title: Total polyphenols and antioxidant activity in different species of apples grown in Georgia.
abstract: Many studies have shown that biologically active components in plant-based foods, particularly phytochemicals, have important potential to modulate many processes in the development of diseases, including cancer, cardiovascular disease, diabetes, pulmonary disorders, Alzheimer's disease, and other degenerative diseases. The aim of the our study was to provide an updated understanding and analysis of various apple sorts growing in Georgia by the compounds with a particular focus on their potential role(s) in disease risk and general human health. The Various sorts (Kekhura, Banany, Golden, Starty, Chempion, Aidaridy, Brotsky, Achabety, Sinapy, Jonagold and Antonovka,) of apples were investigated. The total phenolic content and antioxidant activity were studied in peel and flesh extracts and were measured by slightly modified method of Folin-Denis using Folin-Ciocalteu reagent and - 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method in those varieties of apples. Summarizing our data, we can conclude that, in accordance with the benefit to human health, the most prominent varieties of apples - Kekhura. It is rich with phenolic compounds, and also characterized by high scavenging activity. Also has good features Antonovka and Achabety. It should be noted that apple peel more helpful than the flesh, and therefore during consumption peeling of apples is unacceptable in terms of its usefulness.
