Objective: To observe the effect of compound Jiaogulan Yizhi granules（CJG）for improving memory in mice.Method: Experiments of avoiding darkness

jumping stage and water-maze were conducted in mice.The effect of CJG with three doses（0.83

1.67

5.00 g·kg-1·d-1） on memory of mice was observed.Result: In the avoiding darkness test

compared with the control group

the latency time of CJG（medium and high doses） was significantly prolonged（P<0.05）

the error times and the number of entering the darkroom were significantly reduced（P<0.01）.In the water maze test

compared with control group

the swimming time in CJG high dose group was significantly reduced（P<0.05）

and the number of mice to reach the final destination within 2 min in CJG groups（low

medium and high doses） was significantly increased（P<0.05）.Conclusion: CJG has the effect of improving memory.
