CONTENTS

Influence of fatty and abietic acids mix in the 50 : 50 ratio and synthetic surface-active substance DC on the mechanism of formation and extraction of residual lignin and pitch from cellulose is investigated during kraft cooking of birch, aspen and mixes of these breeds of wood. It is established, that decrease in the lignin and pitch contents in cellulose is caused by increase of efficiency their diffusion extraction in liquors at a stage of temperature rise from more dense cellular walls of birch wood, than aspen, at separate and joint kraft cooking of birch and aspen chips at the presence of additives.

It was determined by experimentally a capacity of a reiterative using (recycle) to 45% waste liquor in catalytic delignification of wood with hydrogen peroxide. The excess of organic matter may be separated by the ultrafiltration.

Industrial samples of hydrolytic lignins of Segejsky, Bobruisky, Tavdinsky, Siktivkarsky plants are under investigation in this work. The goal of investigation is establishment of chemical composition of extractives of industrial hydrolytic lignins. It is well known from literature that amount of extractives in the industrial samples of hydrolytic lignins could reach a significant part of the sample (up to 20–25% of the sample). That is why it is important to know the chemical composition of such considerable group of substances in order to create a high-grade method of utilization of hydrolytic lignin and to compose representative knowledge about this industrial by-product. GCMS, FTIR, MWD, TLC were employed in the work.

The major groups of extractives are terpens, destruction products of monosaccharides, organic acids, monosaccharides, aliphatic hydrocarbons, aromatic compounds.

Thus extractives of industrial samples of hydrolytic lignins are multicomponent mixture. Chemical composition of extractives includes valuable group such us terpens, acid resins, sterins.

The pretreatment of aspen wood is carried out in system «ch₃cooh–H₂O₂–H₂O–H₂SO₄» for reception of products with the least disrupt components, and with the purpose of investigation of basic components behavior of vegetative raw material at chemical modification. The influence of the fluid module on properties of the firm residual at pretreatment of aspen wood is investigated.

The reaction of carboxymethylation of aspen wood pretreatment in system «ch₃cooh–H₂O₂–H₂O–H₂SO₄» is investigated. The optimal fluid module of pretreatment of aspen wood for reception of wood carboxymethyl products, having complex useful properties, (contents of carboxymethyl groups, solubility in water and uniformity on fractional composition) is – 5.
Sudakova I.G., Ivanchenko N.M., Kuznetsov B.N. Production of wood fuel briquettes with the use of birch bark suberin as a biding agent

The influence of suberin concentration, the pressing temperature and pressure of on the strength and water resistance of wood fuel briquettes has been studied. The optimal technological parameters of hot pressing process were selected in order to produce wood briquettes with high performance properties. It was established, that the heat treatment of initial fuel briquettes improve their physical-mechanical characteristics.

Influence various solvents (ethyl acetate, acetone, methanol) on an yield substances and a quantitative ratio of fractions of compounds is investigated in structure of a phenol complex of a bark of larch gmelinii (Larix gmelinii (Rupr.) Rupr.). It is shown, that use of various solvents allows to receive from a bark of a larch biologically active complexes of polyphenol compounds with quantitative prevalence of those or other fractions and, probably, having various physiological activity.

In the work the parameters of larch bark ethylacetate extraction process have been studied which are necessary for technological management of antioxidant complex and wax production. It has been shown that the use of raw material milling stage and extraction temperature from 60 to 70 ºС reduce the time of extraction Also it has been established that taking ginto account of raw material damp determines the composition of obtained extracts.

New variants of extractives exhaustion in binary and ternary water/organic solvent systems from conifers bark were studied. It was found that these ways provide high total yield extractives, rich in different substances composition and they are more practically feasible then traditional ones.

In work with the use HPLC-analisys probed flavonoids in ethylacetat extracts from poplar balsamic buds, growing in Krasnoyarsk. It is shown that their composition differs from the poplars of other regions. The dynamics of flavonoids is resulted in different periods of development of tree.

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. RESEARCH of QUALITATIVE STRUCTURE of ESSENCIAL OIL ORIGANUM VULGARE L., GROWING In EAST SIBERIA

The method GC-MS investigates a chemical compound of essential oil Origanum vulgare L. wild-growing and cultivated of east Siberia region (Russia). It is revealed 136 (in cultivated 155) components, from them it is identified 36 (in cultivated 39) connections. The basic making essential oils are caryophyllene oxide, spatulenol, (-)-4-terpineol. Essential oil of Origanum vulgare this region is characterized by the low contents of phenolic connections thymol and carvacrol (in the sum no more than 1,34%).

The method of total flavonoids content determination in the aerial part of Ortilia secunda (L.) House is created. Relative error of determination is no more than 3%. Total flavonoid’s content (converting in rutin) no less that 2%.

The conditions of fructose - resorcinol reaction realization are investigated and the optimum parameters are revealed. The technique of quantitative definition of fructose in a medical mean «Levilose» is developed. The relative mistake of definition does not exceed 3%.

There were determined the sizes of the particles of dispersed phase of the colloidal system chaga water extracts with use of electronic paramagnetic resonance (EPR). It was installed that colloidal system of the chaga water extracts may contain large and small particles, referred by us to micelles and sub micelles of polyphenoloxycarbon complex (PPC). Their sizes are close to the sizes of micelles and sub micelles of cow’s milk casein.
