Determination of some physical and chemical indicators and the quality of the content of vitamins, minerals in the berries of barberis (different-closed) growing on the territory of the Republic of Tajikistan

Purpose of the study. Further study of the physico-chemical parameters and the quality of the content of vitamins, minerals in the berries of barberry (various racemes) growing on the territory of the Republic of Tajikistan.

Material and research methods. The materials of the study are samples of the fruits of the barberry of various racemes growing in the territories of various regions of the Republic of Tajikistan. The study of the physicochemical properties of the content of vitamins, minerals, sugar and extractive soluble substances in the berries of local species of barberry, which grows in the territory of the Republic of Tajikistan, was continued. Refractometer IRF-454 B2m was used to establish the authenticity and quality of the content of sugars and extractive soluble substances. Determination of the stability of dry extracts under natural conditions was carried out in accordance with OFS 42 - 0075 - 07 “Shelf life of drugs” and the World Instruction I-42-2-82 [7]. The data obtained in the course of the study were processed by the method of variation statistics using Student’s t-test, with the calculation of the boundary values of the confidence interval of the average result and the determination of the arithmetic mean error, for different values of the number of results.

Results of the study and their discussion. It has been established that the barberry is one of the multi-species taxa among the wild fruit plants of the republic growing in the vicinity of Dashtidjum of the Sh. Until now, the boundaries of growths and its volume, and their family ties remain unclear. The results of the analysis of samples of fresh and dried fruits showed different percentages of water and moisture content, ash and organic impurities, vitamins (C, B1, B2, B3, B6, P, E, K) and carotene. An attempt was also made to study the stability of the composition of active ingredients in dried barberry fruits during storage, which showed a noticeable increase in moisture content, a slight decrease in the content of polysaccharides and practically no changes in the amount of organic acids and flavonoids, which gave the right to conduct technological studies on the extraction of barberry fruits of various racemes, using various extractants.

Conclusion. The analysis of the barberry of various racemes growing on the territory of the Republic of Tajikistan showed the quality that these regulated requirements for fresh barberry berries during reception and storage can be used to determine the authenticity of raw materials and can be used as a medicinal plant in a wide variety of cases with pronounced choleretic, hepatoprotective and antioxidant activity.
