RESUMEN
Introduction@#It is important to standardize a tincture prepared from the herb and root of <i>Paeonia anomala<i> L, which is widely used as a sedative in traditional medicine, based on the results of the studies its chemical composition, biological and pharmacological activities. Moreover, there is a need to carry out a quantitative stability testing in order to establish the ability to maintain quality under certain storage condition, shelf-life and to develop suitable packaging information.@*Materials and methods@#Standardization parameters of prepared <i>Paeonia anomala</i> tincture have been evaluated according to WHO guidelines for the determination of crude drug material, plant preparations and finished products technical parameters, along with the Mongolian National Pharmacopoeian (MNP) and Russian XIV Pharmacopoeian methods for tincture. The color of a tincture, dry residue, special density, alcohol content, and microbiological content were determined according to the methods described in MNP. A qualitative analysis of biological active constituents has been evaluated by thin-layer chromatography, the total phenolic compounds were determined by the reaction with Folin Chicalteu reagent and total monoterpene glycosides by the reaction with hydroxylamine in alkaline solution and ferric (III) chloride following spectrophotometric examination, respectively.</br> The stability testing study was performed according to the “General requirements for the stability testing study of drug-active compounds” MNS-6439-2014 using the real-time methods for the standardization parameters of the tincture.@*Conclusions@#The standardized parameters of tincture prepared from the herb and root of <i>Paeonia anomala</i> L. were approved by the National Reference Laboratory for Food Safety analysis. Consequently, the Mongolian pharmacopoeian article on <i>Paeonia anomala</i> tincture was officially permitted under the number ҮФӨ-0327-2017.</br> The stability study of tincture was carried out according to the MNS-6439-2014 by real-time tests for 24 months which provided that the changes in tincture quality were within the permitted limits. Consequently, it can conclude that the storage condition and shelf-time of <i>Paeonia anomala</i> tincture are 2 years under not above 25°С.

RESUMEN
Introduction@#Due to social transition and change of many societal activities in Mongolia, there is an increasing need for pharmaceutical drugs to treat anxiety, stress, fatigue and insomnia. It is considered that medicinal plants used in traditional medicine as sedatives, anti-anxiety and anti-depressive activities could be effective. Our study focuses on exploring optimal methods for preparing tinctures from <i>Paeonia</i> L. genus species, a sedative in Mongolian traditional medicine, and studying their phytochemical compositions.@*Materials and methods@#Root and herb of <i>Paeonia anomala</i> L., grown in Mogod soum in Bulgan province, were used for the study.</br> Prepared herb and root were chopped and sieved into 1 mm, 2 mm, 3 mm, 4 mm and 5 mm sizes. Then from each size of two samples, a set was created with a 1:1 ratio. Finally 40 % ethanol (1:10 ratio with a set) was applied to prepare tincture through a traditional maceration method. The obtained tincture was analyzed for its color, quantity of biologically active compounds, dry residue, and absorption coefficient using an optimal particle size of samples, volume of the extractive liquid and tincture yield.</br> Tincture from the set of herb and root of <i>Paeonia anomala</i> L. was prepared using 3 methods, namely, by the traditional maceration; intensified maceration using the ultrasonic bath processing with 45 kHz at an ambient temperature; constant shaking in a heat of 30o-40oC. @*Conclusion@#The more optimal and effective method for preparing tincture from <i>Paeonia anomala</i> L. has been found to be the ultrasonic bath processing with 45 kHz for 6 h at an ambient temperature. Crude drug mixture of 2 mm sizes with 40% ethanol (where volume absorption coefficient was accounted to be 2.8) was mixed at a ratio of 1:10. In the obtained tincture, total phenols were determined as 0.58±0.003% in gallic acid equivalent and total monoterpene glycosides as 1.96±0.002% in paeoniflorin, which were the highest compared to other methods, indicating the method is the more optimal one.
RESUMEN
Prolonged alcohol consumption causes alcoholic liver damage due to the generation of reactive oxygen species, the accumulation of fatty acids, and an increase in inflammatory cytokines in the liver. In this study, the protective effect of a fruit extract of Paeonia anomala (FEPA) against chronic alcohol-induced liver damage was evaluated in Sprague-Dawley rats fed an ethanol or a control Lieber-DeCarli diet for 5 weeks to induce alcoholic liver damage. FEPA (50, 25, and 10 mg/kg body weight/day) as well as the reference control silymarin (25 mg/kg body weight/day) were administered along with the ethanol diet. FEPA protected against increases in alanine aminotransferase and aspartate aminotransferase in serum and attenuated alcohol-induced increases in triglycerides, tumor necrosis factor alpha, thiobarbituric acid-reactive substances, and cytochrome P450 2E1 enzyme activity in the liver compared with the group treated with ethanol only. Anti-oxidative defenses such as the total glutathione level and glutathione peroxidase activity were increased by FEPA treatment. These results suggest that FEPA exerts protective effects against chronic alcohol-induced liver damage by attenuating hepatosteatosis and pro-inflammatory cytokine production and enhancing anti-oxidative defense mechanisms in the liver.
