摘要
目的研究艳丽齿唇兰石油醚提取部位的化学成分。方法采用反复硅胶柱色谱、Sephadex LH-20柱色谱及制备薄层方法对艳丽齿唇兰石油醚部位进行分离、纯化,通过理化常数和波谱分析鉴定化合物的结构。结果从艳丽齿唇兰的石油醚萃取部位分离鉴定出6个化合物,包括2个木栓烷型三萜、1个羽扇豆烷型三萜、2个植物甾醇和1个长链脂肪烷烃,其结构分别鉴定为:木栓酮(1)、木栓烷(2)、豆甾醇(3)、sorghumol(4)、十八烷(5)、菜油甾醇(6)。结论 6个化合物均为首次从该植物中分离得到,化合物2为首次从开唇兰属植物中分离得到。
Objective To investigate the chemical constituents with petroleum ether soluble fraction from whole herbs of Anoectochilus moulmeinensis（Par.et Rchb.F.） Seidenf..Methods The chemical constituents were isolated and purified by repeated column chromatographies with silica gel,sephadex LH-20 and preparation TLC.Their structures were identified by their physical and spectral data.Results Six compounds were isolated,including two fiedelanes,one lupane,two phytosterols and one long chain aliphatic alkane,and elucidated as follows： friedelin（1）,friedelane（2）,stigmasterol（3）,sorghumol（4）,octadecane（5）and campesterol（6）.Conclusion Compounds 1-6 were isolated from this species for the first time,and compound 2 were isolated from genera Anoectochilus for the first time.
