[Studies on optimizing extraction technics of flowers of Polygonum orientale by response surface methodology]
Objective:
To analyze and optimize extraction technics of Polygonum orientale flowers by response surface methodology.
Methods:
With the index for the content of taxifolin in flowers of Polygonum orientale, the effect of three factors such as concentration of alcohol, extraction time and solvent-solid ratio was designed by Box-Behnken central composite. Extraction technic parameters of Polygonum orientale flowers was optimized by response surface methodology.
Results:
The optimizing extraction conditions of Polygonum orientale flowers were as follows: ethanol concentration was 65%, extracting time was 129 min and solvent-solid ratio was 18. Under the conditions, the average yield of taxifolin in 3 validation experiments was 2.79 mg/g.
Conclusion:
Optimizing extraction technics by response surface methodology is reasonable, simple, and has good predictability.
