超声辅助提取鱼腥草中芦丁的工艺优化

Optimization of Ultrasonic-Assisted Extraction Process of Rutin from Houttuynia Cordata Thunb.

以提取时间、提取温度和甲醇体积分数为考察因素,以提取液中芦丁含量为考核指标,通过单因素实验和正交实验优化鱼腥草中芦丁的超声辅助提取工艺。结果表明,各因素对芦丁含量的影响顺序为提取温度>甲醇体积分数>提取时间,最优提取工艺为:提取时间30min、提取温度60℃、甲醇体积分数60%。

Using extraction time,extraction temperature and methanol volume fraction as factors,and rutincontent as an index, the ultrasonic-assisted extraction process of rutin from Houttuynia cordata Thunb. wasoptimized by single factor experiment and orthogonal experiment. The order of three factors affecting extractioncontent was extraction temperature methanol volume fractiong extraction time, and the optimal extractioncondition was obtained as follows extraction time 30 min, extraction temperature 60 ℃, and methanol volumefraction 60 %.
