Abstract

From Combretum paniculatum flowers, two diglucosylated derivatives from cyanidin and pelargonidin were identified using chromatographic (TLC), chemical (degradation by hydrolysis, tests of revelations) and spectral [UV-visible, ¹H-NMR (¹H and ¹³C, TOCSY-1D, DQF-COSY, NOESY-2D)] methods. These pigments were found to consist of cyanidin 3,5-O-β-D-diglu-copyranoside and pelargonidin 3,5-O-β-D-diglucopyranoside
