Chaenomeles is an important source for food industry in China, and its planting area is expanding year by year. This study was conducted to evaluate different varieties of Chaenomeles by comparing the chemical compositions, antioxidant activity and alpha-glucosidase inhibitory activity of peels and fleshes from twelve varieties of Chaenomeles. In the results, peels of Chaenomeles contain more phenolics, flavonoids and triterpenes, and show better antioxidant activity and alpha-glucosidase inhibitory activity than their fleshes. All varieties of Chaenomeles perform different depend on cultivar and climatic conditions. Oleanolic acid, ursolic acid, protocatechuic acid, rutin, catechin, caffeic acid, syringic acid, epicatechin, hyperin, quercetin, kaempferol and chlorogenic acid are main active compounds in Chaenomeles. Zheng'an, Liufu, Zimugua1, Qijiang and Changjun get Top five scores. This is the first study on the peels and fleshes of twelve varieties of Chaenomeles, and it gives insights into variety selection in the planting and production of Chaenomeles.
