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 α-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 α-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.
木瓜是中国食品工业的重要原料，其种植面积逐年扩大。本研究通过比较 12 个木瓜品种的果皮和果肉的化学成分、抗氧化活性和α-葡萄糖苷酶抑制活性，对不同品种的木瓜进行了评价。结果表明，木瓜果皮中含有更多的酚类、类黄酮和三萜类化合物，具有更好的抗氧化活性和α-葡萄糖苷酶抑制活性。所有品种的木瓜的表现都因品种和气候条件而异。齐墩果酸、熊果酸、原儿茶酸、芦丁、儿茶素、咖啡酸、丁香酸、表儿茶素、金丝桃苷、槲皮素、山柰酚和绿原酸是木瓜中的主要活性化合物。政安、六福、紫木瓜 1 号、綦江和长春得分最高。这是对 12 个木瓜品种的果皮和果肉的首次研究，为木瓜的种植和生产中的品种选择提供了参考。
