Abstract
A gradient liquid chromatographic method with evaporative light scattering detection (ELSD) for the determination of 24(R)-pseudoginsenoside F(11) in North American ginseng is described. Samples are analyzed by means of a reverse-phase column (Waters Spherisorb ODS-2, C(18)) using acetonitrile and water under gradient conditions as the mobile phase over 20 min. The evaporative light scattering detector (ELSD) used, was set at an evaporating temperature of 35 degrees C and nitrogen gas pressure of 3.4 bar. The detection limit (S/N>5) of 24(R)-pseudoginsenoside F(11) is 53 ng on column.Entities:
