Optimization of Salidroside Extraction with Hot Reflux by Response Surface
摘要
Abstract
[Objective]To establish a rapid, accurate, simple and economy extraction method for salidroside. [Method] With root of Rhodio-la sachalinensis as raw material and distilled water as solvent, hot reflux extraction method was adopted to obtain salidroside. Effects of extraction temperature, time, solid-liquid ratio, extracting times and sample particle, diameter on extracting salidroside from R. sachalinensis were studied. On the basis of single-factor experiment, the extraction technique of salidroside was optimized. And response surface together with contour were firstly graphed with extraction rate as the response value, the significance and interaction of each factor were analyzed. [Result] The optimum technique conditions were: extraction temperature 60. 3 t, time 101 min, solid-liquid ratio 1:21 g/ml, 1 time, the extraction rate was up to 4.21 %. [ Conclusion] The study provides a theoretical basis for industrialization production of salidroside from R. sachalinensis.关键词
