Optimization of Sweet Potato (<i>Ipomoea batatas</i> L.) Chlorogenic Acid Extraction Process and Hypoglycemic Effect Study.

As can be seen from Figure 1 b, the extraction yield of CGA was highest under the condition of a liquid–solid ratio of 30 mL·g −1 , and then it showed a decreasing trend, which may increase the surface area of the ethanol solution and the diffusion rate of CGA.

Significance Test and Variance Analysis of Regression Model In the response surface test, we obtained a quadratic multiple regression equation as follows ( Table 3 ): Y = −2.8524 + 0.0060A + 0.0215B + 0.1791C + 0.0010AB + 0.0003AC − 0.0001BC − 0.0009A 2 − 0.0006B 2 − 0.0014C 2 Based on the results in Table 4 , the results indicate that the p -value of the model was less than 0.01, indicating that the regression equation was highly significant.
