摘要:

对葛根总黄酮进行超声微波双辅助萃取研究。以总黄酮提取率为考察对象,研究固液比、微波功率、微波辐射时间、作用次数、乙醇体积分数5 个单因素对葛根总黄酮提取率的影响。结果表明:采用超声微波双辅助萃取技术得到的总黄酮提取率较单独采用超声或微波辅助得到的总黄酮提取率高。在以50% 的乙醇为提取溶剂、固液比1:25(g/ml)、超声处理30min、微波功率700W、微波时间40s、间歇处理3 次的条件下,得到总黄酮提取率最大为85.69%。

Abstract:

Radix pueraria was used as raw material to optimize flavoniods extraction with the aid of microwave and ultrasonic technology. Effects of solid-liquid ratio, microwave power, microwave duration, microwave treatment repeat times, alcohol concentration on extraction rate of flavonoids were evaluated through orthogonal experiments. Results showed that the optimal extraction condition was 30 min of initial ultrasonic treatment, 700 W microwave power, 80 mesh of grinding degree, 40 s of microwave duration, 1:25 of solid-liquid ratio, 50% alcohol, and three times of microwave repeat treatment. Extraction rate of flavonoids from Radix pueraria was 85.69% under this optimal condition.

Key words: Radix pueraria, ultrasonic extraction, microwave extraction, flavonoids
