OBJECTIVE: To study the chemical constituents of Erigeron breviscapus. METHOD: The constituents were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and physical data. RESULT: 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). CONCLUSION: Compounds I, III and V were isolated from this plant for the first time.
