[Objective] The research aimed to study the optimum extraction technique of flavonoid aglycons from skullcap root by cellulase-assisted extraction method. [Method] The conditions for the extraction by cellulase-assisted extraction method were studied through several single factor tests and the orthogonal experimental design, as an evaluation index of the content of baicalein and wogonin in skullcap root by HPLC method. The cellulase-assisted extraction method was compared with the water-decocting method. [Result] The optimized conditions of cellulase-assisted extraction are as follows: liquid-sold ratio is 10∶ 1, the concentration of cellulase is 25 U/g herbals, pH value is 5.0, extraction temperature is 50 ℃, and extraction time is 7.0 hours. Under the optimal conditions, the extraction rate of baicalein and wogonin reached 175.04 and 28.84 μmol/g herbals respectively, being 6.7 times and 4.8 times as that of the conventional water-decocting method. [Conclusion] Cellulase-assisted extraction method for the flavonoid aglycons in skullcap root was efficient, appropriate and feasible.
