DEVELOPMENT AND VALIDATION OF THE EXPRESS TECHNIQUE OF ALLOCATION AND QUANTITATIVE DEFINITION OF WATER-SOLUBLE POLYSACCHARIDES OF LEAVES OF ARCTIUM LAPPA L.

Abstract

Research objective was development of an express technique of allocation and quantitative definition of water-soluble polysaccharides in leaves of a Arctium lappa L. For acceleration of process of extraction of biologically active agents of leaves of a Arctium lappa and also augmentations of an exit of water-soluble polysaccharides, it was decided to use an ultrasonic bathtub. Varying process indicators, it was succeeded to pick up extraction conditions under which process of extraction and quantitative definition of water-soluble polysaccharides of leaves of a Arctium lappa comes down to 1.5 h, namely: an izmelchennost of raw materials of 0.5–1.0 mm, temperature – 80 °С, frequency rate of extraction – 3, duration of extractions – 15 min, ultrasound frequency – 35 kHz, a ratio of raw materials and the ekstragent of 1 g for 15 ml. The developed technique of a validirovan on indicators of repeatability, correctness, fastness and linearity therefore it is proved that it is a pretsizionna in the conditions of repeatability, is correct, steady and has rather rigid linear dependence of mass of a deposit on mass of the analyzed raw materials at gravimetric definition of water-soluble polysaccharides in leaves of а Arctium lappa. The technique can be used for the express analysis of quality of leaves of а Arctium lappa and also at industrial receiving an inulin from this type of raw materials.
