Wild cyclamen tubers (Cyclamen purpurascens Mill.) (mountain Kukavica, Southeast Serbia) were used as material for extraction in this study. Aqueous extract was obtained by reflux extraction on boiling temperature with hydromodulus 1:20 m/v during 180 minutes. The total phenolic content was determined spectrophotometrically by the method of Folin-Ciocalteu, and the total flavonoids content by method with AlCl3. The antioxidant activity of extract was investigated spectrophotometrically by DPPH and ABTS test. Disc-diffusion method was used for antimicrobial activity investigation on the following pathogenic microorganisms: Staphylococcus aureus, Bacillus cereus, Enterococcus faecalis, Pseudomonas aeruginosa and Klebsiella pneumoniae. The content of total phenols was 8.27 mg GAE/g dry extract while the total flavonoid content was 11.51 mg RE/g dry extract. The extract concentrations required to neutralize 50% of the initial concentration of DPPH radicals (EC50) after 20 minutes incubation and immediately after adding DPPH radical solution were 0.413 and 2.0 mg/ml, respectively, while concentrations of extract required to neutralize 50% of the initial ABTS radicals concentration is 0.743 mg/ml. The extract showed the highest antimicrobial activity on bacteria Staphylococcus aureus. The presented results indicate that cyclamen tubers extract is a potential source of natural antioxidants and antimicrobial agents.

Ancient Times

Since ancient times plant as sources of medicinal compounds have continued to play a dominant role in the maintenance of human health. To treat chronic and infectious diseases plants used in traditional medicine contain a wide range of ingredients. In this regard, Cassia auriculata L. (Caesalpiniaceae) is widely used in Ayurvedic medicine as a tonic, astringent and as a remedy for diabetes, conjunctivitis, ulcers, leprosy, skin and liver diseases. The aim of present study was to evaluate the antimicrobial activity of ethanolic extract of Cassia auriculata leaves and flowers (CALE & CAFE). CALE and CAFE exhibited broad spectrum antimicrobial activity against standard strains of Staphylococcus aureus, Escherichia coli and Bacillus subtilis and exhibited no antifungal activity against standard strains of Candida albicans and Aspergillus niger. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) was carried out for CALE and CAFE. The results obtained in the present study indicate that the CALE and CAFE can be a potential source of natural antimicrobial agents.

The aim of this study was to evaluate the antimicrobial activity of aqueous extract ofPsidium guineenseSwartz (Araçá-do-campo) and five antimicrobials (ampicillin, amoxicillin/clavulanic acid, cefoxitin, ciprofloxacin, and meropenem) against twelve strains ofStaphylococcus aureuswith a resistant phenotype previously determined by the disk diffusion method. FourS. aureusstrains showed resistance to all antimicrobial agents tested and were selected for the study of the interaction between aqueous extract ofP. guineenseand antimicrobial agents, by the checkerboard method. The criteria used to evaluate the synergistic activity were defined by the fractional inhibitory concentration index (FICI). AllS. aureusstrains were susceptible toP. guineenseas determined by the microdilution method. The combination of theP. guineenseextract with the antimicrobial agents resulted in an eight-fold reduction in the MIC of these agents, which showed a FICI ranging from 0.125 to 0.5, suggesting a synergistic interaction against methicillin-resistantStaphylococcus aureus(MRSA) strains. The combination of the aqueous extract ofP. guineensewith cefoxitin showed the lowest FICI values. This study demonstrated that the aqueous extract ofP. guineensecombined with beta lactamics antimicrobials, fluoroquinolones, and carbapenems, acts synergistically by inhibiting MRSA strains.

Aims: The aim of this study is to evaluate the antimicrobial activity of the R. brasiliensis aerial part extracts collected in southern-Benin. Methodology: The phytochemical screening was performed by a differential precipitation staining method. Aqueous and ethanolic extracts were made using conventional method with water and ethanol as solvent. The obtained extracts were used to evaluate their antimicrobial activity on Staphylococcus aureus strains isolated from skin infections and ten reference strains by the solid-medium diffusion method. The minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) were determined by the liquid macro-dilution method. The cytotoxic effect of the extracts was evaluated on Artemia salina larvae obtained by hatching. Results: The phytochemical screening showed a strong presence of tannins, flavonoids, terpenes, steroids and a medium presence of alkaloids, anthocyanins and mucilage’s. The extraction yields vary according to the solvent: water (15.5%) and ethanol (10.30%). The two extracts variously (p<0.001) inhibited the growth of Staphylococcus aureus strains isolated from skin infections and four reference strains (Staphylococcus aureus ATCC29213, Pseudomonas aeruginosa ATCC27853, Proteus mirabilis A24974, Escherichia coli ATCC25922). However, there is no difference (p > 0.05) in inhibition of strains growth between 24h and 48h. The largest diameter (21±0.75 mm) of inhibition with the reference strains was obtained with P. aeruginosa by action of the aqueous extract. Regarding Staphylococcus aureus strains isolated from skin infections, the largest diameter of inhibition is about 19.25±2.75 mm obtained with strains isolated from ulcers. The average mics of 2.81 mg/ml and 2.08 mg/ml were obtained respectively for the aqueous and ethanolic extracts in the presence of the reference strains. The LC50 determination obtained using the regression line is 0.36 mg/ml for the aqueous extract and 1.16 mg/ml for the ethanolic extract. Conclusion: The aqueous extract is more effective because of its action spectrum. This extract can be used for the development of a soap or ointment to fight against skin infections.

Resistance against synthetic antimicrobial agents is one of the major global public health challenges that compel scientists to search for alternatives including those of plants origin. Staphylococcus aureus and Escherichia coli are bacteria responsible for a variety of infections and diseases that causes significant morbidity and mortality in humans and animals. E. coli is widely distributed in nature and commonly found in lower gastro intestinal tracts of most warm-blooded animals associated with urinary tract infections and enterocolitis in humans and colibacillosis in poultry. This study was carried out to investigate antimicrobial activity of methanolic leaf extracts of Bidens pilosa against S. aureus and E. coli. Agar well diffusion method was used to assess antimicrobial activity of the leaf extracts at 20%, 50% and 70% concentrations respectively based on measured zone of inhibition. The leaf extracts of Bidens pilosa produced significant zone of inhibition indicating its antimicrobial activity against E. coli and S. aureus. The antimicrobial activity was demonstrated in all concentrations however, the highest zone of inhibition (18.5mm and 32mm) for E. coli and S. aureus respectively was at 70% concentration. The results shows that Bidens pilosa leaf extracts have antimicrobial activity against the tested bacteria and have the potential for further development including identification of active components that can be tested for treatment of E. coli and S. aureus associated conditions.

The present study was conducted to investigate in vitro antimicrobial activity of ethanolic extracts obtained from leaves and pseudobulbsof Coelogyneflaccida against Staphylococcus aureus subsp. aureus Rosenbach (ATCC®25923™) (mecA negative), Staphylococcus aureus subsp. aureus Rosenbach (ATCC®29213™)(mecA negative, Oxacillin sensitive, weak β-lactamase-producing strain), Staphylococcus aureus NCTC 12493 (mecA positive, Methicillin-resistant, EUCAST QC strain for cefoxitin).The antimicrobial susceptibility testing was done on Muller-Hinton agar by the disc diffusion method (Kirby-Bauer disk diffusion susceptibility test protocol). The leaves and pseudobulbs of C. flaccida plants, cultivated under glasshouse conditions, were sampled at M.M. Gryshko National Botanic Garden (NBG), National Academy of Science of Ukraine. Freshly leaves and pseudobulbs were washed, weighed, crushed, and homogenized in 96% ethanol (in proportion 1:19) at room temperature. The extracts were then filtered and investigated for their antimicrobial activity. The cultivation medium was trypticase soy agar (Oxoid™, UK), supplemented with 10% defibrinated sheep blood. Cultures were grown aerobically for 24 h at 37°C. The cultures were later diluted with a sterile solution of 0.9% normal saline to approximate the density of 0.5 McFarland standard. The McFarland standard was prepared by inoculating colonies of the bacterial test strain in sterile saline and adjusting the cell density to the specified concentration. The examined ethanolic extracts obtained from leaves and pseudobulbs of C. flaccida showed remarkable antibacterial activities against different S. aureusstrains. The observed activity may contribute to the reasons why orchids are used for infectious and inflammatory conditions in ethnomedicine. The research showed that ethanolic extracts of C. flaccida possess the highest antibacterial potency against S. aureus NCTC 12493 strain. These findings led the authors to suggest that these extracts may be used as natural antiseptics and antimicrobial agents in medicine and veterinary practice. Nevertheless, despite the promising results, more research should be carried out to further evaluate the roles of particular compounds, isolated from all parts of orchid plants, attributable to antimicrobial activity.

AbstractThe increasing resistance against classical antibiotic treatment forces the researchers to develop novel non-toxic antimicrobial agents. The aim of this study was to determine the antimicrobial properties of seven different porphyrins having distinctive hydrophobicity/hydrophilicity: P1 meso-tetra(4-methoxy-phenyl)porphyrin, P2 Zn(II)-meso-5,10,15,20-tetrapyridylporphyrin, P3 meso-tetra(p-tolyl)porphyrin, P4 5,10,15,20-tetraphenylporphyrin; P5 (5,10,15,20-tetraphenylporphinato) dichlorophosphorus(V) chloride, P6 5,10,15,20-tetrakis-(N-methyl-4-pyridyl) porphyrin-Zn(II) tetrachloride, P7 Zn(II)-5,10,15,20-meso-tetrakis-(4-aminophenyl)porphyrin. The meso-porphyrin derivatives were screened for their antimicrobial activity against six reference strains: Streptococcus pyogenes ATCC 19615, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 700603, Pseudomonas aeruginosa ATCC27853 and Candida albicans ATCC 10231. The antimicrobial activity of these samples was evaluated by the agar disk diffusion method and dilution method, with the determination of the minimum inhibitory concentration (MIC), the minimum bactericidal concentration (MBC) and the minimum fungicidal concentration (MFC). The most significant result is provided by the water-soluble P5 manifesting an obvious antimicrobial activity against Streptococcus pyogenes. On the other hand, P6 is a moderately active derivative against Streptococcus pyogenes and Escherichia coli and P7 presents moderate activity against Streptococcus pyogenes and Staphylococcus aureus. All the tested porphyrin bases, presenting hydrophobic character, have no antimicrobial activity under the investigated conditions. The common characteristics of the porphyrins that act as promising antimicrobial agents in the non-irradiated methods are: the cationic nature, the increased hydrophilicity and the presence of both amino functional groups grafted on the porphyrin ring and the coordination with Zn or phosphorus in the inner core.

The medicinal value of the plants is due to their chemical components that bring a definite physiological action on the human body to prevent the diseases. In this work, we investigated the antimicrobial activity of leaves’ extracts of Quercus robur L., collected from the Algerian upper highlands, on ten bacterial strains and one fungal strain known to be pathogenic. First, we performed a qualitative phytochemical analysis, and second, antimicrobial activity tests performed by agar diffusion method (disc and well) with the determination of MIC by broth macro-dilution method. Given the results, it appears that obtained macerates of Quercus robur L. were rich in bioactive phytoconstituents such as alkaloids, anthraquinones, saponins, tannins, and other components. The yield of aqueous and methanolic macerates of leaves was 8.5 ± 1.41 and 22.4 ± 4.36%, respectively. The bacterial resistance was relatively important to several antibiotics, namely, ampicillin, amoxicillin + clavulanic acid for strains of Escherichia coli and Salmonella sp. However, Staphylococcus aureus strains were resistant to fusidic acid, penicillin, and oxacillin; while Enterococcus faecalis was resistant to fusidic acid, penicillin, oxacillin, and ticarcillin. The antibacterial activity of the macerates toward tested microbial strains showed that the aqueous and methanolic macerates of the leaves were proportional to the tested concentration and active not only against Gram-positive and Gram-negative bacteria but also on the fungal species Candida albicans. The estimated MIC for Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus was in the order of 10 mg/mL, which seems more effective than toward Salmonella sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, and Candida albicans which were in the order of 30 mg/mL. These preliminary results confirm that the part of the studied plant had a very good antimicrobial activity that was proportional to the serial concentrations of the tested extracts.
