From Combretum paniculatum flowers, two diglucosylated derivatives fromcyanidin and pelargonidinwere 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-â-Ddiglucopyranoside and pelargonidin 3,5-O-â-D- diglucopyranoside.
