A new benzofuran derivative,2-acetyl-5-methoxy-6-hydroxy-benzofuran (1),along with five known analogues are isolated from the roots of Ligularia latihastata (compositae)which is used as a folk medicine in China.Their structures are then elucidated on the basis of extensive spectroscopic data,including 1 D and 2D NMR techniques.Biological screening studies indicate that 2-isopropenyl-5 -acetyl-6 -hydroxy-benzofu-ran(2)exhibites potent cytotoxic activity against Hela human cervical carcinoma cancer cells with IC50 values of 36 .0 μmol/L.
