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.
ABSTRACT
IntroductionA hangover is the experience of various unpleasant physiological and psychological effects followingconsumption of alcohol beverages, which can last for more than 24 hours. Common symptoms ofhangover are headache, gastrointestinal complaints, sweating, hyper-excitability, dry mouth, anorexia,diarrhea, dizziness, fatigue and vertigo. Alcohol or ethanol gets metabolized to an intermediate product,acetaldehyde, by the enzyme alcohol dehydrogenase (ADH), and then acetaldehyde is converted toacetate by a second enzyme aldehyde dehydrogenase (ALDH). Acetaldehyde causes toxic effects,such as high pulse, rate, sweating and vomiting. In most people, ALDH metabolizes acetaldehydequickly and effi ciently, so that this intermediate metabolite does not accumulate in high concentrations.Many treatments are described to prevent hangover, shorten its duration, and reduce the severity of itssymptoms, including innumerable folk remedies and recommendations.GoalThis study was conducted to investigate whether anti-hangover preparation has a protective effectagainst acute alcohol induced hangover in Wistar rats.Materials and MethodsMale and female Wistar line rats, weighing 180-210g were used for hangover model or ethanolmetabolism experiment. Rats were administered orally ethanol as 38% aqueous solution with feedingneedle, 1 ml/200g body weight. The anti-hangover preparation was administered 1 hour before ethanolconsumption. Blood was collected from the tail vein for the measurement of serum acetate andacetaldehyde at just before and 8, 16, 24 hour after ethanol administration.Statistical analysis: All value expressed as mean S.E obtained from n number of experiments.ResultFrom this study results summarize that the anti-hangover preparations decreased blood serum acetateand acetaldehyde levels as compared to control. Anti-hangover preparations enhanced acetaldehydeand acetate metabolism.Conclusion: These fi ndings indicate that anti-hangover preparations may exert benefi cial role inthe treatment of alcohol hangover without any toxicity. Therefore, the content of acetaldehyde wasdecreasing and increasing through repeating 8 hours within 24 hours.
