The aim of this work was to determine, comparatively, the content of vitamin C (by iodometric method), polyphenols (by Folin Cioc?lteu assay), chlorophyll pigments, carotenes, xanthophylls (by spectrophotometric method) and the antioxidant activity (by CUPRAC method) for some frozen vegetables on the Romanian market: okra (Abelmoschus esculentus), green beans (Phaseolus vulgaris)- Serengeti variety and green peas (Pisum sativum) ? Alaska variety. Frozen peas was the most rich in ascorbic acid (9.32 mg/100g) and frozen green beans showed the low concentration of vitamin C (6.14 mg/100g). Also, peas was the richest in chlorophyll pigments (total chlorophylls: 23.72 mg/100g, from which 11.89 mg/100g chlorophyll ?a? and 8,20 mg/100g chlorophyll ?b?), while the lowest content of these pigments was found in green beans (total chlorophylls: 6.37 mg/100g, 3.86 mg/100g chlorophyll ?a? and 2.26mg/100g chlorophyll ?b?). Frozen okra had the highest concentration of carotenoids (carotenes and xanthophylls): 21.47 ?g/g, followed by frozen peas: 18.45 ?g/g. In the terms of polyphenols content, frozen peas had the highest concentration (78.34 mg gallic acid/100g), followed by okra (72.47 mg gallic acid/100g) and green beans. As in the case of total polyphenols, the highest antioxidant activity was found in frozen peas (4.36 mg Trolox/g), followed by frozen okra (3.75 mg Trolox/g).
