STUDY OF THE PROCESS OF EXTRACTION OF ISOSALIPURPOSIDE FROM THE FLOWERS OF HELICHRYSUM MARACANDICUM (HELICHRYSUM MARACANDICUM POPOV EX KIRP.)

The purpose of this research is to study the process of extraction of isosalipurposide, and on the basis of the data obtained, the development of an optimal technology for obtaining a dry extract from the flowers of Helichrysum maracandicum (Helichrysum maracandicum Popov ex Kirp.). In the studies, the circulation extraction method, which is widely used in local pharmaceutical enterprises, was used. Based on the characteristics of the technology for obtaining a dry extract, a four-factor experimental plan based on a 5x5 Greek-Latin square was used to study the extraction process of the target BAS. Four quantitative factors were chosen as variables: the degree of grinding of the raw material (factor A), the concentration of ethyl alcohol (factor B), the hydromodulus (factor C) and the soaking time of the raw material (factor D). The output parameter was the percentage of the sum of flavonoids in terms of isosalipurposide in the resulting product. The results of dispersion analysis showed that the most complete yield of isosalipurposide was observed with the following indicators of variable factors: raw material grinding – 5–7 mm, extractant – 50% ethyl alcohol, hydromodulus 1 : 5, raw material soaking time – 9 hours. The expediency of using a short-term (10 min) ultrasonic treatment, which allows to increase the yield of the target BAS by 1.12 times, has been proved. The developed technology for obtaining a dry extract has been tested in industrial conditions. The resulting extract of Helichrysum maracandicum flowers in terms of quality met the requirements of pharmacopoeial articles: "Extracts" (SP XIV, GPM.1.4.1.21), "Extracts" (European Pharmacopoeia, 9th edition). Dry extract of Helichrysum maracandicum is recommended for use as a substance for the production of medicines and dietary supplements.
