摘要: 本文以脱脂大麦粉为原料,采用超声技术,研究了超声时间、乙醇浓度和料液比三个因素的影响并进行响应面实验设计。经响应面优化确定大麦中总多酚和原花青素的超声最优提取条件为:乙醇浓度65%,超声时间10min,料液比1:27,在此条件下总多酚的提取得率为3.05mg/g,原花青素的提取得率为1.18mg/g。

Abstract:  The defatted barley powder was used as primal material. Effects of ultrasonic time, concentration of ethanol and ratio of liquid to material on extraction yield were investigated by using ultrasonic technology, and then the experiment of response surface analysis(RSA) was designed. The optimum extraction conditions for barley total polyphenol, and proanthocyanidin after RSA were established as follows: 65% ethanol(V/V)as solvent, ratio of solvent to material 27:1(V/W) and ultrasonic time 10min with the yield of total polyphenol 3.05mg/g, and the yield of proanthocyanidin 1.18mg/g.
