Orthogonal Test on Extracting Technology of Baicalein of Scutellaria baicalensis
Abstract:ObjectiveTo optimize the extract conditions for baicalein of Scutellaria baicalensis. MethodsThe orthogonal design with three levels of four factors including solvent , extracting time , extracting methods and extracting times were adopted , the contents of baicalein were determined by RPHPLC. ResultsThe optimum extracting conditions were A2B1C2D3 , that was cold-maceration, water as the solvents and to extract for 90 min and totally for 4 times .ConclusionThe solvents greatly influenced the extraction of baicalein . The extract technology of baicalein is feasible and reasonable .
