Com- pared with the model control group, the altered behavioural parameters were attenuated significantly （P 〈 0.05） in the group treated with the flavonoid-rich fraction （100 and 200 mg·kg^-1）, comparable to the group treated with the standard drug, fluoxetine （10 mg·kg^-1）. The flavonoid-rich fraction and fluoxetine improved significantly （P 〈 0.05） the activities of the antioxidant enzymes such as superoxide dismutase and catalase as well as other biochemical parameters such as reduced glutathione, protein, and nitrite in the brain of the stressed rats.
