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.

Microorganisms, usually from the dental caries, are the main sources of diseases in dental pulp (root canals) and periapical region. Facultative bacteria and fungi have been identified in therapy resistant persistent endodontic infection. The objectives of this study was to evaluate the antimicrobial efficacy of Mineral Tri Oxide Aggregate (MTA) against therapy resistant endodontic microorganisms. The efficacy of MTA was also compared with that of calcium hydroxide. Six standard bacterial stains were used: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, bacillus subtilis, Candida albicans and Enterococcus faecalis. The agar diffusion method on Muller- Hilton media was employed. The plates containing media were inoculated with the specified bacterial suspensions. Two standard holes were prepared on each microorganism inoculated plate with a copper puncher and one hole was completely filled with MTA & the other with Ca (OH)2 . The plates were then kept at environmental temperature for one hour to ensure prediffusion and then incubated at 370C for 24 hours. After 24 hours, the diameters of inhibition zones were measured. Tests were replicated for thirty times for each sample and mean values were taken. Zone of inhibition as measured for MTA and Ca (OH)2 were statistically analyzed with Student’s t-Test and Post Hoc Games Howell Test and were presented as mean ± SD to compare of efficacy of MTA and calcium hydroxide on different microorganisms. Both MTA and Ca(OH)2 were found to produce zone of inhibition against Staphylococcus aureus (ATCC 25923), Pseudomonas aeruginosa (ATCC 27853), , Bacillus subtilis (BTCC 17 ), and Candida albicans (BTCC 493). MTA showed highest activity against S. aureus and lowest activity against P. aeruginosa which was similar to the activity range of Ca (OH)2 against the mentioned organisms. But both of them failed to produce any activity against E. coli and. E. faecalis. MTA was found to produce a lower efficacy than Ca (OH)2 while comparing the zone of inhibition between them and statistically it was significant. Mineral Tri Oxide Aggregate (MTA) showed antimicrobial efficacy against some therapy resistant microorganisms but it did not show antimicrobial efficacy against Escherichia coli and Enterococcus faecalis. MTA was found to produce a lower antimicrobial efficacy than Ca (OH)2.J Bangladesh Coll Phys Surg 2015; 33(3): 140-145

Medicinal plants have served as sources of medicine to treat and suppress the diseases, because many pathogens are gaining resistance to the current synthetic drugs. In addition, high cost and adverse side effects are commonly associated with popular Synthetic drugs. Therefore, there is need for continuous search for new drugs in order to overcome this emerging resistance. Plants synthesize bioactive compounds which are of great potential in agriculture, antimicrobial and anti-insect activity. The concentration of bioactive compounds in each plant species depends on the environmental conditions, age of the plant, relative humidity of harvested materials and method of extraction. Little is known on the phytochemical and antimicrobial potential of Alba and Rosea cultivars of Catharanthus roseus ethanol extracts. The leaves of Alba and Rosea cultivars were investigated for their phytochemical and antimicrobial properties. The study was conducted at Maseno University, Kenya. Plant Leaves were collected around Maseno University. Leaves of Alba and Rosea cultivars of Catharanthus roseus were air-dried in the shade, thereafter crushed into powder and ethanol extraction done using the Rotary evaporator. Antimicrobial activity of the pathogenic microorganisms was Candida albicans and Escherichia coli.  Disc diffusion method was used for antimicrobial tests. concentrations of ethanol leaf extracts consisted of 2.5, 5and 7.5 mg/mL with three replications.  Data on growth inhibition were subjected to analysis of variance (ANOVA) . Phytochemical analysis revealed the presence of tannins, flavonoids, terpenoids, saponins, alkaloids and phenols except steroids and glycosides. The ethanol leaf extracts were active against Candida albicans and and Escherichia coli. Alba leaves extracts showed higher inhibitory zones compared to Rosea leaves. The observed differences in antimicrobial activity could be due to differences in cell wall synthesis, structure and composition. The results of present study further confirm the use of these plants traditionally for the treatment of different ailments.

Microbiological Analysis

Antimicrobial activity of alcoholic extractions from the aboveground organs like bark and buds of Quercus robur L. was studied. The determination of the minimum inhibitory concentration (MIC) was performed with the use of double serial dilution in broth. The following microorganisms were used as test cultures: Bacillus cereus, Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus. It has been revealed that alcoholic extractions of the bark of Quercus robur have the widest spectrum of antibacterial activity in relation to Pseudomonas aeruginosa, Escherichia coli and Candida albicans. Results of microbiological analysis show that alcoholic extractions from the bark and buds have an antimicrobial effect on all of these strains with a single dilution (except for antimicrobial activity against Staphylococcus aureus with 70% extractions of bark of Quercus robur). In particular, relatively high antimicrobial activity was observed in alcoholic extracts of all buds concentrations against Candida albicans at a dilution of 2, 4 and 8 times and Escherichia coli at a dilution of 4, 8 and 16 times. The greatest antimicrobial effect against Pseudomonas aeruginosa has extracts from the bark and buds in all the studied concentrations of alcohol. A significant antimicrobial effect against Escherichia coli has 40% of extractions from the buds of Quercus robur when diluted by 2, 4, 8, 16, 32 and 64 times. The results can be used as justification for the introduction of a new type of raw material that is buds of Quercus robur, as well as drugs based on it in the State Pharmacopoeia of the Russian Federation as antibacterial phytopharmaceuticals.

Carbon Dioxide Extraction

The genus Lepidium L. from Brassicaceae Burnett. family covers over 150 species with an almost cosmopolitan spread. In Kazakhstan, 21 species are described, of which four species are characterized by medicinal properties (L. crassifolium Waldst. et Kit., L. perfoliatum L., L. ruderale L., and L. latifolium L.), used in folk medicine as means of antibacterial, irritant, laxative, antitumor, analgesic, and anthelmintic action. Methods. Raw materials were collected from Almaty region (Republic of Kazakhstan). Lepidium latifolium L. herb’s carbon dioxide extract (CO2 extract) was obtained by subcritical carbon dioxide extraction. A gas chromatograph with a mass spectrometric detector was used to determine the component composition of the extract. Antimicrobial activity was determined by two methods: the micromethod of serial dilution and the disc-diffusion method. Four microbial test strains were used: Staphylococcus aureus ATCC 6538-P, Escherichia coli ATCC 8739, Klebsiella pneumonia ATCC 10031, and Candida albicans ATCC 10231. Results. The technology of carbon dioxide extraction has undoubted advantages over traditional methods of extraction: it has a controlled selectivity in relation to groups of biologically active substances, allows deep extraction, and maximizes the release of rich complexes of compounds contained in plants. In this study, firstly, the CO2 extract was obtained under subcritical conditions from the aerial part of L. latifolium L., and the composition was determined. Hexane was the best solvent for CO2 extract, and 40 components were identified. Screening of antimicrobial activity of the L. latifolium’s CO2 extract showed the essential activity of all clinically significant strains tested: Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, and Candida albicans. Conclusions. This research showed that the CO2 extract of the raw material of Lepidium latifolium L. contains biologically active compounds exhibiting an essential antimicrobial effect, and therefore it is possible to recommend for the development of various drugs for use in medical practice.
