Title: Response Surface Methodology as an Approach to Optimization of Flash-extraction of Flavonoids from Peel of Citrus Changshan-huyou
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 condi-tions 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.
