 Title    HPTLC-Analyse von Ginsenosiden zur Bewertung von Ginseng-Extraktionen mit Methanol-Wasser, Wasser oder Ammoniak HPTLC Analyses o f Ginsenosides for the Evaluation of Ginseng Extractions with M ethanol-W ater, W ater or Am m onia  
 Abstract    Korean Ginseng roots were extracted with m ethanol-w ater, water and liquid and supercriti­ cal ammonia. The yields of the extracts by different methods are reported. The extracts were analyzed by high-performance thin-layer chrom atography. Retention value factors of ginsen­ osides are tabellized. The absolute yields have been measured in mg ginsenoside per g ginseng root for the used standard ginsenosides. Formally the am m onia extraction at 334 K and 26 bar is found to be favourable. The supercritical condition of 418 K and 130 bar leads to a decom­ position of the ginsenosides. Possibilities of fractionation by different solvents or different temperatures are indicated, but attem pts are still required to get fractions o f several extraction agents.
