ABSTRACT
Objective:
To optimize the extracting process of total flavonoids from Gynostemma pentaphyllum.Methods:
The total flavonoids were extracted with ethanol 95% after the cellulose treatment to G. pentaphyllum, and the effects of enzyme dosage, enzymatic treatment temperature, enzymatic treatment time, and pH value on the total flavonoids yield was studied with response surface method.Results:
The optimal enzymatic extracting process of total flavonoids was as follows enzyme dosage 120 U/mL, enzymatic temperature 49 °C, enzymatic time 150 min, and pH value 3.9, and the total flavonoids yield reached 0.357%.Conclusion:
Cellulase is suitable for the total flavonoid extraction from G. pentaphyllum.
