Abstract

Ginseng saponins were analysed using reversed-phase high performance liquid chromatography with several columns. The optimum conditions were as following : reverse phase column; Novapak <TEX>$C_{18}$</TEX> ODS column (<TEX>$3.9mm{\times}150mm$</TEX>, <TEX>$5{\mu}m$</TEX>), acetonitrile/water binary mobile phase gradient controller system, solvent flow rate; 1.5 mL/min, and UV (203 nm) detector. The complete separation of ginsenoside <TEX>$Rb_1$</TEX>, <TEX>$Rb_2$</TEX>, Rc, Rd, Re, Rf and <TEX>$Rg_1$</TEX> was achieved within 50 min. The regression coefficients of the calibration curves for seven ginsenosides were 0.98~0.99.
