摘要: 以胡柚皮为原料,采用闪式提取技术提取胡柚皮中黄酮类化合物。在单因素试验基础上,采用响应面法对提取溶剂浓度、料液比、提取时间进行优化。结果表明,溶剂体积分数、提取时间、液料比对黄酮提取率的影响比较显著,最佳工艺条件为乙醇溶液体积分数78%、液料比31:1(mL/g)、提取时间95s,由此得到的柚皮黄酮提取率为4.37%。闪式提取法是一种快速有效的柚皮黄酮的提取方法。

Abstract: The peels of citrus Changshan-huyou were used as the raw material to extract flavonoids by flash-extraction technology. Based on single factor experiments, extraction conditions such as solvent concentration, liquid/material ratio, and extraction time were optimized by response surface methodology. The results showed that each of the three extraction conditions affected flavonoid extraction significantly. The optimized conditions were as follows: 78% ethanol concentration, 31:1 liquid/material ratio, and 95 s extraction time, resulting in an extraction efficiency of 4.37% for flavonoids. As a conclusion, flash-extraction is an effective and efficient method to extract flavonoids from peel of Citrus Changshan-huyou.

Key words: citrus Changshan-huyou peel, flash-extraction, flavonoids, response surface methodology
