ABSTRACT: From yellow petals of Blue Mahoe, besides the known flavonoids gossypetin
and gossypitrin, a new one gossypetin derivative was isolated from ethanolic
extracts after Soxhlet extraction. Hence, in this study, we present a
validated, sensitive and reliable NMR method for the simultaneous
identification of flavonoids in this flower drug. Structure analyses of this
flavonoid, revealed the identical glycoside moiety attached to a flavonol
skeleton like gossypitrin, for which the structure of gossypetin-3'-O-β-glucoside
was deduced from extensive NMR experiments.
