Raspberry (Rubus idaeus L.) is a shrub up to 2m high, the fruits of which have long been used in folk medicine in the treatment of colds, influenza, as well as to restore the body after a long illness. From the fruits of raspberries harvested in Ukraine an alcohol extract was obtained. Studies of the amino acid composition of the raspberry alcohol extract were performed by HPLC on an Agilent Technologies chromatograph (model 1100). Substances were identified by the retention time of the standards. Therefore, 22 free and 21 bound amino acids were determined. The highest levels for free amino acids were found for cysteine and for glutamic acid among the bound amino acids. The immunomodulatory effect of the extract was studied in vitro at dilutions 1/200, 1/20 and 1/10 in the reaction of blast transformation of lymphocytes. Mononuclear cells (lymphocytes) were used as the test material for study activity of the raspberry extract. The lymphocytes were extracted from venous heparinized blood. The intensity of the proliferative reaction was determined. As a result, numerical data of the total number of cells and the percentage of blast forms in the samples were obtained. As a control, mitogenic stimulation of lymphocytes by phytohemagglutinin at a concentration of 2.5μg/ml was performed. Studies have shown that raspberry fruit extract has a dose-dependent immunomodulatory effect. The highest activity was shown by the extract in a dilution of 1/10, increasing the transformation activation of immunocompetent cells by 50.0% compared to the intact control and by 10.4% compared to the phytohemagglutinin.
