The changes of total flavonoids content,total polyphenol content and antioxidant activities of Zanthoxylum bungeagum Maxim.and the correlation between them were investigated.The results indicated that:（1）The total flavonoid content and total polyphenol content were accumulated during the growth of Z.bungeanum Maxim..The total flavonoid content was increasing with the maturity level of the fruit,and reached its highest level in August (164.14 mg/g).Total polyphenol content was increased rapidly in the early periods of growth and reached its highest level in June (77.17 mg/g).Then it decreased rapidly to 46.23 mg/g in August.(2)The correlation between the total flavonoid content,total polyphenol content and reducing power was significantly positive (P<0.01),and the correlation coefficients are 0.977 and 0.960,respectively;there is also a significant positive relationship between flavonoid content,polyphenol content and ·OH^- scavenging capacity,and their correlation coefficients are 0.917 and 0.933,respectively.The above results indicated that the Z.bungeagum Maxim.pericarp can be used as a valuable source of antioxidant products.
