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。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.
