Abstract


ABSTRACT
Two isomer flavonoids, 7,4´-dihydroxyflavanon (1) and 7,4´-dihydroxyisoflavanon (2) were isolated
from the bark of Sesbania grandiflora L. Their structures were determined based on spectroscopic
data such as UV, IR, MS, 1D and 2D NMR.
Keywords : Sesbania grandiflora L., flavonoid, 7,4´-dihydroxyflavanon, 7,4´-dihydroxyisoflavanon
