ABSTRACT
Objective To study the optimization of extraction technology for total flavonoid-aglycone from Scutellaria baicalensis after enzymatic hydrolysis. Methods With three factors of alcohol concentration, dosage and speed of percolation as the indexes, orthogonal experiment was performed. Concentrations of Baicalein, Wogonin and oroxylin-A were analyzed by HPLC. Results The optimal extraction technology is A2B3C2 extracting the medical material by 10 times(V) 95 % alcohol, the speed being 6 mL/kg per min. Conclusion Under optimal extraction technology, extraction rate of total flavonoid-aglycone is very considerable and the concentration is high to 60 % .
