Tridaxidone, a new flavone glycoside (3) and two bergenin derivatives (4) and (5) have been isolated along with two known flavone glycosides (1) and (2) from the ethyl acetate soluble portion of the ethanolic extract of Tridax procumbens. The structures of 3, 4 and 5 were established through spectroscopic studies.
