Abstract: In this experiment we identified 16 cyanidin glycosides from purple cabbage. Cyanidins were extracted from purple cabbage under the optimized conditions as follows: 50% ethanol containing 1% hydrochloric acid as extraction solvent, and a solid-to-solvent ratio of 1:10 (g/mL). The extract was purified with macroporous resin AB-8 and then hydrolyzed with acid at high temperature to free cyanidin glycosides. Furthermore, the hydrolysate was purified by C18 column chromatography, yielding cyanidin monomers with 99% purity.

Key words: purple cabbage, cyanidin, extraction and purification, crystallization
