Abstract
Among several anthocyanins detected in the flowers of Ipomoea asarifol ia, 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 cyani din a-D-glucopyranoside]-5-O-[beta-D-glucopyranoside], and the new str ucture as cyanidin pyranosyl)-6-O-(E-caffeoyl)-beta-Dglucopyranoside] -5-O-[beta-D-glucopyranoside].
