Original Abstract
The impact of extraction solvents on concentration of selected polyphenols, antioxidant activity and colour parameters was evaluated for group of 10 the most popular medical plants conventionally produced in the Czech Republic. High Performance Liquid Chromatography, Electron Paramagnetic Resonance and Ultra Violet Visible Near Infrared Spectroscopy were employed. The entire experimental characteristics were processed by multivariate statistical methods in order to assess the influence of extraction conditions on monitored characteristics and for mutual differentiation of medical plant samples according to the extraction solvent used. Results obtained clearly proved the successful differentiation of medical plant samples by means of canonical discrimination analysis, reaching 96.7% correctness, as well as by k-th nearest neighbour method reaching 100% for k = 1 and 60% for k = 2. The results unambiguously confirmed also the importance of selection of the most proper extraction conditions to obtain the highest possible yields of target compounds/molecules with health-promoting and antioxidant properties.
