetraen-3-one(11), ergosta-4, 6, 8-(14), 22E-etetraen-3β-ol(12), 5α, 8α-epidioxy-ergosta-6, 22E-dien-3β-ol(13), 7α-methoxy-5α, 6α-epoxyergosta-8-(14), 22E-dien-3β-ol(14), ergosta-8, 22E-diene-3β, 5α, 6β, 7α-tetraol(15), and ergosta-5, 23-dien-3β-ol, acetate(16). All the compounds were obtained from this fungus for the first time, and compounds 4 and 5 were isolated from the Ganoderma genus for the first time.
