Popis: 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 anthccyanin 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 .
