Chemical composition of ripen fruits of Solanum kieseritzkii C. A. Mey., distributed in Azerbaijan

The article presents the results of the study of the chemical composition of ripe fruits of Solanum kieseritzkii C. A. Mey. growing in Azerbaijan. As a result of the research, the content of dry substances (18.4-21.3%), total sugars (3.8-4.5%), organic acids (0.91-1.19%), pectin substances (0.61-0.78%), fatty oil (2.8-3.6%), ascorbic acid (312.1 mg%), carotenoids (38.7-43.6 mg%), flavonoids (504.3-596.3 mg%), catechins (202-212 mg%) were determined. Using the paper chromatography method, the fruits of Solanum kieseritzkii were found to contain glucose, fructose, sucrose, citric, succinic and malic acids, α-, β-, γ-carotenes, zeaxanthin, xanthin, lycopene, ritin, quercetin, catechin and epicatechin. From the dry pulp after obtaining the juice, 23% of fatty oil was isolated, containing 217 mg/100 g of carotenoids and 185 mg/100 g of tocopherols. The results of the study allow us to recommend fatty oil from the waste of fruits of Solanum kieseritzkii for obtaining functional products.
