超声波辅助提取芦笋老茎中芦丁工艺的优化
Optimization of ultrasonic-assisted extraction of rutin from old stems of asparagus
摘要
Abstract
[Objective]Ultrasonic-assisted extraction of rutin was optimized from the old stems of asparagus in order to provide references for production application of extracting rutin using ultrasonic. [Method]Effects of temperature, time, and concentration on extraction rate were experimented, and optimum parameters for rutin extraction were obtained using orthogonal design. [ Result ] Optimal parameters of ultrasonic-assisted extraction were as follows: the ultrasonic power 90 W, ethanol concentration 60%, optimum temperature 80℃, and the ratio of material to liquid 1:25 (g/mL). Under the best conditions, extraction rate of rutin was 4.53%, the average recovery rate 99.53-100.48%, and coefficient of variation was 1.36%. [Conclusion]Ultrasonic-assisted extraction was workable because of the high recovery rate and good precision.关键词
