摘要
研究了以紫甘薯为原料,利用微波辅助法提取原花青素时提取剂浓度、料液比、微波处理时间等因素对提取率的影响。结果表明,在此最佳实验条件下,即以盐酸的乙醇溶液为提取液,在乙醇的体积分数为50%,料液比(g:mL)为1:70,微波处理70s,所得的原花青素浸提量为0.96mg/g。
Study on the influence of the extraction condition of procyanidin from purple sweetpotato by microwave-assisted,such as the concentration of ethanol, the ratio of sample to extractant and the time of microwave processing. As a result, the optimum extracting condition was that ethanol and hydrochloric acid as the solvent,50% ethanol as the extracting reagent, the ratio of sample to extractant is l：70,exracting 60 s. In this condition, procyanidin extracted reach 1.98 mg/g.
