摘要: 为对香芸火绒草(Leontopodium haplophylloides)的化学成分进行分离纯化及抗炎活性研究,本实验通过正、反相硅胶柱色谱、Sephadex LH-20凝胶柱色谱,从香芸火绒草的中分离得到17个化合物,并运用现代波谱技术(1H NMR、13C NMR)分别鉴定为:咖啡酸(1)、咖啡酸-β-苯乙醇酯(2)、原儿茶酸(3)、tyrosol(4)、对羟基苯甲酸(5)、邻苯二甲酸二丁酯(6)、异莨菪亭(7)、7-(2,3-epoxy-3-methyl-3-butyloxy)-6-methoxycoumarin(8)、洋芹素(9)、牡荆素(10)、5-羟基-4′,7-二甲氧基-6,8-二甲基黄酮(11)、5,7-二羟基-8-甲氧基黄酮(12)、百蕊草素Ⅲ(13)、methyl flavogallonate(14)、3,5,7,3′,4′-pentahydroxyflavone (15)、木犀草素(16)、高良姜素(17),其中化合物1~16为首次从该植物中分离得到;经抗菌筛选发现发化合1、2、4~6、9、10、13~17对大肠杆菌、金黄色葡萄球菌及蜡状芽孢菌有抑制作用。

Abstract: This paper reported the chemical constituents and anti-bacterial activties of Leontopodium haplophylloides Hand.-Mazz.Seventeen compounds were isolated from Leontopodium haplophylloides by column chromatography on silica gel,ODS,Sephadex LH20 and identified by chemical and special analysis.Their structures were elucidated as caffeic acid (1),phenethyl caffeate (2),protocatechuic acid (3),tyrosol (4),p-hydroxybenzoic acid(5),dibutyl phthalate(6),isoscopoletin(7),7-(2,3-epoxy-3-methyl-3-butyloxy)-6-methoxycoumarin(8),apigenin (9),vitexin (10),5-hydroxy-4′,7-dimethoxy-6,8-dimethyl flavones (11),5,7-dihydroxy-8-methoxyflavone (12),kaempferol 3-glucorhamnoside (13),methyl flavogallonate (14),3,5,7,3′,4′-pentahydroxyflavone (15),luteolin (16),galangin (17),among which compounds 1-16 were obtained from this plant for the first time.After antibacterial test,1,2,4-6,9,10 and 13-17 have strong inhibitory effects on E.coli,Staphylococcus aureus,and Bacillus subtilis.

Key words: Leontopodium haplophylloides, phenethyl caffeate, dibutyl phthalate, anti-bacterial activities
