Phytochemical And Antimicrobial Study of Glycosmis mauritiana (Lam.) Tanaka

We have successfully extracted a novel geranyl flavanone from the root barks of Glycosmis mauritiana. The structucture was eleducated as 6-geranyl-5-hydroxy-3′ -methoxy-7, 8- (2", 2"-dimethyl pyrano) flavanone- 4'-O-D-glucopyranoside (GM-1), along with 3 known compounds (GM-2, GM-3, GM-4), was separated and identified by a variety of spectroscopic techniques. The range of inhibition against four bacteria examined was shown to be 4-25 mm; the GM-1 revealed a significant inhibition zone.
