Chickpeas are a very important legume crop and have abundant protein, carbohydrate, lipid, fiber, isoflavone, and mineral contents. The chemical compositions of the four chickpea species (Muying-1, Keying-1, Desi-1, Desi-2) from Xinjiang, China, were analyzed, and 46 different flavonoids in Muying-1 were detected. The moisture content ranged from 7.64 ± 0.01 to 7.89 ± 0.02 g/100 g, the content of starch in the kabuli chickpeas was greater than that in the desi chickpeas, the total ash content ranged from 2.59 ± 0.05 to 2.69 ± 0.03 g/100 g and the vitamin B1 content of the chickpeas ranged from 0.31 to 0.36 mg/100 g. The lipid content ranged from 6.35 to 9.35 g/100 g and the major fatty acids of chickpeas were linoleic, oleic, and palmitic acids. Both kabuli and desi chickpeas have a high content of unsaturated fatty acids (USFAs), Muying-1 and Desi-1 contained the highest level of linoleic acid, and Keying-1 had the highest oleic acid content. The protein level ranged from 19.79 ± 2.89 to 23.38 ± 0.30 g/100 g, and the main amino acids were aspartic acid, glutamic acid, and arginine acid. The four chickpea species had significant amounts of essential amino acids (EAAs). Forty-six varieties of flavonoids in Muying-1 were determined by ultra high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UPLC-QqQ-MS) analysis, and there were higher levels of conjugate flavonoids (55.95%) than free flavonoids (44.05%). Isoflavones were the most abundant flavonoids in Muying-1, and among the isoflavones, daidzin had the highest content, followed by biochanin A and genistin. Muying-1 was rich in daidzin, biochanin A, genistin, troxerutin, isorhamnetin, astilbin, L-epicatechin, astragalin, acacetin, hyperoside, and myricitrin. Information provided in the study will be helpful to further understand the chemical composition of chickpeas and be beneficial to the development of chickpeas.
