Orthogonal Array Optimization of Ultrasonic-Assisted Extraction of Panax notoginseng Saponin Rgl
摘要
Abstract
The ultrasonic-assisted extraction of Panax notoginseng saponin Rgl was optimized using an L9（34） orthogonal array design based on one-factor-at-a-time experiments. The effects of ethanol concentration, material-to-liquid ratio, ultrasonic frequency and extraction time on extraction efficiency were examined. Ethanol concentration had the highest effect on extraction efficiency, followed by extraction time and material-to-liquid ratio; the effect of ultrasonic frequency was the weakest. The optimal levels of ethanol concentraion, material-to-liquid ratio （ghnL）, ultrasonic frequency and extraction time were 70%, 1：12, 59 kHz and 60 min, respectively. Under the optimized extraction conditions, the extraction yield of saponin from Radix Panax notoginseng was 1.85%.关键词
