Novel biflavonoids from the stem bark of Ochna integerrima.
Two new biflavonoids, namely, 6'"-hydroxylophirone B (1) and 6'"-hydroxylophirone B 4"'-O-beta-glucoside (2), were isolated from the stem bark of Ochna integerrima, together with five known compounds. The structures of 1 and 2 were determined by spectral data interpretation.
