心叶兔儿风的化学成分研究

 目的 系统研究心叶兔儿风的化学成分。方法 采用色谱方法分离纯化,运用多种波谱分析手段进行化合物结构鉴定。结果 从心叶兔儿风中共分离得到7个化合物,经结构鉴定分别为蒲公英甾醇(1)、β-谷甾醇(2)、紫花前胡苷元(3)、对二苯酚(4)、瑞香内酯(5)、芹菜素(6)、熊果苷(7)。结论 化合物1～5和化合物7均为首次从该植物中分离得到,化合物1、3~5为首次从该属中分离得到。

Chemical Constituents from Ainsliaea bonatii

OBJECTIVE To study the chemical constituents in Ainsliaea bonatii. METHODS The column chromatographic techniques were used to isolate the constituents in A. bonatii. EI-MS and NMR were used to identify the constituents structures. RESULTS Seven compounds were isolated and identified from the extract of A. bonatii,whose structures were elucidated as taraxasterol(1),β-sitosterol(2),nodakenetin(3),1,4-benzenediol(4),daphnetin(5),apigenin(6) and β-arbutin(7). CONCLUSION Compounds 1-5 and 7 were isolated for the first time from this plant,and 1,3-5 were isolated for the first time from Ainsliaea genus.
