Abstract
Objective: The optimal condition of polyphenol extraction from lotus leaf by microwave was studied. Methods: The effects of single fectors, such as microwave treation time, microwave power, ratio of raw materials to liquid, percent of ethanol volume was investigated. Results: The best technical conditions for polyphenol extraction was obtained through orthogonal experiments as follows: ratio of raw materials and solution of 1∶60, microwave power as 300 W, 20% alcohol and extraction period of 150 s.
