Optimal Analytical Conditions for Panax Ginseng Ginsenosides using HPLC and Ginsenosides Content Analysis of Red Ginseng Products and their Raw Materials

The analytical conditions of ginsenosides were optimized using high performance liquid chromatography (HPLC). The optimal analysis conditions were set up from the experiments using different gradient conditions, and the ginsenosides contents of red ginseng products and their raw materials were analysed. Red ginseng contained 0.29% Rg1, 0.82% Rb1, 0.38% Rc, 0.32% Rb2, 0.11% Rd, showing the highest ginsenoside contents. Among the red ginseng products, red ginseng extract showed the highest content. The ginsenoside contents were varied according to the raw material type and product type. Re and Rb1 contents were the highest in most raw materials and products.
