    Abstract:

    Chickpeas(Cicer arietinum L) are highly nutritious legumes, in order to better understand its nutritional value, phenolics were extracted with 80% methanol solution, the content and antioxidant activity of phenolic compounds in different existing forms in the extract were determined, and analyze on qualitative, quantitative of 80% methanol solution. The results showed that the contents of total phenols and antioxidant activity in different forms of chickpeas were different, the phenolic content of glycoside phenolic compounds was the highest (0.81 mg/g), the content of free phenolic flavonoids was the highest (0.26 mg/g). The 80% methanol extracts were separated by UPLC-QTOF-MS, and identify 24 compounds including 4 phenolic acids and 12 flavonoids. Quantitative analysis by HPLC-QQQ-MS showed that p-hydroxybenzoic acid, coumalic acid and protocatechuic acid compounds are rich in chickpeas.
