Optimization of Extraction Technology for Volatile Oil from Shentong Zhuyu Decoction by Central Composite Design and Response Surface Methodology
Objective: To optimize extraction technology of volatile oil from Shentong Zhuyu decoction. Method: With microwave power
liquid-material ratio and extraction time as independent variables
yield of volatile oil as dependent variable
multiple linear regression and binomial of each level of independent variables were fitted. Optimum technology was selected by central composite design and response surface methodology
and prediction was carried out through comparing the observed and predicted values. Result: Optimum extraction technology parameters were as follows: microwave power 266.77 W
liquid-material ratio of 7.29∶1
extraction time 4.215 h. Under this conditions
maximum estimated value of volatile yield was 1.06% which was agreed with model predicted value. Conclusion: Optimized extraction technology was simple
