ABSTRACT
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.

ABSTRACT
Introduction@#Plant species of Pedicularis L., one of the largest genera of the Scrophulariaceae family, is found in cold regions of Asia, Europe, and America. In ancient Chinese, Tibetan, and Indian medicinal literature, it is noted that due to the detoxification potential of Pedicularis L., it has been used for reducing and curing of edema, fever, inflammation and poisoning. In the recent studies, species of Pedicularis L. have been determined to possess anti-oxidative, antitumor, antibacterial, antifatigue and, analgesic activities, as well as muscle relaxant, hepatoprotective effects. From this genus, more than 230 constituents, mostly belonging to the phenylpropanoids, iridoids, lignans and their glycosides have been isolated and identified.@*Material and method@#In this review, we reviewed 80 papers on the genus Pedicularis L. which were published in scientific journals from 1963 to 2018, using databases such as Springer Link, Google Scholar, Pub Med, Elsevier, Research Gate. In addition, literatures on Mongolian medicinal plants and herbal medicines have been used, where the taxonomy, morphology of Pedicularis L. and their usage was described.@*Conclusions@#As this survey, less than 10 percent of the 600 species of Pedicularis L. has been studied for their phytochemical constituents and biological activities. More than 230 compounds including phenylpropanoids, iridoids, lignans, flavonoids, alkaloids and other classes of constituents have been isolated and their molecular structures were identified. Among them, 67 compounds or 30 percent were natural new compounds. Anti-oxidative, antibacterial, antitumor and, muscle relaxant activities of the Pedicularis L. related to the quantities and structural peculiarities of phenylpropanoid glycosides, iridoid glycosides, and flavonoids. Especially, phenylpropanoid glycosides are more interesting as they demonstrate wide range and much higher biological activity compared to other classes of compounds. Therefore, future research will focus on chemistry and biological activity of this class of compounds.
ABSTRACT
The dichloromethane fraction from the ethanol extract of the aerial parts of Taraxacum offi cinale showed a good inhibitory effect on hepatocellular carcinoma cells (HCC). As a result of a series of column chromatographies and usage of nuclear magnetic resonances spectrometric methods and mass spectroscopy 9 known components as taraxasterol (1), taraxasterylacetate (2),pseudotaraxasterol (3), lupeolacetate (4), b-sitosterol (5), b-sitosterylglucopyranose (6), palmitic acid (7), monopalmitin (8) and chrysoerol (9) have been determined. Amongst them palmitic acid, monopalmitin and chrysoeriol have been determined for the fi rst time in the aerial parts of Taraxacum offi cinale. Six compounds as 1, 3, 4, 5, 6 and 7 were tested for their inhibitory activity on HCC and only palmitic acid exhibited more activity against HCC than others, suppressing cell proliferation, migration, adhesion and activated cell apoptosis.Keywords: Triterpenol and sterol derivatives; palmitic acid; hepatocellular carcinoma inhibition activity;IntroductionTaraxacum, commonly called dandelion, is a large genus of fl owering plants in the Asteraceae family. The latin name Taraxacum is from the Greek and means “disease remedy”, while the English name dandelion is originated from the French dent de leon, meaning “lion’s tooth”1. The Mongolian well-recognised name is “baaban beeben”, while in Japan it calls hokouei, respectively. Consequently, Taraxacum is widespread plant throughout the world, in particular, 19 species are found in the Mongolian fl ora2. Generally Taraxacum is considered weedy plant used as a medicinal herb and for food preparation. Traditionally, Taraxacum offi cinale Weber ex Wigg. in Mongolian and Tibetan medicine under the name “khurmong” the root has been used as the composition in a remedy for jaundice and other disorders of the liver and gallbladder, whilethe leaf is used as a diuretic and bitter digestive stimulant. Moreover, fresh dandelion stem latex is used for the warts treatment1,3-6. Taraxacum leaf is included as a medicinal drug in Herbal Pharmacopeia of several European countries. Numerous biological activity tests resulted that Taraxacum possessed an infl ammation modulating activity7-9, diuretic activity comparable to furosemide10, digestive stimulant, appetitive effect and activator for bile fl ow11-12, hypoglycemic activity13 and antitumor activity14. No side effects and carcinogenicity of T. offi cinale extracts and preparations have been noticed. Chemical constituents of T. offi cinale arewell studied. Scientists of different countries reported that whole plant T. offi cinale containedabundance of bitter principles as terpenoids and sterols, bile like terpenes and sterols, various fl avonoids and phenolic acids, large amount of polysaccharides as inulin and fructosans11,15-17.Also, dandelion is a rich in minerals such as iron, potassium and zinc18,19. In this work we are describing activity-guided isolation and the molecular structure elucidation of components from the dichloromethane fraction of the aerial parts of T. offi cinale, from the Mongolian fl ora.
ABSTRACT
Aims: To investigate the Mongolian plant M. mohileviensis Down. for the presence of possible bioactive products that could be related to the traditional use of the plant in Mongolia. Methodology: Ethanolic and water extracts of both seeds and herb were tested for antiinflammatory and DPPH scavenging activity. Polysaccharides were isolated from the seeds using sequence of chromatographic methods. The polysaccharide fraction from the cold water extract was then analyzed for the presence of monosaccharides and their type of linkages by GC and GC-MS. The effect of the polysaccharides on the complement system was then determined. Results: The ethanolic and aqueous extracts of seeds and herbs, as well as crude polysaccharides from cold and hot water extracts exhibited a significant anti-inflammatory activity in the model based on histamine-induced paw edema. Anti-inflammatory effects of all samples were high during the 3rd hour of inflammation. Moreover, the ethanolic extracts of seeds and herbs exhibited DPPH scavenging activity. Phytochemical studies of the cold water seed polysaccharide revealed the presence of an uncommon pectic type polysaccharide. Galacturonic acid (38%) and rhamnose (30%) were present as the main monosaccharides, and linkage analyses revealed that galacturonic acid was present as terminal, 14 and 13,4 linked units and rhamnose basically as 13 linked units. The complement fixation activity was appr.15 μg/ml, substantially lower than that of the standard used. The results also indicate strongly that the M. mohileviensis and M. verticillata are two different Malva species.
