A new flavanoid from the flowers of Azadirachta indica

Nat Prod Res. 2006 Mar;20(3):241-5. doi: 10.1080/14786410500059318.

Abstract

Studies on the chemical constituents of the flowers of Azadirachta indica have led to the isolation of one new flavanone named as azharone (5,7,4'-trihydroxy-3'-(3''-methyl-2'',3''-epoxybutyl)flavan-4-one (3)) along with two known constituents azadirone (1), and isoazadironolide (2). Their structures have been elucidated through spectral studies including 2D-NMR (COSY-45, NOESY, J-resolved, HMQC, HMBC) experiments.
