利用响应面法优化了微波提取竹节参总皂苷的工艺条件。在单因素实验的基础上,选定料液比、温度和时间3个因素的3个水平进行中心组合实验,建立竹节参总皂苷得率的二次回归方程,通过响应面分析及岭嵴分析得到优化组合条件。研究结果表明:当提取工艺条件为料液比1∶13,提取温度65℃,提取时间4.2 min时,竹节参总皂苷得率达到极大值。该条件下竹节参总皂苷得率预测值为23.94%,验证值为24.19%。 Response surface methodology was used to optimize the conditions of microwave extraction of total ginsenoside. On the basis of single factor experiment, the center combination experiment was carried out at three levels of three factors of feed solution ratio, temperature and time to establish the quadratic regression equation of the yield of total saponins of S. japonicus. Response surface analysis and Ridge ridge Analysis of the optimal combination of conditions. The results showed that when the extraction process conditions for the solid-liquid ratio of 1:13, extraction temperature of 65 ° C, extraction time of 4.2 min, the total yield of Stem Poon polysaccharides reached a maximum. Under this condition, the predicted value of the total saponin of S. japonicus was 23.94%, and the validation value was 24.19%.
