Antioxidant And Antimicrobial Activities

Research background. Antioxidants are described as important compounds that are present at low concentrations to inhibit oxidation processes. Due to the side effects of synthetic antioxidants, research interest has increased considerably towards finding natural sources of antioxidants that can replace synthetic antioxidants. The emergence and spread of antibiotic resistance require the development of new drugs or some potential sources of novel medicine. This work aims to extract the secondary metabolites of S. cerevisiae using ethyl acetate as a solvent and to determine the antioxidant and antimicrobial activities of these extracted metabolites. Experimental approach. The antioxidant activities of the secondary metabolites of S. cerevisiae were determined using DPPH, ABTS, and FRAP assays. Furthermore, the antimicrobial potential of the ethyl acetate extract of S. cerevisiae in treating Cutibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis was assessed. Results and conclusion. Five out of 13 of the extracted secondary metabolites were identified as antioxidants. The antioxidant activity of the S. cerevisiae extract exhibited relatively high IC50 of 455.2689 μg/mL and 294.51 μg/mL for DPPH and ABTS respectively while the FRAP value was obtained as 44.4004 μg AAE/mL. Moreover, the extracts presented a significant antibacterial activity (p<0.05) against Staphylococcus aureus and Staphylococcus epidermidis at the concentrations of 100 mg/mL and 200 mg/mL, respectively. However, no inhibitory effect was observed against Cutibacterium acnes as the extract was only effective against Cutibacterium acnes at the concentrations of 300 mg/mL and 400 mg/mL (inhibition zones ranging from 9.0±0 to 9.333±0.577) respectively (p<0.05). Staphylococcus aureus was highly sensitive to the extract, with a MIC value of 18.75 mg/mL. Novelty and scientific contribution. This report confirmed the efficacy of the secondary metabolites of S. cerevisiae as a natural source of antioxidants and antimicrobials and suggest the possibility of employing them in drugs for the treatment of infectious diseases caused by the tested microorganisms.

 Objectives: Hydrocotyle sibthorpiodes is known to contain several phytoconstituents which are constantly involved in the formation of Silver nanoparticles that may affect several multi-drug resistant microbes. Therefore, the study was undertaken to evaluate the efficacy of different concentration of nano silver solution on three bacterial isolates. It was also aimed to qualitatively assess the different phytoconstituents responsible for the synthesis. Methods: Three bacterial isolates of Klebsiella pneumonia, Pseudomonas aeroginosa and Staphylococcus aureus were identified. Synthesis of AgNPs with different concentration (2/4/6/8/10μl/ml) was done and applied to the selected isolates. The phytochemical compounds of the ethyl acetate extract were assayed by several colored reactions qualitatively. Results: The size and stability biosynthesis of the metallic silver nanoparticles were confirmed by photophysical characterization as well as SEM (Scanning Electron Microscopy), XRD (XRay Diffraction), Zeta potential and DLS (Dynamic Light Scattering) with an average size of 13.37 ±10 nm. The increasing concentration of the particle solution showed significant inhibition zone for all the three isolates viz., Klebsiella pneumonia, Pseudomonas aeroginosa and Staphylococcus. aureus showing the value of 3.0±0.17, 2.7±0.32 and 3.6±0.57 respectively for 10 μl/ml concentration. Phytochemical screening of the whole plant extract also revealed an array of bioactive compounds which may have an effective role in the reduction process. Conclusion: The study demonstrated a simple, efficient and eco-friendly synthesis of stable silver nanoparticles from the ethyl acetate extract of Hydrocotyle sibthorpiodes having fairly superior antimicrobial activity against human pathogens.

The word endophyte means “in the plant” and refers to all microorganisms that live in the intercellular spaces of stems, petioles, roots and leaves of plants causing no apparent symptoms of disease. Seven endophytic fungi were isolated from the medicinal plant of Ocimum basilicum L. The fungal strain, labeled as 2L, was cultivated at large scale on the potato dextrose agar semi solid medium and was extracted with ethyl acetate. Normal phase silica gel column chromatography of the ethyl acetate extract afforded ergosterol (1), secalonic acid A (2) and secalonic acid D (3). The structures of these compounds (1-3) were elucidated unequivocally by UV, IR, MS, a series of 1D & 2D NMR analyses. The cytotoxicity of these compounds was evaluated by the MTT assay against human pancreatic cancer cell line. Secalonic acid A and secalonic acid D exhibited significant anti-pancreatic cancer activity with IC50 values of 7.3 and 1.6 ?M, respectively. Dhaka Univ. J. Pharm.
