Abstract
Bioactive components, antioxidant and antimicrobial activity of extracts from flowers, leaves and whole plant of Mentha аrvensis L. organically planted from the territory of Macedonia will be first object of this study. For this purposes, the extracts from dried and powdered plant materials will be extracted with different solvents and isolated using Clevenger-type apparatus. Furthermore, bioactive compounds, antioxidant and antimicrobial activity of Mentha plant will be evaluated. For determination of antioxidant activity of extracts from Mentha, ABTS or DPPH radicals will be used. For determination of antimicrobial activity, different gram positive and gram negative bacteria’s (such Escherichia Coli) as well as fungi (such Candida albicans) will be used.
Description (pomological) of some autohtones and international varieties pomegranate (Punica granatum L.) grown only in the region Valandovo in Macedonia. Furthermore, wе produsing juice from pomogranate varieties. In fresh, frozen and pasteurized juice analyzing bioactive components (sugars, organic acids, vitamin C, total phenols, tannins), determination antioxidant activity and extraction of oil. For determination of antimicrobial activity, different gram positive and gram negative bacteria’s (such Escherichia coli) as well as fungi (such Candida albicans) will be used.
Сensory evaluation of quality od pomegranate juice by using descriptive analysis.
These studies will include table grapes (Vitis vinifera L.), primarily for consumption in fresh condition. Among them analyzing bioactive components and their contents during the ripening of the grapes. Analysis of total anthocyanins, polyphenols, high and low molecular procijanidini - tannins with a spectrophotometer UV-Vis detector.
