Symmetrical Antioxidant and Antibacterial Properties of Four Romanian Cruciferous Extracts

Four alcoholic extracts from Romanian Cruciferous species—cabbage, acclimatized broccoli, black radish and cauliflower—were obtained in a microwave field. The showed good symmetric antioxidant activity (0.97–1.13 mmol/L TE) phenolic content (1001–1632 mg GAE/L). For the HPLC method, limit of detection (LOD), quantitation (LOQ) recovery degree were established. small values LOD LOQ indicated great fit data. method achieved satisfactory quantitative recoveries range 96%–122%, except for lowest sinigrin concentration (8.774 µg/mL). presence metals studied falls within allowed limits. four slightly asymmetric antibacterial activities against some Gram-positive Gram-negative bacteria, including strains with known resistance to antibiotics. Moreover, greater inhibitory effects exhibited bacteria. Asymmetrically, no inhibition was observed on fungal strains. Therefore, present results may suggest that extract formulas cabbage (presenting activity) might be helpful antimicrobial fight could successfully used selected cases
