The radish (Raphanus sativus L.) is a vegetable of the Brassicaceae family cultivated worldwide and has several medicinal properties. Its biological activities are related to various secondary metabolites present in the species, especially phenolics. Thus, the objectives of this study were the chemical analysis and evaluation of the antioxidant and antimicrobial activities of the dry extract and fractions of the fodder turnip leaves (R. sativus var. oleiferus Metzg.). Samples were analyzed by mass spectrometry and the antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical method and the reducing power method. Antimicrobial activity was determined by the agar diffusion and microdilution methods. The total phenols were concentrated in the butanol fraction (121.27 mg GAE/g) and the flavonoids were concentrated in the ethyl acetate fraction (98.02 mg EQ/g). The ethyl acetate fraction showed the best antioxidants results, with 83.45% of free radical scavenging and 11.34% of ferric ions reduction. The analysis of antimicrobial activity showed that the dry extract had the highest average zone of inhibition against Bacillus subtilis (18.67 mm). Smaller values of the minimum inhibitory concentration for Micrococcus luteus were, and the ethyl acetate fraction showed a lower minimum inhibitory concentration (0.1 mg/ml) for that microorganism. There was a strong correlation between the antioxidant activity and the content of phenols and flavonoids. The results showed the potential antioxidant and antimicrobial activities of this extract with the ethyl acetate fraction being most promising for further studies.

Polyalthia Longifolia

Background: Polyalthia longifolia which originates from India is rich with various useful phytochemicals which are valuable for human health. Accordingly, the current study was conducted to evaluate the combinational antimicrobial activity of P. longifolia Ethyl Acetate Fraction (PLEAF) with ampicillin, antioxidant and cytotoxicity activities. Methods: The evaluation of the synergistic activity of PLEAF fraction and ampicillin against MRSA local isolate was conducted with various antimicrobial assays. Results: The Minimum Inhibitory Concentration (MIC) values of PLEAF fraction (62.5 μg/mL) and ampicillin (5000 μg/mL) were found to decrease to 15.63 μg/mL for PLEAF and 2500 μg/mL for ampicillin respectively in the Fractional Inhibitory Concentration (FIC) assay against the MRSA bacteria. The 2,2-diphenyl1-picrylhydrazyl (DPPH) and nitric oxide free radical scavenging activities showed that PLEAF fraction possessed high antioxidant activity and the combinational of PLEAF fraction and ampicillin exhibited moderate antioxidant activity. The total phenolic content (TPC) of PLEAF was 168.22 ± 0.00407 μg GAE/g of PLEAF fraction. Discussion: henolic compounds might be responsible for the observed antioxidant and antimicrobial activity of PLEAF fraction. In addition, in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity test against Vero cells the PLEAF fraction was proven to be non-toxic (98.14% of cell viability) and the combination of PLEAF fraction and ampicillin treatment against the Vero cells showed an improved cell viability (52.44%) as compared with ampicillin alone in the treated group. Conclusions: The PLEAF fraction works well in combination with ampicillin to kill the MRSA local resistance strain. PLEAF fraction also showed favourable antioxidant activity and improved Vero cell viability in the presence of ampicillin which is an important attribute of PLEAF fraction to be used in the future combinational therapy.
