Description
| - Antioxidanční aktivita 17 českých léčivých rostlin byla studována a srovnána s antioxidační aktivitou zeleného čaje. Antioxidační aktivita vodných a ethanolových extraktů studovaných rostlin byla stanovena spektrofotometrickou metodou používající stabilní syntetický volný radikál DPPH (2,2-difenyl-1-pikrylhydrazyl). Ve vodných extraktech byl také stanoven celkový obsah látek s redukčními vlastnostmi, a to pomocí průtokového analyzátoru s amperometrickou detekcí (detekční potenciál +0,7 V). Významnou antioxidační aktivitu vykazovaly roslitny čeledi Rosaceae (šípky a listy jahodníku, maliníku a ostružníku), rostliny čeledi Lamiaceae a květy lípy a černého bezu. (cs)
- The antioxidant activity of 17 Czech medicinal plants was studied and compared with the antioxidant activity of green tea. The antioxidant activities of water and ethanol extracts of the plants tested were determined by a spectrophotometric method using the stable free radical DPPH (2,2-diphenyl-1-picrylhydrazyl), and further the contents of the compounds with reducing properties in water extracts were determined by flow injection analysis with amperometric detection (using a detection potential +0.7 V). Considerable antioxidant activities were found in the extracts of plants from the Rosaceae family (rosehips and leaves of raspberry, blackberry, and strawberry), the Lamiaceae family (oregano, sweet balm, thyme, dead-nettle, and mint), and flowers of linden and elder.
