Abstract: The natural calyx pigment of Physalis alkekengi was extracted with several different reagents and its physical andchemical characters were studied.The results indicated that this pigment was most efficiently extracted with acetone and theabsorb apex of the pigment was 406nm. It seldomly affected the stability of the pigment in different temperatures. Differentfood additives almost showed no effect on it. The sun light would impaire the luster and the stability of the pigment. The pigmentshowed obvious antimicrobial effect.

Key words: Phvsalis alkekengi, calyx pigment of Physalis alkekengi, extract, physical and chemical characters
