Research of Antioxidant Activity of Aronia melanocarpa Fruits and Viburnum opulus Fruits

Abstract

The general interest and the possibility of extensive use of polyphenol compounds determines the relevance of search of new low-cost and available sources of raw rnaQ-ial. In this aspect the Aronia melanocarpa. Viburnum op ulus are promising. I decided to determine the optimal concentration of ethyl alcohol, providing the highest antioxidant activity were prepared tinctures A. melanocarpa fruits, Viburnum opulus fruits and their combination. For this I took tinctures were made 1: 5 with percolation. Alcohol (40%, 70%, 95%) was used as an extracting agent; medicinal plant material - V. opulus fruits, A. melanocarpa fruits. Study of AOA was carried using test systems and method of EPR spectroscopy. Statistical analysis of the obtained data was done with Statgraphics (n = 6). Conclusion: The highest antioxidant activity was shown tincture V. opulus fruits 40%. In that way the optimal concentration of ethyl alcohol, providing the highest antioxidant activity is 40%.
