Abstract:

On the basis of one-factor-at-a-time investigations, a 20-run central composite design (CCD) involving in 3 factors at 5 levels was used to provide experimental data for optimizing the utrasonic-assisted extraction of triterpenoids from Schisandra chinensis (Turcz.) Baill by response surface methodology (RSM). The optimum conditions for the utrasonic-assisted extraction of triterpenoids from Schisandra chinensis (Turcz.) Baill were determined to be: ultrasonic frequency 68 Hz, length of extraction 48 min and ethanol concentration 64%. Under the optimized conditions, the experimental yield of triterpenoids was (2.534 ± 0.244)%, which was in good agreement with its predicted counterpart.
