Abstract
In this paper the factors, which affect the extraction rate, were investigated, the optimum conditions for extraction of polyphenol from lotus root were obtained by orthogonal tests as follow: pH 3, extracting times 3, liquid material ratio 1:9, 40 % ethanol. Under this condition the extraction rate was 0.77 %.
