摘要/Abstract

利用多种色谱分离方法对垂穗石松的化学成分进行研究，从其全株的乙醇提取物中分离得到2个化合物，用MS和NMR等多种现代波谱技术确定了化合物的结构，经鉴定分别为3β，14α，15α，21β-四羟基-15-（3'-甲氧基-4'-羟基苯甲酰）-千层塔烷（1）和16-酮基-3β，21α-二羟基-14-千层塔烯（2）.其中化合物1为新化合物，2个化合物均为首次从小石松属植物分离.
关键词: 垂穗石松, 千层塔三萜, 抗甲型流感病毒
Two serratane triterpenoids, 3β,14α,15α,21β-tetrahydroxyserrat-15-(3'-methoxyl-4'-hydroxybenzoate) (1) and 16-oxoserrat-14-en-3β,21α-diol (2), were isolated from the whole plant of Lycopodiella cernua. Compound 1 was a new one. The structures of these compounds were identified by analysis of spectral data. These two compounds were isolated from Lycopodiella genus for the first time.
Key words: Lycopodiella cernua, serratane triterpenoid, anti-influenza A virus
