Objective:
To optimize the herb processing process for the total contains of psoralen and isopsoralen and the rate of extract in Psoralea corylifolia by micro-wave herb processing.
Method:
The contains of psoralen and isopsoralen was obtained by HPLC. The micro-wave herb processing process was optimized by the way of uniform design and contour map.
Result:
The optimum process was:20% as salt concentration, 4h as immerse time, micro-wave strength as strong, 270 seconds as micro-wave time. The absolute error of the predicted value from the models were smaller than 6% and 0. 3% respectively.
Conclusion:
The regression models are notable and reasonable, which can forecast results precisely.

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
