【Abstract】 Eleven known compounds, 1-O-β-D-glucopyranosyl-(2S,3R,4E,8E,2′R)-2-N-(2′-hydroxypalmitoyl)-9-methyl 4,8- sphingadienine(cerebroside B)(1),1-O-β-D-glucopyranosyl-(2S,3R,4E,8E,2′R)-2-N-(2′-hydroxyoctadecanoyl)-9-methyl -4,8-sphingadienine (cerebroside D)(2),5α,8α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol (3), (22E,24R)-ergosta-7,22-dien-3β-ol (4), (24S)-ergosta-7-ene-3β-ol (5), uracil (6), adenine (7), thioacetic anhydride (8), as well as ethyl-β -D -glucopyranoside (9), D-allitol (10) and stearic acid (11) have been isolated from the fruiting bodies of Russula ochroleuca (Pers.) Fr., Basidiomycetes. Their structures were determined by means of spectral and chemical methods. It is the first report that compound 8 was isolated as a natural product.更多还原
