Abstract:
Nine compounds were extracted from the fruit body of Lactarius piperatus by silica gel column chromatography.According to the physical and chemical properties and spectroscopic analysis, they were identified as stearic acid(1), octadecanoic acid(2), phthalic acid diisobutyl ester(3), (22E,24R)-ergosta-5,22-dien-3β-ol(4), (22E,24R)-5α,8α-epidioxy-ergosta-6,22-dien-3β-ol(5), (22E,24R)-ergosta-7,22-dien-3β,5α,6β-triol(6), isolactarorufin(7), (22E,24R)-3β,5α,9α-trihydroxy-ergosta-7,22-dien-6-one(8) and (22E,24R)-ergosta-7,22-diene-3β,5α,6β,9α-tetrol(9), respectively. The compounds (1),(2),(3),(4) and (5) were all isolated from this wild edible mushroom for the first time.
