【摘要】 从鹅不食草(Centipeda minima)全草的乙醇提取物中分离得到3个乌苏烷型三萜,其中一个新化合物用波谱学方法鉴定为ursane-20(30)-en-3β,16β,21α-triol(1),二个已知化合物的结构分别为taraxasterol acetate(2),taraxasterol(3)。抗菌试验表明化合物2和3具有较强的抗菌活性。更多还原

【Abstract】 A new triterpene,ursane-20(30)-en-3β,16β,21α-triol(1),together with two known compounds,taraxasterol acetate(2) and taraxasterol(3),was isolated from the whole plants of Centipeda minima.Their structures were identified by spectroscopic analysis.Antibacterial properties of compounds 2 and 3 were evaluated against eight disease-associated microorganisms by the agar dilution method,Both of them displayed potential antibacterial activities.更多还原
