Isolation, for the first time, of a flavonoid glycoside and the (±)-catechin from the aerial parts of Ebenus pinnata
Written by sctunisie no commentsFrom the aerial parts of Ebenus pinnata, a flavonol diglycoside and a mixture of two flavan-3-ol enantiomers were isolated for the first time and their structures elucidated as quercetin 3-O-α-L-rhamnosyl-(1 → 6)-O-β-D-glucopyranoside 1, and (±)-catechin 2. Their structures were established by ESIMS, EIMS, and 1D and 2D NMR spectral analysis.
