Résumé :

Among several anthocyanins detected in the flowers of Ipomoea asarifolia, two acylated anthocyanins were isolated and studied using chemical, GC, mass spectrometric and extensive NMR methods (TOCSY-1D, DQF- COSY and HMBC measurements). The first anthocyanin was identified as cyanidin 3-O-[2-O-(6-O-(E-caffeoyl)-β-D-glucopyranosyl)-6-O-(E-caffeoyl)-β-D- glucopyranoside]-5-O-[β-D-glucopyranoside], and the new structure as cyanidin 3-O-[2-O-(6-O-(E-p-coumaroyl)-β-D-glucopyranosyl)-6-O-(E-caffeoyl)- β-D-glucopyranoside]-5-O-[β-D-glucopyranoside].
