Floatation

May 20, 2021A floatation (FF) process and a solid phase extraction (SPE) process were synchronously applied to the separation and concentration of ginsenosides from extracts of Panax quinquefolius L. The selectivity and sensitivity for the determination of the ginsenosides were improved. The experimental conditions, including volumes of the sample solutions, pH value of sample solution,
