These latter compounds are most probably formed by esterification of 2 with the solvent (acidified methanol) during the isolation process. In addition to 1 and 2, two analogues of 2 methylated at the terminal carboxyl group of the acyl moiety (3) or at the aglycone carboxyl (4), respectively, were also identified. This aglycone, 5-carboxy-2-(3,4-dihydroxyphenyl)-3,8-dihydroxy-pyrano-1-benzopyrylium, is with exception of the substitution pattern on the phenyl ring similar to carboxypyranomalvidin (vitisidin A) recently isolated from red wines. The structures of 1 and 2 were identified as the 3-O-beta-glucopyranoside and 3-O-(6"-O-malonyl-beta-glucopyranoside) of 5-carboxypyranocyanidin, respectively. ![]() Four anthocyanins with the same novel 4-substituted aglycone, carboxypyranocyanidin, have been isolated from acidified, methanolic extracts of the edible scales as well as from the dry outer scales of red onion, Allium cepa L.
