Notes:
Gas chromatographic analysis of the methylated sugar residues obtained from the band-2 pigment of Vitis vinifera var. Tinta Pinheira indicated that the acyl function, p-coumaric acid, was most likely attached at the four-position on the glucose portion of the anthocyanins. The possibility of an acid-catalyzed migration of the acyl function during the methylation process cannot, however, be ruled out completely. The acylated pigments of band 2 are thus considered to be the 3-monoglucosides of malvidin, peonidin, petunidin, and delphinidin, each acylated with p-coumaric acid at the four-position on the glucose.
