In recent decades the crisis of obtaining natural organic raw materials attracts the attention of researchers to the use of renewable plant resources, to their deep processing in order to obtain the maximum yield of useful products. One of the most promising types of organic raw materials is spruce wood. Special attention of researchers to spruce wood is determined by its large reserves in Russia, the characteristics of its physicochemical properties and the composition of components. In this regard, studies have been conducted in this work aimed at studying the possibility of maximum extraction of useful products (galacto-glucomannans) from spruce wood.
In the course of the experiments it was found that extraction of crushed spruce wood with saturated steam at a temperature of 170 °C for 40 minutes allowed dissolving about a quarter of the wood material and obtaining the maximum yield of high polymer hemicelluloses (mainly galacto-glucomannans) after 30 minutes. It is determined, that by successive precipitation of hemicellulose in ethanol, acetone and methyl tertiary butyl ether the maximum yield of galactose, glucose and mannose can be obtained. The resulting substances form the basis of biologically active natural products necessary to meet the needs of medicine, pharmacology, agriculture and the cosmetic industry.
