Chemical constituents from Ganoderma philippii / 中国中药杂志

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-11beta-ol (4), dihydroepicubenol (5), 5-hydroxymethylfuran carboxaldehyde (6), ergosta-7, 22E-dien-3beta-ol (7), ergosta-7, 22E-dien-3-one (8), ergosta-7, 22E-diene-2beta, 3alpha, 9alpha-triol (9), 6/beta-methoxyergo-sta-7, 22E-dien-3beta, 5alpha-diol (10), ergosta-4, 6, 8(14), 22E-tetraen-3-one (11), ergosta4, 6, 8-(14), 22E-etetraen-3beta-ol (12), 5alpha, 8alpha-epidioxy-ergosta-6, 22E-dien-3beta-ol (13), 7alpha-methoxy-5alpha, 6alpha-epoxyergosta-8-(14), 22E-dien-3beta-ol (14), ergosta-8, 22E-diene-3beta, 5alpha, 6beta, 7alpha-tetraol (15), and ergosta-5, 23-dien-3beta-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.
