The Far Eastern region is rich in fruit and berry raw materials with a high content of bioactive substances. The aim of the work is to study the chemical composition of wild berries of the Amur region of the Far Eastern region. Material and methods. The objects of the research were the berries of Sargent viburnum (Viburnum sargentii Koechne), Chinese Schisandra [Schisandra chinensis (Turcz.) Baill], and Amursky grapes (Vitis amurensis Rupr) harvested from 2011 to 2016. The content of organic acids and tannins was determined by titration, anthocyanins - spectrophotometrically, polyphenolic substances and β-carotene - photoelectrocolo rimetrically, vitamins B1, B2 - fluorometrically, vitamins B6 and E - by HPLC, hydroxycinnamine acids - by direct spectrophotometry. Results and discussion. The maximum amount of polyphenolic substances and vitamin C was found in V. sargentii berries, the average value of which was 1.01±0.04% and 85.2±2.4 mg/100 g, respectively. A high content of potassium was found in V. amurensis (an average of 188.5±2.2 mg/100 g) and V. sargentii (176.6±1.2 mg/100 g). The highest content of vitamins B1, B2, B6 was found in the berries of V. amurensis, the average content of which was, respectively, 0.071±0.002 mg/100 g, 0.065±0.002 mg/100 g and 0.081±0.004 mg/100 g. It was also found that in V. sargentii berries the level of all minerals and trace elements was the highest: calcium content in 100 g of berries was 41.4±0.8 mg, magnesium - 17.3±0.4 mg, phosphorus - 227.7±4.6 mg, manganese - 0.69±0.08 mg, iron - 0.60±0.08 mg, zinc - 0.90±0.08 mg. When consumed 100 g of V. sargentii berries, practically fully satisfies the need of an adult in vitamin C, in phosphorus and manganese - by about a quarter; in potassium, iron, and zinc, by 4-8%. 100 g of Sch. chinensis contains about 50% of the recommended daily intake of vitamin C, and 100 g of V. amurensis - about 10% of vitamin C and β-carotene, 7% of potassium, about 4% of group B vitamins. The studied berries can serve as a source of hydroxycinnamic acids and pectins. Conclusion. Studies of the chemical composition of the berries V. sargentii, Sch. chinensis, V. amurensis harvested in 2011-2016 indicates a wide range of bioactive compounds, the proportion of each of which varies.
