| description | The problem of type 2 diabetes due to its prevalence, severity, and complications is one of the most pressing in the world. Plants of the genus Vaccinium are promising sources for the creation of hypoglycemic and hypolipidemic medicines. Studies have shown that the extract from cranberry leaves, obtained with 50 % ethanol solution has prospects to be used for correcting insulin resistance. Therefore, for creating new medicines based on cranberry leaves, it is necessary to determine the optimal parameters of biologically active substances (BAS) extraction from this raw material.
The aim of the research is to determine the parameters of BAS extraction from cranberry leaves (Oxycoccus macrocarpus (Ait.) Pursh) for creating a new dry extract with hypoglycemic activity.
Materials and methods. The object of the study was cranberry leaves. Extracts from the leaves were obtained with 50 % ethanol solution in a ratio of 1:10; 1:15; 1:20; 1:25; 1:30 and 1:35 by maceration at room temperature for 8 hours. The extraction was repeated four times with new portions of the extractant, collecting each extract separately. Identification of phenolic compounds was performed by thin-layer chromatography. An assay of phenolic compounds was carried out by spectrophotometric methods. The mass transfer coefficient of each stage (miBAS/Viextragent) was calculated for each indicator and the dependence of these factors on the extraction multiplicity to determine the rational extraction was derived using the software Statistics.
Results. Gallic and chlorogenic acids, rutin, quercetin, and hyperoside were detected on TLC of cranberry leaves extracts in comparison with standard samples of substances. The content of the sum of hydroxycinnamic acid derivatives in terms of chlorogenic acid, the number of flavonoids in terms of rutin, and the content of the sum of phenolic compounds in terms of gallic acid were determined. It was established that the exhaustive extraction of BAS with 50 % ethanol solution from the cranberry leaves provides a ratio of 1 to 100–110. It was rational to carry out BAS extraction from cranberry leaves in a ratio of 1:10 twice, this would ensure the maximum yield of BAS at the minimum cost of the extractant.
Conclusions. It was found that was rational to extract BAS with 50 % ethanol solution from cranberry leaves in a ratio of 1:10 twice using mathematical and statistical methods. It would be used in the future in the development of extract technology. |
