Optimization of yellow pigment extracting conditions from Physalis pubescens L. by response surface methodology
The extraction conditions of yel ow pigment of Physalis pubescens were investigated in this paper, the optimum conditions of single factor experiment were obtained, which contained material liquid ratio 1:7.5, extraction time 1 h, ethanol concentration 85%;and optimal parameters for the response surface methodology were as fol ows, material liquid ratio 1:7.14, extraction time 0.96 h, ethanol concentration 84.75%, and the actual measured value was closed to the predicted value, which showed that the model could better predict the actual situation. The results showed that the material liquid ratio, extraction time and ethanol concentration had the important influence on extraction of the yel ow pigment.
