Open publisher page 0 citations

Abstract

The quadratic regression rotational combination design with three factors was used to optimize the extraction process of flavonoids from lotus leaves with extraction rate as the evaluation index. Through the combination optimization of different factors with computer,the optimal ranges of three factors affecting flavonoids extraction from lotus leaves are confirmed as follows:temperature 71℃ to 74℃,time 1.6 to1.9 h,and ratio of material to liquid 1:39 to1:44. The interactive effects different factors were also studied. The results would provide technical basis for flavonoids extraction from lotus leaves.
