Study on the extraction technology of baicalin

Objective: To define the optimal parameters of extracting with water, depositing with acid, washing with water and ethanol in the extracting of baicalin from scutellaria. And to supply a reference for the extraction and purification of baicalin in future. Methods: Using the content of baicalin as an assessing index,the optimum extracting conditions which were about extracting with water, depositing with acid,washing with water and ethanol were selected by orthogonal design and the analysis of variance. Results: The optimum extracting conditions of baicalin were selected. Conclusion: The extraction technology is reasonable ,the yield of baicalin is high, and the quality is easily controlled.
