Abstract

Seven flavonoids were isolated from the flower of Clerodendrum trichotomum. Their structures were identified as apigenin (1), genistein (2), chrysoeriol (3), genistein 7-O-glucoside (4), kaempferol 3-O-glucoside (5), isorhamnetin 3-O-glucoside (6) and apigenin 7-O-glucoside (7) on the basis of spectral data. These compounds were isolated from C. trichotomum for the first time. The antioxidant activity of compounds 1-7 were evaluated by the ORAC (oxygen radical absorbance capacity) assay, and the ORAC values were expressed as relative trolox equivalent. All isolated compounds exhibited antioxidant activity.
