Abstract

From the leaves of Uraria crinita DESV. (Leguminosae), six C-glycosylflavones (I-VI) were isolated. Vitexin (IV) and orientin (V) were identified by direct comparison with authentic samples, and vitexin 7-O-glucoside (I), orientin 7-O-glucoside (II), saponaretin 4'-O-glucoside (III), and vicenin II (VI) were identified with the help of degradation reactions and spectral analyses.
