The article includes the results of the phytochemical evaluation in frozen and dried fruits of three taxa of Elaeagnus umbellata Thunb. ('Amoroso', 'Fortunella' and 'Sweet ˈnˈ Sour'). The analysis of ascorbic acid revealed values between 85.97 and 99.69 mg/ 00 g in frozen fruits and 27.62 - 35.34 mg/ 00 g in dried fruits. Irrespective of the type of fruit preservation, the maximum amount of vitamin C was detected in the cultivar 'Amoroso'. The minimum amount of tannins was found to be characteristic of the cultivar 'Sweet ˈnˈ Sour' in both frozen ( .25%) and dried ( .88%) fruits. The total phenolic content recorded values from 037.6 mg GAE/ 00 g d.m. to 83.64 mg GAE/ 00 g d.m. in frozen fruits and from 2 . 4 mg GAE/ 00 g d.m. to 260.34 mg GAE/ 00 g d.m. in dried fruits. The comparative analysis of the obtained data allowed us to conclude that the fruits of analysed taxa are a promising source of natural antioxidants, which provide them with powerful antioxidant properties, and drying proved to be a more effective method of preserving the fruits than freezing, maintaining a higher amount of active principles.
