摘 要 ：利用硅胶柱层析和Sephadex LH-20凝胶柱层析分离手段，从高等真菌齿菌(Hydnellum sp.No.2)子实体的甲醇提取物中分离鉴定了7个化合物，经现代光谱学技术鉴定为麦角甾-7，22-二烯-3β-醇(1)、5α,8α-过氧麦角甾-6,22-二烯-3β-醇(2)、(22E,24R)-3β-羟基-24-甲基胆甾-5,22-二烯-7-酮(3)、对羟基苯甲酸甲酯(4)、(24R)-麦角甾-7,22-二烯-3β,5α,6β-三醇(5)、Tuberoside(6)和脑苷脂B(7)。化合物4、5、6、7为该属首次报道。

Abstract:Seven compounds were isolated from the fruiting bodies of Hydnellum sp.No.2 by silica gel and Sephadex LH-20 column chromatography.With combine analysis of spectral data and literature,their structures were identified as ergosta 7,22-dien-3β-ol (1),ergosterol peroxide (2),(22E,24R)-3β-hydroxy-24-methylcholesta-5,22-dien-7-one (3),nipagin (4),(24R)-ergosta-7,22-diene-3β,5α,6β-triol (5),tuberoside (6),and cerebroside B (7).Compounds 4,5,6 and 7 were obtained from this genus for the first time.
