石松非生物碱成分研究

Non-alkaloid Constituents from Lycopodium japonicum

用层析方法从石松(Lycopodium japonicum)全草的乙醇提取物中分离得到8个化合物。通过波谱分析,分别鉴定为3β,21β,24-trihydroxyserrat-14-烯-16-酮(1)、3α,21β,24-trihydroxyserrat-14-烯-16-酮(2)、3β,21β,24-trihydroxyserrat-14-烯(3)、3α,21β,24-trihydroxyserrat-14-烯(4)、onocerin(5)、豆甾-5-烯-3β,7α-二醇(6)、豆甾-5-烯-3β,7β-二醇(7)和β-谷甾醇(8)。其中化合物1为新化合物,化合物3、4、6、7为首次从该植物中分离获得,化合物2的波谱数据系首次报道。

Eight compounds were isolated from the ethanol extract of Lycopodium japonicum.On the basis of spectral data,they were identified as 3β,21β,24-trihydroxyserrat-14-en-16-one（1）,3α,21β,24-trihydroxyserrat-14-en-16-one（2）,3β,21β,24-trihydroxyserrat-14-en（3）,3α,21β,24-trihydroxyserrat-14-en（4）,onocerin（5）,stigmasta-5-en-3β,7α-diol（6）,stigmasta-5-en-3β,7β-diol（7）,β-sitosterol（8）.Compound 1 was a new compound,and compounds 3,4,6,7 were obtained from this species for the first time,and the spectral data of compound 2 was reported for the first time.
