The purpose of research is to study the biochemical composition of apricot fruits (Prunus armeniaca L., Rosaceae). The material for the study was the apricot varieties Aisberg, Vodoley, Gwiani, Lel, Tsarsky and Zachatievsky (selected form) bred by the Tsitsin Main Botanical Garden of the Russian Academy of Sciences (Moscow). The cultivars were grafted onto P. armeniaca seedlings planted in 2002 at the age of 6 on the territory of the Zachatievsky convent (Moscow, Ostozhenka st.). Apricot fruits were harvested in mid-August 2021 and 2022 in the stage of technical maturity, when the fruit has reached its maximum size, the flesh is greenish-yellow, dense. The sample for measurements, cm, and weighing, mg, was 25 fruits of each variety. Biochemical analysis was carried out in 2021-2023 in the VILAR laboratory according to generally accepted methods of the State Pharmacopoeia of the Russian Federation, XIV edition. Drying of freshly picked peeled fruits was carried out in a ShS-40 laboratory oven with forced convection at a temperature of 60 °C. The content of bioflavonoids in apricot fruits was determined, it is 70.1-130.1 mg%; carotenoids - 16.6-42.5 mg%. The fruits contain 105.6-161.0 mg% of ascorbic acid, from 12.7 to 18.4 % of organic acids. In the laboratory of the Tsitsin Main Botanical Garden of the Russian Academy of Sciences, it was found that apricot fruits accumulate up to 26.8% of sugars, in terms of air-dry weight. It was noted that monosaccharides account for the main share in the composition of sugars. Apricot fruits are saturated with useful substances, and varieties and selected forms are suitable for further breeding to expand the stable assortment in the central zone of the Russian Federation. Aisberg and Gwiani varieties, saturated with monosaccharides, vitamin C and carotenoids, have the most pronounced dietary properties.
