The changes of fruit quality parameters,antioxidant activity,phenolic content and enzymes activities involved in phenylpropnaoid metabolism during eight days storage at 1℃ were investigated in harvested Chinese bayberry fruit cv."Wumei".The results indicated that fruit decay rate increased,fruit quality and antioxidant activity decreased during storage.Contents of total phenolics,flavonoids and anthocyanin as well as main individual phenolic compounds increased gradually during the initial four days of storage,and then declined promptly during the remainder of storage.Statistical analysis showed a positive linear relationship between total phenolic content and enzyme activity involved in phenylpropnaoid metabolism.Therefore,the changes of antioxidant activity and phenolic content were closely related to phenylpropnaoid metabolism.
