ABSTRACT
The title Schiff base compound, C25H20N2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the imine group is approximately coplanar with the pyridine ring, with N-C-C-N torsion angles of 170.1â (3) and -172.0â (3)â Å. In the crystal, A and B dimers are linked by pairs of C-Hâ¯π inter-actions and further C-Hâ¯π bonds link the dimers into a three-dimensional network.
ABSTRACT
The antimutagenic activity of Sesbania javanica Miq. or Sano, an edible vegetable flower DMSO extract against aflatoxin B1 (AFB1) benzo (a) pyrene [B(a)P], was evaluated by means of the Ames' test. The Sesbania javanica Miq. flower DMSO extract showed a strong inhibitory effect against AFB1 and B(a)P mutagens. A search to isolate the major flavonoid in Sesbania javanica Miq. flower extract found the flavonol glycoside, Quercetin 3-2(G)-rhamnosylrutinoside, which was confirmed by its physicochemical properties as a major constituent of the flower. Quercetin 3-2(G)-rhamnosylrutinoside (207 microg/plate) also showeda strong inhibitory effect against AFB1 and B(a)P with a more than 70% inhibition rate.
