Sterol Constituents from Seven Mushrooms

抄録

Six new sterols, 5α, 6α;8α, 9α-diepoxy-(22E, 24R)-ergost-22-ene-3β, 7α-diol (1), 5α, 6α;8α, 9α-diepoxy-(22E, 24R)-ergost-22-ene-3β, 7β-diol (2), 5α, 6α-epoxy-(22E, 24R)-ergosta-8, 22-diene-3β, 7β-diol (3), (22E, 24R)-23-methylergosta-7, 22-diene-3β, 5α, 6β-triol (4), (22E, 24R)-23-methulergosta-7, 22-diene-3β, 5α, 6β, 9α-tetrol (5) and (24S)-ergost-7-ene-3β, 5α, 6β, 9α-tetrol (6), have been isolated from seven mushrooms, Amanita pantherina, Amantia virgineoides, Lactarius piperatus, Lyophyllum shimeji, Tricholoma portentosum, Hypsizigus marmoreus and Lentinula edodes together with eighteen known ones (7-24). The structures of these new compounds were elucidated on the basis of their spectral data.
