To study the chemical constituents of Erigeron breviscapus. The constituents were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and physical data. Five compounds were isolated and identified as 3, 5, 6, 4'-tetrahydroxy-7-methoxy flavonoid(I); 5, 7, 4'-trihydroxy flavonoid(II); 3, 5, 6, 7, 4'-pentahydroxy flavonoid(III); scutellarein (IV) and 5, 7, 4'-trihydroxy flavanone(V). Compounds I, III and V were isolated from this plant for the first time.
