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
