Makarova D.L., Hanina M.A., Amelchenko V.P., Domrachev D.V., Tkachev A.V. Chemical study of essential oil of ARTEMISIA PONTICA L. from Siberia Artemisia pontica L. - is a plant, which is growing wild in different regions of the Western Siberia. Aim. To perform chemical study of essential oil of A. pontica. Material for our experiments was collected both in wild regions and under introduction. Raw material are overground parts of A. pontica, collected at different stages of plants development (beginning of growth, budding and flowering) and parts of the plant (flowers, leaves, stems). Methods of investigation: Essential oils were prepared by hydrodistillation (of air-dried plant material) for 5 hours, and then studied by GC-MS. Results. The overground parts of A. pontica contain 0,62-1,56% of essential oil. Maximum essential oil contents in aerial parts of the plant (flowers) is up to 2,3%, minimum - in the stems (0,06%). The maximum occurred at the beginning of flowering (1,56%). All the samples of the oil are blue due to the presence of chamazulene. GC-MS of the essential oil shows up to 200 components. The main components are: 1,8-cineol (up to 70,6%), camphor (up to 27,4%), bornyl acetate (up to 3,9%), vulgaron B (up to 25,2%), chamazulene (up to 18,8%). The maximum of chamazulene content was found at the beginning of growing (18,8%), and during flowering (13,1%). To conclude, the investigation revealed that A.pontica from Western Siberia a perspective plant for using in officinal medicine. Mirovich V.M., Konenkina T.A., Fedoseeva G.M., Golovnih N.N.

BETULONIC ACID REDUCTION TO BETULINIC ACID AT CONDITIONS OF THE PHASE TRANSFER CATALYSIS The present invention relates to improved methods of betulinic acid production from betulonic acid. The betulonic acid has been reduced to betulinic acid with sodium borohydride in the water - organic solvent -quaternary alkyl ammonium salt admixture at room temperature. The optimum ratio between the amounts of betulonic acid – sodium borohydride – quaternary alkyl ammonium salts has been selected. The most affective carries of borohydride-ion transfer from water to organic phase and suitable organic solvents supply the yield of betulonic acid 98,5–99,3%. Arhipova А.V., Malkova K.V., Sokolova T.N., Kartashov V.R. synthesis of α-(1,7,7-TRIMETHYLNORBORNYL)-β-DIMETHYLCARBAMID BY the REACTION OF CAMPHENE WITH DIMETHYLCYANAMIDE IN THE PRESENCE OF molybdenophosphoric ACID In the present work, we studied the possibility of the Ritter reaction to synthesize of various N-substituted amides. This reaction has been usually catalyzed by strong mineral acids such as H2SO4, PhSO3H, MeSO3H, HSO3F, anhydrous HF and some others. For instance, the reaction of camphene with benzyl thiocyanate used in excess in the presence of H3PW12O40 and H4SiW12O40 as catalyst gave the new compound - N-(1,7,7-trimethylnorbornyl)-benzylthiocarbamate. The heteropoly acids are effective catalysts because they are strong Bransted acids. Dimethylcyanamide reacted with camphene in the presence geteropoly acid (GPA) 12-molybdenophosphoric at 60 °С to give α-(1, 7, 7-trimethylnorbornyl)-β-dimethylcarbamid. The yield of dry crystals was 55%. The reactions were carried out in surplus of dimethylcyanamide (camphene : catalyst ratio was 1 : 2,6). Except water and tetrahydrofurane (TGF) were added in the reaction (camphene : water ratio was 1 : 5). The composition of the reaction mixture was monitored by GLC. The structure of receipt compound was determined by mass spectrometry, 1H and 13C NMR spectroscopy by comparing its physicochemical parameters with the known data.

FEATURES OF CURVILINEAR FORM SETS OF DISK MILLS INDIVIDUAL KNIFE CONSTRUCTION In introduction it is spoken about to improve beating process it is possible by a choice of figure knife set. Therefore the problem of curvilinear form individual knife construction is put. For construction are set by the form of a knife. In this case the form district. It is the most simple for manufacturing. According to figure 1 size of a corner β can vary irrespective of a corner α. It is feature of the given kind sets. Entrance parameters are entered. There are external and internal district edge radiuses, entrance angle α and target angle β, coordinates and radius curvature center. Further determine the equation of curvature for an individual knife construction, knife points crossing coordinates with external and internal district edge radiuses and the central corner φ. Proceeding from the received values and taking into account feature knife set determine radius of curvature of an individual knife. It is limited external and internal district edge radiuses, entrance angle α and target angle β. And then it is determined radius curvature center. Thus for the first time the problem of an curvilinear form individual knife set construction is solved in view of the entrance angle α does not depend on a target angle β. Thus there was possible a definition of radius of curvature Rx. Ananina N.A., Andreeva O.A., Oganesyan E.T. Polysaccharides of Dahlia (Dahlia single L.) tubers The paper describes the data on Dahlia single L. tubers polysaccharide extraction and chemical composition. The carbohydrate complex has been found to include water-soluble polysaccharides, pectin substances and hemicelluloses. The qualitative monosaccharide content was determined by paper chromatography. Water-soluble polysaccharide fractions and pectins appeared to be predominant substances in the carbohydrate complex studied. Sufficiently high polysaccharide yield indicates to the prospects of Dahlia single L. tubers application as a source of both inulin and water-soluble polysaccharides and pectins.
