Abstract:
BackgroundPanax ginseng is one of the most important medicinal plants in Asia. Triterpene saponins(ginsenosides) are the main bioactive compounds in P.ginseng. The present study investigated thegrowth characteristics of ginsenoside content in the leaves and roots of Panax ginseng at differentgrowth stages (from 1 and 4 years). Analysis was P.ginseng leaves and roots indicated the presenceof two ginsenosides (Rg1 and Rb1) content of Rg1 was higher than Rb1.Aim: The main aim of this study was determine by high performance liquid chromatography (HPLC)ginsenoside Rg1 an Rb1 of P.ginseng grown in Mongolia.Materials and MethodsLeaves and roots of different ages of P.ginseng were collected at October of 2015 in field of Umnugoviprovince, Mongolia. Collected samples were dried and powdered. Samples were extracted with70% EtOH, water saturated butanol and methanol. The extract was filtrated through filter paper(whatman No.42) and evaporated vacuum rotor. The evaporated extract was resuspended with theMethanol. It stored in room temperature and resuspended mobile phase use for HPLC analysis.The two ginsenosides were analyzed using HPLC system of a model (DGU-20A3r Shimadzu) andcolumn was Octadecylsilane 5μm I-150mm, D-4.6mm, detector was UV 204 nm. The sample wasinjected (20μl) and applied gradient elution was as follows British pharmacopeia.ResultsGinsenosides levels were much higher in the 4 ages roots compared with the 1 ages roots.Ginsenoside amounts in P.ginseng organs changed depending on the specific time during thevegetation season the samples were taken. This study found that the highest content of thesemetabolites-2.082% (butanol extract) occurred in the roots. Our study was independently of thevegetation season. These were Rb1 and Rg1, with values Rg1 was 0.7-2.082% and Rb1 was 0.002-0.03%.ConclusionGinsenosides are generally distributed throughout all the parts of the ginseng plant. We found thatthe highest Ginsenoside Rg1 content accumulated during the first year of growth then decreaseduntil four year.
