  • Study results of the acquired data on Tribulus terristris L. extraction
           technology parameters

    • Authors: Baigalmaa D, Enkhjargal D, Wang Qin Hu
      Pages: 83 - 86
      Abstract: It has been noted in the Mongolian traditional medicine sources that aerial parts, fruits and seeds of the Tribulus terestris L. plant are beneficial for renal diseases and improvement of renal function. In the current marketplace, herbal medicinal products for sexual potency and their production have been developing rapidly. Therefore, with the goal of appropriate usage of national resources and to provide a substitute for the imported products, a technological study on the extraction of liquid extracts from the upper part of the Tribulus terrestris L. plant was carried out. In the first part of this herbal tablet development technology research the appropriate solvent concentrations for the extraction from the plant raw materials, which are the main technological indicators, were determined by the total saponin concentrations in the plant by spectrophotometric method. As a result of the study the ideal extracellular solvent for extraction was determined, a 70% ethanol and the total saponin content was 15.53 mg/ml or 0.77%. Зэлэн зангуу ургамлын (Tribulus terristris L.) шингэн ханды технологийн зарим үзүүлэлтийг тогтоосон судалгааны үр дүнгээс Хураангуй: Монголын УАУ-ны эх сурвалжуудад Зэлэн зангуу ургамлын (Tribulus terristris L.) газрын дээд хэсэг, үр жимсийг нь бөөрний өвчинд тустай, бөөрний тамир сайжруулдаг хэмээн эмийн үйлдлийг нь тэмдэглэн үлдээсэн байдаг.

  • Diterpenoid alkaloids from Aconitum and Delphinum species

    • Authors: Batsuren D, Batbayar N, Tunsag J
      Pages: 3 - 9
      Abstract: Since 1986 we started investigating diterpene alkaloids from Aconitum and Delphinum species in Mongolia. Alkaloid composition of some 12 species of Aconitum and Delphinum of Ranunculaceae family and 63 individual compounds were isolated and identified. Among them 9 were newly found naturally-occurring compounds and structure of these alkaloids were elucidated completely. High resolution Mass-spectrometry, 1H and 13C NMR, 2D NMR techniques such as COSY, HMQC, HMBC were employed to elucidate structure of new compounds. Structure of altaconitine was elucidated and confirmed by applying X-ray crystallographic analysis in addition to above- mentioned techniques. As a result of our long-term chemical in-vestigation of plant species of Mongolia, we have observed and established that secondary metabolites such as alkaloids, coumarins, lignans and xanthones accumulate in more oxidized form in plant species grown in Mongolia. This principle is also demonstrated in the structure of diterpenoid alkaloids isolated from plants of Ranunculaceae family grown in Mongolia. As can be seen from alkaloids 11-acetyl-1, 19-epoxydenudatine and turpelline each contain 4 oxygen atoms, which is more oxygen atoms than in commonly-occurring C-20 diterpenoid alkaloids. Except turpelline no other C-20 alkaloid containing four hydroxyl groups was found in nature. Altaconitine is a newly discovered alkaloid which contains functional groups with highest number of oxygen atoms among C-19 diterpenoid alkaloids. Ring “A” in altaconitine structure is substituted at C-1, C-2 and C-3 positions with 2, 3-transdiol system, making altaconitine a unique structure found in nature.

      Pages: 10 - 20
      Abstract: The detailed phytochemical study of Mongolian medicinal plants started in 1973, when a Department for a study of physiologically active substances chemistry was established in the Institute of Chemistry, Mongolian Academy of Sciences. We had studied alkaloids of 30 medicinal plant species grown in Mongolia for the first time. According to the study, 320 alkaloids had been isolated and their molecular structures were identified. Among them, 34 alkaloids had been established as natural new com-pounds and all results of the investigation were published in peer-reviewed international journals. Some biological activities of total alkaloids and certain individual compounds had been studied. In accordance with phytochemical and biological activity studies, several products, the cattle weight gain preparation “Targa”, the preparation for the uterus smooth muscles contraction “Alkum”, the anti-diabetic preparation “Dentamon-10”, the expectorant “Stelleriaphytin”, the liver protective and immune-active preparation “Barbadin”, had been obtained on the basis of collaborative work and the products had been introduced in the market.

  • Medicinal plants - Therapeutic effective compounds

    • Authors: Odontuya G
      Pages: 21 - 28
      Abstract: In plants, substances starting with a simple skeleton to highly complex chemical structures having specific activities are synthesized. Plants are still considered a resource of valuable raw materials for producing different therapeutic and health supporting products, as well as a pool of significant pharmacological active compounds. According to the analysis of the recent PubMed research trends, it was observed that the number of scientific research interest targeting plant-derived natural products had increased. New approaches for discovery of medicinal plants, isolation, identification and characterization of secondary metabolites, and resupply of plant-derived natural products are being developed. Meanwhile, the usage of medicinal plants and plant-derived natural products for any disease conditions is being increased worldwide. There is a limited possibility to isolate therapeutically active compounds from natural-originated plants and resupply them in the market. Therefore, alternative resupply approaches are being developed that they rely on biotechnological products and chemical synthesis. Currently, the research on medicinal plants and plant-derived secondary products is going with success using a broad interdisciplinary approach of chemical and biological sciences involving advanced technologies. Medicinal plants are a source of therapeutically active compounds and new drugs, and other health supporting products.

      Abstract: Monoammonium glycyrrhizinate of Glcyrrhiza root has been used as an expectorant, detoxificator, anti-allergic, and antioxidant. Japanese researchers have been determined its anti-hepatitis A, B, C, D viruses activity. Therefore, we isolated mono-ammonium glycyrrhizinate from Glycyrrhiza root, grown in Mongolia and developed controlled release matrix tablet. Appropriate excipients were chosen for matrix tablet: lactose as a diluent, 5% of PVP-K30 as a binder, HPMC as a matrix former, 3% of talc and 1% of magnesium stearate as a glidiant or lubricant. We prepared matrix tablet by wet granulation method and pressed by 2.5 kPa pressure. Formulation 5 (F5) was determined the most qualified tablet design and it released drug constantly in vitro. For the determining of hepatoprotective effect, we studied influence on hepatocytolis of preparation in vivo by the histological method. Results of the study showed that the Licozinat matrix tablet was appropriate at a 52 mg/kg dose once daily.

  • Chemical transformation of diterpenoid alkaloids

    • Authors: Ganbaatar J, Batsuren D
      Pages: 35 - 41
      Abstract: The diterpenoid alkaloids, with an intriguing chemistry and numerous varied bioactivities, constitute the largest and most complicated group of terpenoid alkaloids. The diterpenoid alkaloids, isolated mainly from Aconitum and Delphinium species (Ranunculaceae), have been of great interest since the early 1800 because of their pharmacological properties. Extracts of Aconitum species were used in ancient times for treatment of gout, hypertension, neuralgia, rheumatism, and even toothache. Extracts have also been used as arrow poisons. Some Delphinium species are extremely toxic and constitute a serious threat to livestock. Delphinium extracts also manifest insecticidal properties. In the past 30 to 40 years, interest in the diterpenoid alkaloids has increased because of the complex structures and interesting chemistry involved. In this review, we summarize recent progress on the chemical transformations of diterpenoid alkaloids.

      Abstract: Essential oil plants have been used for a long time in traditional medicine. Rhodiola rosea L., also called “roseroot”, is a common member of the family Crassulaceae, known as one of the most important popular medicinal plants in the northern region of Europe. The roots of R.rosea possess a wide range of pharmacological activities such as antioxidant, antiinflammatory, anti-cancer, cardioprotective, and neuroprotective effects that are because of the presence of different phytochemicals such as phenols and flavonoids. The chemical composition of essential oil from R.rosea was determined by GC/MS analysis. The essential oil of R.rosea mainly consists of oxygenated monoterpenes (83.38 %). The chief components of the oil were geraniol (25.93 %), myr-tenol (14.94 %), octanol (13.71 %) and (E)-pinocarveol (11.07 %).
      Antioxidant activity of ethanol extract (root) was evaluated by using DPPH (1,1-diphenyl-2-picrylhydrazine) radical scavenging assay with an IC50 value of 5.84 μg/ml. The cytotoxicity was measured using the MTT assay. The ethanol extract of R.rosea pre-sented toxic activity against A-431 (51.80%) human epidermoid carcinoma cell line.

Зайдсанд гахайн өөхийг багасгаж шаараар орлуулснаар тослогийн агууламж, илчлэг чанар буурсан. Түлхүүр үгс: пивоны шаар, арабиноксилан, тослогийн агууламж
