Аннотация


The goal is to calculate the efficiency criteria of the technological process of percolation of Turkestan valerian roots and rhizomes, to work out an optimal technology for obtaining a thick extract of Turkestan valerian.

Materials and methods. In the experiment used roots and rhizomes of Turkestan valerian, purified water and ethanol of 96% pharmacopoeial quality.

When determining the optimum extraction conditions 70% ethyl alcohol was used as the extractant. The extraction method is percolation. Each extract fraction was taken at a DER 1: 1 step, the amount of dry residue in each fraction was estimated and the main indices of the process dynamics were calculated.

Results. The total yield of extractives from 100 g of the raw materials was 10.79 g, which is more than 12.44%. The maximum number of stages of extraction for obtaining a thick extract is 7, a further increase in portions of the extractant does not lead to a significant increase in the yield of the finished product, which indicates the depletion of the raw material.

Тhe optimal technology for getting a thick extract consists of the following classical steps: grinding raw materials, preparing the extractant, preparing herbal raw materials, infusion, percolation, settling, filtration, evaporation, packaging and marking.

Conclusion. Based on the conducted research, a technology for obtaining a thick extract from the roots and rhizomes of Turkestan valerian has been tested and experimentally substantiated, a laboratory regulation and methods for its standardization have been developed.
