Anthocyanin Pigments of Siahe Sardasht Grapes

Abstract

The anthocyanins of Siahe Sardasht variety (Vitis vinifera L. var. S.S.) were extracted from freezed samples and were purified by adsorption on cation-exchange resin column. Individual pigments were separated by TLC on cellulose plates. Monomeric anthocyanin content that was determined by pH-differential, was 1740.11±3.58 mgL?1 (based on malvidin 3-glucose). Five major pigments were identified by 1H-NMR, IR and UV-Visible spectroscopies. All pigments were acylated with acetyl groups and three of them were acylated with malonyl groups
