Original Abstract

Currently, there is an increasing interest in complex characterization of medical plants and isolation of their main bioactive components including antioxidants. Herbs are rich sources of natural antioxidants, which are mainly responsible for their health benefits e.g. anticarcinogenic, antimutagenic or antiinflamatory. The antioxidant effect of herbs is mainly attributed to phenolic compounds such as flavonoids and phenolic acids. These compounds can help preventing oxidative damages caused by free radicals, retard the progress of chronic diseases or lipid oxidative rancidity in foods. Therefore herbs have been used for centuries to flavour and conserve food, to treat health disorders and to prevent diseases. The first step of effective isolation of antioxidants from herbs is the extraction, which must be fast, simple and inexpensive, but also sensitive to respective bioactive components, environmental friendly and easy to automate. To do so, the optimalization of extraction process is necessary. The aim of this study was to perform the assessment of antioxidant properties of various types of herbs commonly available in Czech Republic in different extraction solvents by using modern spectroscopic techniques - UV-VIS NIR and EPR spectroscopy.
