目的 对火绒草全草的化学成分进行分离和鉴定。方法 采用硅胶、葡聚糖凝胶LH - 20柱色谱及反相高效液相色谱对化合物进行分离纯化，根据波谱数据对化合物结构进行解析。结果 鉴定出10种化合物，分别为咖啡酸乙酯（11）、芹菜素（2）、对羟基苯甲酸（3）、原儿茶醛（4）、原儿茶酸（5）、咖啡酸（6）、槲皮素（7）、木犀草素（8）、对羟基肉桂酸（9）和阿魏酸（10）。结论 化合物1 - 3、8首次从火绒草中分离得到，化合物1 - 3首次从火绒草属植物中纯化得到。
Objective To isolate and identify the chemical constituents from whole plant of Leontopodium leontopodioides.Methods Compounds were isolated and purified on the silica gel,sephadex LH-20 chromatograph and RP-HPLC.The structures of chemical compounds were elucidated on the basis of spectra data.Results Ten compounds were identified as ethyl caffeate(11),apigenin(2),p-hydroxybenzoic acid(3),protocatechuic aldehyde(4),protocatechuic acid(5),caffeic acid(6),quercetin(7),luteolin(8),p-hydroxy cinnamic acid(9)and ferulic acid(10),respectively.Conclusions Compounds 1-3,8 are isolated from L.leontopodioides for the first time,and compounds 1-3 are purified from Leontopodium for the first time.
