Abstract: The content and distribution of flavonoids in different celery varieties were investigated by HPLC and spectrophotometer,DPPH and FRAP methods were used to evaluate the correlation between the flavonoids contents and antioxidant capacity of celery. The results showed that flavonoids mainly existed in the celery leaves,composed of luteolin and apigenin,while,quercetin was trace. The contents of flavonoids in celery varieties showed quite different,‘Shengjie White Stalk’had the highest content of total flavonoids,reached 732.21 mg &#8226; kg-1,and followed by‘Zambia’,‘Shanxi Purple Stalk’and‘Shanxi Lan County’,556.93 mg &#8226; kg-1,475.74 mg &#8226; kg-1 and 346.48 mg &#8226; kg-1 respectively. The total flavonoids in variety‘Ventura’was only 241.41 mg &#8226; kg-1. The results also showed that the contents of total flavonoids detected by spectrophotometer method are 2.64–7.14 folds of that of HPLC which has the different rank of celery varieties. For the celery stalk,the correlation coefficient reached 0.843 and 0.798(P < 0.01)between
