Abstract: The affect of drought stress on Epimedium was researched and the relationship between the quantity change of flavone and protective enzyme was expounded.The quantity of POD,SOD and MDA in Epimedium under drought stress were measured by spectrometer;the total quantity of flavone was measured by UV.The results showed Firstly,with the enhanced drought stress,the activity of POD improved and the quantity of MDA increased;within twelve days,the activity of SOD improved,but after twelve days,the activity of that decreased;the quantity of flavone was at its maximum after two day’s drought,but after four days there was little change.Secondly,According to the research,there lied the ability of anti-drought in Epimedium,but when the activity of SOD decreased under the level of sample,the plant died.Thirdly,the quantity of flavone is related to the incipient anti-drought ability of Epimedium.

Key words: drought stress, POD, SOD;MDA;Epimedium flavone
