摘要
目的对扁枝石松全草80%乙醇提取物中的石杉型三萜类化学成分进行研究。方法利用正相和反相硅胶柱色谱方法进行分离纯化,通过MS,1H-NMR,13C-NMR波谱数据鉴定化合物结构。结果从扁枝石松共分离得到7个石杉型三萜类化合物,分别鉴定为serrat-14-en-3β,21α-diol①;serrat-14-en-3β,21β-diol②;3β-hydroxy-21α-acetoxy-14-serraten③;3β,21β-dihydroxy-14-serraten-24-oic acid(lycernuic acid A,④;14-serraten-3α,21β,24-triol(lycoclavanol,⑤,3α,20β,21β-trihydroxy-14-serraten-24-oic acid⑥;21-episerratenediol-3-α-L-arabinopyranoside(inundoside E,⑦。结论化合物7为首次从该属植物中分离得到,化合物3为首次从该植物中分到。
Objective To study the serratene-type triterpenoids from the 80 % alcohol extract of Diphasiastrum complanatum.Methods The compounds were isolated and purified by silica gel,C18 reverse-phase silica gel column chromatographic methods,and their structures were elucidated by spectral analysis.Results Seven serratene-type triterpenoids were obtained and identified as serrat-14-en-3β,21α-diol(1),serrat-14-en-3β,21β-diol(2),3β-hydroxy-21α-acetoxy-14-serraten(3),3β,21β-dihydroxy-14-serraten-24-oic acid(lycernuic acid A,4),14-serraten-3α,21β,24-triol(lycoclavanol,5),3α,20β,21β-trihydroxy-14-serraten-24-oic acid(6),21-episerratenediol-3-α-L-arabinopyranoside(inundoside E,7).Conclusion Compound 7 was isolated from Diphasiastrum and compound 3 from the plant for the first time.
