Growing attention has recently been focused on the improvement of human health via the consumption of food or food supplements rich in antioxidants, dietary intake of which plays important role in protection of the human organism against oxidative damage. Connection between the antioxidant activity of naturally occurring compounds present in diet and prevention of certain diseases, e. g. coronary heart diseases or cancer is well documented [1, 2]. Medical plants are potent natural source of antioxidants; the most abundant are phenolic compounds, comprising flavonoids, phenolic acids, tannins, chalcones, coumarins or stilbens. The presence of non-flavonoid antioxidants such as ascorbic acid, α-tocopherol, glutathione, carotenoids and some metals (e.g. Cu, Fe, Mn, Zn and Se) has also been proved [3]. In the current study, the impact of post-production conditions on antioxidant status, content of selected polyphenols, colour and concentration of selected metals was evaluated in the group of 10 most popular medical plants conventionally produced in the Czech Republic. UV-VIS-NIR, EPR, HPLC and ICP-OES were employed for these purposes. The entire dataset of obtained experimental characteristics was processed also by multivariate statistical methods, e.g. by factor analysis (Fig.1), which shows strong correlations among individual parameters, particularly for polyphenolic compounds (rutin, caffeic acid, myricetin) TPC, TFC and antioxidant activity express as TEAC. From these results follows, that parameters as RS, colour characteristic L*, a*, TEAC and content of Na - as non-correlating – could be effectively used for differentiation of plants extracts according chosen technological, production and post-production criteria.
