JIN Su-rong~1,YAO Li-feng~1,LU Wei~1,YU Zuo-ping~2,ZHOU Ming-quan~2,HU Zhong-li~2(1 School of Science,Wuhan University of Technology,Wuhan 430070; 2 Lotus center,Wuhan University,Wuhan 430072,China)  
The optimal condition of polyphenol extraction from lotus leaf by ultrasonic were studied.The effects of action time,ratio of raw materials,solution and extraction times on extraction rate of polyphenol were investigated.The best technical conditions for polyphenol extraction was obtained through orthogonal experiments as follows: ratio of raw materials and solution of 1:14,four extraction times,60% alcohol and extraction period of 15 min.
