Abstract
A new method for separation and quantitative determination of ginsenosides Rg2, Rf, Rg1 and Re in Panax ginseng, Panax quinquefolium and in pharmaceutical drug preparations with HPLC was elaborated. μPorasil column using n–heptane–n–butanol–aceto–nitril–water (1000:446:132:36) as mobile phase was employed. The ginsenosides were separated in 40 min.
A reversed–phase–system with a μBondapak C18 column using methanol–water (440:560) as eluent was suitable for the separation of ginsenoside Rg1. The reversed–phase–system is adoptable for routine analysis of Ginseng extracts. The detection limit for Rgt with the spectrophotometer LC–55 (Perkin–Elmer) was at 207 nm 300 ng at a signal–to–noice ratio of 10:1.
The relative standard deviation is depending from the content of ginsenosides. For ginsenoside contents of 1 % it was circa 1 °/o.
