Abstract:Five compounds were isolated from the aerial part of Conyza blinii. On the basis of physicochemical properties and spectroscopic analysis,they were identified as α spinasterol,5,8 dihydroxy 7,3′,4′ trimethoxyflavone,caffeic acid,quercetin and syringic acid.All these compounds were isolated from the plant of C.blinii for the first time.
