Abstract: In order to promote the rational utilization of gooseberry resources,the"Zhuiyu"of Ribesiaceae was taken as experimental material,the changes of length of longitudinal diameter and transverse diameter,content of titratable acid,flavonoids and antioxidant activity in vitro were determined.The results showed that the content of titratable acid increased with the growth and development of gooseberry fruit.The content of flavonoids in fruits decreased gradually with fruit ripening.The gooseberry fruit had strong antioxidant activity（DPPH,FRAP and·OH）in vitro.Correlation analysis showed that the content of flavonoids in gooseberry fruit was extremely significant positive correlated with DPPH free radical scavenging ability（P＜0.01）,and FRAP radical scavenging ability was significantly positive correlated（P＜0.05）.The correlation between flavonoid content and·OH free radical scavenging ability was the weakest.
