Abstract:
Taking Mirabilis jalapa seed epicarp as material，using response surface methodology (RSM)，based on single factor experiments，the effect of extraction temperature，extraction temperature，liquid-to-solid ratio and ethanol concentration on extraction content of total phenol were investigated，and the significance of the various factors and interactions were analyzed.The results showed that the optimal extraction conditions were extraction time of 46 min，extraction temperature of 62℃，liquid-solid ratio of 23∶1 mL/g and ethanol concentration of 75% (V/V).Under the optimization extraction conditions，the experimental yield of total phenol obtained was 4.41 mg/g.The established regression equation for total phenol extraction had an excellent fit，which was credible and can be used for practical prediction.
