Abstract: In this study, Schisandra chinesnsis (Turcz) Baill was used as the raw material to extractγ-schizandrin by ultrasound-assisted enzymatic hydrolysis. Single-factor experiments indicated that extraction rate ofγ-schizandrin was greatly affected by hydrolysis temperature, hydrolysis time and enzyme dosage. The optimal extraction conditions were explored by response surface analysis to be hydrolysis temperature of 52.89 ℃, extraction time of 4.04 h, and enzyme dosage of 0.96%. Under the optimal extraction conditions, the extraction rate of γ-schizandrin was up to 0.262%. 

Key words: γ-schizandrin, enzymatic hydrolysis, ultrasound, response surface analysis, high performance liquid chromatography (HPLC)
