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 .

Key words: Centipeda minima
