Flavonoid glycosides from Colebrookea oppositifolia

Phytochemistry, 1996
Two new flavonoid glycosides were isolated from the bark of Colebrookea oppositifolia, together with three known flavonoid aglycones. On the basis of spectral evidence, the structures of the two flavonoid glycosides were established as negletein 6-O-beta-D-glucopyranoside and 5,7,2'-trihydroxyflavone 2'-O-beta-D-glucopyranoside, respectively.
