| Abstract: | Foam floatation-solid phase extraction was applied to the separation and enrichment of ginsenosides from extracts of Panax notoginsen(Burk.) F.H.Chen.The selectivity and sensitivity for determining the ginsenosides were improved.The experimental conditions,including the flow rate of nitrogen gas,floatation time and pH value of sample solution,for foam floatation and elution conditions for SPE were examined and optimized.Average recoveries for protopanaxdiol(PPD) ginse-nosides Rc,Rb2,Rb3,Rd,and Rb1 were betw... |
