The territory of the Republic of Armenia is rich in wild fruit-bearing tree and shrub species, among which Hippophae rhamnoides L. occupies an important place. A review of the literature shows that there are studies devoted to the content and preservation of biologically active substances in the fruits of this plant. The aim of this study is to investigate the content of sucrose and ascorbic acid in the syrup obtained from the fruits of Hippophae rhamnoides L. The object of the study was Hippophae rhamnoides L., belonging to the Elaeagnaceae family. The content of sucrose and ascorbic acid was studied in the juice obtained from fresh fruits of Hippophae rhamnoides L. using a special mechanism. In order to determine the effect of sunlight on the composition of juice, its preparation was carried out under two conditions: in the presence of light and in darkness. The comparative indicators of ascorbic acid content in samples stored in light and darkness were similar for both Lori and Gegharkunik samples. In both regions, the amount of ascorbic acid decreased by 1.31 times under dark conditions. Thus, the content of ascorbic acid decreased in darkness, suggesting that it underwent degradation under these conditions.
