CONTEMPORARY STUDIES OF ECOLOGICAL INDICATORS AND BIOLOGICALLY ACTIVE SUBSTANCES IN OLEA EUROPAEA L. LEAVES

Abstract

The purpose of the work was to apply some of the final results of three years of scientific research to economics, to summarize them in a comparative manner and in the final results for each year. The leaves contain a large group of phenolic compounds, most represented by flavonoids from the class of anthocyanidins group average 153.6 mg/100g dry weight, flavanones 197.2 mg/100g and flavanols 298.9 mg/100 g. The pelargonidin group is the most represented 184.0 mg/100 g dry weight. High anthocyanin content correlates with a reduced amount of photosynthetic pigments r =0.7-0.8. Flavonoids сhanges from 2.5 to 3.4% (average 248.5 mg/100 g dry weight). The remaining classes of flavonoids are distributed evenly in the leaves of Olea europaea L., averaging 35.60 mg/100 g. Only the share of flavonoids of the catechin group accounts for only 1.97 mg/100 g of dry weight
