响应面法优化超声辅助提取苦荞壳总黄酮工艺
Optimization of ultrasonic -assisted extraction of total flavonoids from tatary buckwheat shell by response surface methodology
摘要
Abstract
Response surface methodology was applied to achieve the optimal conditions of ultrasonic -as-sisted extraction of total flavonoids from tatary buckwheat shell.Base on single factor experiments,ultra-sonic power,extraction time,temperature and liquid -solid ratio were chosen as influence factors on the yield of total flavonoids according to the principle of Box -Behnken central composite design.60% (vol-ume)alcohol was used as an extraction solvent,the results showed that the optimal extraction conditions were ultrasonic power of 50 W,extraction time of 26 min,extraction temperature of 53 ℃,liquid -solid ratio of 49 mL g -1 ,and extraction times of 2.Under the optimal conditions,the extraction rate of total flavonoids was 2.02 %.The optimal extraction conditions were reasonable and reliable,which provided technical support for the utilization of total flavonoids from tatary buckwheat shell.关键词
