- W1996395429 abstract "Good manufacturing practice (GMP)-based quality control is an integral component of the common technical document, a formal documentation process for applying a marketing authorization holder to those countries where ginseng is classified as a medicine. In addition, authentication of the physico-chemical properties of ginsenoside reference materials, and qualitative and quantitative batch analytical data based on validated analytical procedures are prerequisites for certifying GMP. Therefore, the aim of this study was to propose an authentication process for isolated ginsenosides <TEX>$Rb_1$</TEX> and <TEX>$Rg_1$</TEX> as reference materials (RM) and for these compounds to be designated as RMs for ginseng preparations throughout the world. Ginsenoside <TEX>$Rb_1$</TEX> and <TEX>$Rg_1$</TEX> were isolated by Diaion HP-20 adsorption chromatography, silica gel flash chromatography, recrystallization, and preparative HPLC. HPLC fractions corresponding to those two ginsenosides were recrystallized in appropriate solvents for the analysis of physico-chemical properties. Documentation of the isolated ginsenosides was made according to the method proposed by Gaedcke and Steinhoff. The ginsenosides were subjected to analyses of their general characteristics, identification, purity, content quantitation, and mass balance tests. The isolated ginsenosides were proven to be a single compound when analyzed by three different HPLC systems. Also, the water content was found to be 0.940% for <TEX>$Rb_1$</TEX> and 0.485% for <TEX>$Rg_1$</TEX>, meaning that the net mass balance for ginsenoside <TEX>$Rb_1$</TEX> and <TEX>$Rg_1$</TEX> were 99.060% and 99.515%, respectively. From these results, we could assess and propose a full spectrum of physicochemical properties for the ginsenosides <TEX>$Rb_1$</TEX> and <TEX>$Rg_1$</TEX> as standard reference materials for GMP-based quality control." @default.
