Optimization of Extraction Technology for Total Phenolic Acids from Fruits by Central Composite Design-response Surface Methodology
Objective: To optimize extraction process of total phenolic acids in Capparis spinosa fruits. Method: Independent variables were ethanol concentration
solvent amounts and extracting time
dependent variable was yield of total phenolic acids
levels of independent variables were regressed multiple linearity and fitted by binomial
response surface methodology was used to optimize extraction process
then compared both of observed and predicted values. Result: Optimum extraction progress was as follows:extracted 2 twice with 15 times the amount of 70% ethanol for 1 h per time;yield of total phenolic acids was 7.29 mg·g-1
whose deviation was 0.68% by comparing with the predicated value(7.34 mg·g-1). Conclusion: This optimized process was simple with high precision and good predictability.
