Galinsosides A (1) and B (2), new flavanone glucosides together with two known flavanones, 7,3',4'-trihydroxyflavanone (3) and 3,5,7,3',4'-pentahydroxyflavanone (4) have been isolated from an ethyl acetate-soluble fraction of Galinsoga parviflora. Their structures were assigned on the basis of spectral studies. Compound 1 showed significant antioxidant and urease inhibitory activity while compound 2 was moderately active. On the other hand, 2 showed inhibitory potential against alpha-glucosidase.
