This thesis deals with lesser known antioxidants and promising vegetable species. In seven kinds of vegetables grown on the property Faculty of Horticulture in Lednice in 2014 was determined by the content of ascorbic acid and antioxidant capacity. The antioxidant capacity was determined by DPPH (diphenyl-s pikrylhydrazylovým radical). For the determination of ascorbic acid method was chosen liquid chromatography (HPLC). Selected vegetable species were: Swiss chard (Beta vulgaris ssp. Cicla L.), Chinese cabbage (Brassica chinensis L.), savoy cabbeg(Brassica oleracea var. Acephala DC), mizuna (Brassica rapa L. subsp.
