The aim of present study is to make a comparative analysis of biochemical composition of fruits of selected genotypes and their suitability for food products. The experiment was conducted between RIMSA-Troyan and FRDI - Plovdiv. Fruits of two perspective genotypes of sea buckthorn were included in the experiment in the collection plantation of the institute. Biochemical composition (dry matter refractometric (%), total sugars (%), sucrose (%), inverted sugar (%), organic acids (%) tannins (%), pectin (%), ascorbic acid (mg%)), antioxidant activity, total polyphenols of fresh fruits and were studied. Data analyses show that the measured dry matter has higher values for the Siberian shed - 13.25%. The total polyphenols defined in the Siberian berries are three times more than the total Caucasian berries. Antioxidant activity was comparatively with similar values for both genotype due to the content of total polyphenols in fruits. The data were statistically distinguishable due to genotypes difference (p <0.05).
