摘  要:
为充分提取中国苦荞麦壳中的活性多酚,以70%乙醇-水为提取剂,通过二次旋转正交试验优化提取工艺,建立了提取得率的二次旋转回归方程,通过响应面分析及岭嵴分析得到了优化组合条件。结果表明,提取温度和时间对提取得率有显著影响(P<0.05),而料液比对提取得率的影响不显著,较优的提取工艺条件为提取温度73℃、提取时间118.9min、料液比1:16.9,其提取得率0.56%,理论预测值为0.59%,提取得率达到理论预测值的94.9%。

摘  要:
Procyanidins in buckwheat shells was extracted with a mixture of 70% ethanol and water.In order to maximize the extraction of procyanidins,a rotatable orthogonal central composite design combined with response surface and ridge analyses was employed.Extraction temperature and time affected the yield of procyanidins significantly(P < 0.05),while the effect of ratio of material to liquid was not significant.The optimum extraction conditions were as follows:ratio of material to liquid 1:16.9,temperature 73 ℃,and extraction time 118.9 min.Under these conditions,the actual yield of procyanidins was 0.56%,which accounts for 94.9% of the theoretically predicted value of 0.59%.
