Flavonoids with antibacterial and antioxidant potentials from the stem bark of .

Two flavonol glycosides; U1: naringenin-7--glucoside and U2: kaempferol-3--glucoside were isolated for the first time, from ethyl acetate fraction of the stem bark of a traditional medicinal plant called . IR and NMR spectroscopy were used to elucidate the structures of the isolated compound. The two compounds were active against the 7 tested microorganisms; and The zones of inhibition of the compounds ranged from 16 to 23 mm. The MIC value was as low as 6.25 μg/mL against and . The radical scavenging activity of compound U1 and U2 was 80 and 85 % at 240 μg/mL, while that of the standard drug was 98% at 240 μg/mL. The results show an existent possibility of using the plant for the treatment of microbial diseases.
