Abstract: 目的对赤芝子实体的化学成分进行研究.方法利用各种色谱技术进行分离,主要采用一维、二维核磁谱及X-衍射分析进行结构鉴定.结果从赤芝子实体中分离得到4个化合物,其结构经波谱和X-衍射分析鉴定为:3β-氧-甲酰基-7β,12β-二羟基-4,4,14α-三甲基-5α-胆甾-11,15-二酮-8-烯(E)-24-酸(3β-oxo-formyl-7β,12β-dihy-droxy-4,4,14α-trimethyl-5α-chol-11,15-dioxo-8-ene(E)-24-oic acid,Ⅵ);3β-氧-甲酰基-7β,12β-二羟基-5α-羊毛甾-11,15,23-三酮-8-烯(E)-26-酸(3β-oxo-formyl-7β,12β-dihydroxy-5α-lanost-11,15,23-trioxo-8-en(E)-26-oic acid,Ⅶ);麦角甾醇(ergosterol,Ⅷ);麦角甾-7,22-二烯-3β-醇(ergosta-7,22-dien-3β-ol,Ⅸ).结论化合物Ⅵ和Ⅶ为新化合物.
