Assessment of antioxidant properties of different types of herbs by EPR and UV-VIS spectroscopy
Original language description
There is an increasing interest in complex characterization of medical herbs and herb products and isolation of their main active components including antioxidants. The first step of effective isolation of antioxidants from herbs is the extraction, whichmust be fast, simple and inexpensive, but also sensitive to respective bioactive components, environmental friendly and easy to automate. The aim of this contribution was to perform the assessment of antioxidant properties of various types of herbs commonly available in this territory in different extraction media by using modern spectroscopic techniques. Selected herbs were extracted in four different solvents, i.e., distilled water, 50% ethanol, 50% acetone and dimethylsulfoxide and subsequently analysed by EPR and UV-VIS NIR spectroscopy involving several assays. Total content of polyphenols (TPC), total content of flavonoids (TFC) and color characteristic using the CIE L*a*b* system were determined using the UV-VIS-NIR spectroscopy
