Bacterial resistance develops due to overuse of antibiotics in addition to the adverse effects of these chemicals. This urges the scientists to exchange these antibiotics with alternatives from natural products. The study aimed to evaluate the antimicrobial efficiency of Arum cyrenicum Hruby against a number of medically important pathogenic bacteria. A. cyreniacum corms extracted with petroleum ether, chloroform and methanol, and tested for antimicrobial activity against Escherichia coli BTC3, Salmonella typhi BTC10, Pseudomonas aeruginosa BTC4, and Staphylococcus aureus BTC15. A considerable bactericidal efficiency of petroleum ether extract of A. cyrenaicum corms were specifically against gram-positive bacteria, Staphylococcus aureus BTC15 at (100 mg/ml) petroleum ether and bacteriostatic at (50 mg/ml) of petroleum Ether extract. Whereas, the methanolic extract of A. cyrenaicum corms had bactricidal effect against gram-negative bacteria, Pseudomonas auregenosa BTC4 at (100mg/ml) of methanolic extract. Herby our results indicate that petroleum ether and methanolic extracts of A. cyrenaicum possess significant antibacterial properties. Keywords: Arum cyrenicum, Efficiency, Antibacterial

The aim of the present study was to investigate phytochemical and antibacterial potential of Calendula officinals L. and Catharanthus roseus L. G. Don leaves. The leaves of both plants were screened for physico-chemical analysis. Phytochemical screening was carried out to find phytoconstituents and subsequent antibacterial studies of extracts were carried out against the pathogenic bacterial strains Bacillus cereus, Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Salmonella typhi using Kirby bauer method. The extract with maximum antibacterial activity was further processed for TLC studies. The results of the present investigation revealed superiority of C. roseus over C. officinalis in terms of ash value. Both plants showed the presence of alkaloids, saponnins, tannins, phenolic compounds, flavonoids and carbohydrates. The antibacterial studies revealed that the petroleum ether extract of C. officinalis has been active against all strains, whereas the same extract of C. roseus showed activity against S. typhi, S. aureus and B. subtilis. Chloroform extract of C. officinalis was active against only two strains i.e. E. coli and B. subtilis. Methanolic and aqueous extracts of both plants were also found to be active against all strains. Studies of TLC analysis revealed that petroleum ether extract of C. officinalis and methanolic extract of C. roseus showed distinct RF values. Further studies are required to separate characterize and screen these components for therapeutic purposes.

Cyperus rotundus L. belongs to the family Cyperaceae. It is used to treat constipation, stomach disorders, dysmenorrhea, skin diseases, wounds, leprosy, fever, etc., in indigenous medicine. Also, they are used to treat itchy pus-filled pimples in Sri Lanka. This study aimed to evaluate in vitro antibacterial activity of different solvent fractions and essential oil of Cyperus rotundus L. rhizomes. Soxhlet apparatus was used to obtain the methanolic and petroleum ether extracts from rhizomes, and essential oil was extracted using steam distillation. The antibacterial activity of extracts and essential oils was determined against Staphylococcus aureus and Pseudomonas aeruginosa using the agar disc diffusion method. The activity was compared with Gentamycin as standard. The activity of extracts and essential oil were compared with one-way ANOVA followed by Dunnett's test. The results showed that both extracts and essential oil of Cyperus rotundus L. rhizomes showed a statistically significant difference in antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa compare to the standard drug, Gentamycin. The essential oil of Cyperus rotundus L. rhizomes showed comparatively higher antibacterial activity than extracts. Staphylococcus aureus was more susceptible to methanolic extract and essential oil than petroleum ether extract. Pseudomonas aeruginosa was more susceptible to essential oil and petroleum ether extract than methanol extract. Cyperus rotundus L. rhizomes possess good antibacterial activity, and further studies are required to isolate active phytochemicals and screen for antimicrobial activity

Aims: The present investigation was aimed at exploring the phytoconstituents using Gas Chromatography Mass Spectroscopy and to evaluate antioxidant and anti-inflammatory properties of the leaf extracts. Materials and Methods: The extracts were obtained sequentially with petroleum ether, ethyl acetate and water using soxhlet apparatus. The anti-inflammatory property of the identified compounds using GC- MS spectroscopy was evaluated in silico. The antioxidant activity was performed by DPPH and H2O2 method whereas anti-inflammatory study was carried out by HRBC membrane stabilization method. Terpenoids were found to be major constituents in petroleum ether extract while, phenols and flavonoids were predominantly found in ethyl acetate extract. Results and Discussion: The GC-MS analysis of the extract revealed six major molecules including Squalene, 19β, 28- epoxyleanan-3-ol and 2-tu-Butyl-5-chloromethyl-3-methyl-4-oxoimidazolidine-1-carboxylic acid. The ethyl acetate extract showed a significant antioxidant activity (P<0.01) in both DPPH method (70.87 %) and H2O2 method (73.58%) at 200 µg mL-1 . Increased membrane stabilization of petroleum ether extract was observed in the in vitro anti-inflammatory activity study. A strong relationship between the terpenoid content and anti-inflammatory activity was obtained from the correlation (0.971) and docking study. Conclusion: These results justify T. involucrata to be a rich source of terpenoids with potent antiinflammatory property.

Cow’s milk containing pathogenic bacteria is an important threat to the consumers. The objectives of the present study were to identify the bacterial agents of public health importance in milk samples (n=35) of different locations and to determine their sensitivity to different antibiotics. The milk samples were collected and transported aseptically and subsequently allowed for culture in bacteriological media, Gram’s staining and biochemical tests for the identification of bacterial species. The bacteria identified were Staphylococcus aureus, Escherichia coli and Salmonella typhi, and their prevalence, in case of vendor milk specimens (n=28), were 96.43%, 53.57% and 35.71% respectively, and of brand milk specimens (n=7), were 42.86 %, 28.57% and 0%, respectively. This suggests that cautionary measures should be taken for quality milk production and consumption. The antibiotic sensitivity test was done by disc diffusion method and the average inhibition zones, in case of Staphylococcus aureus, were 32 mm for oxytetracycline, 26 mm for amoxicillin, 35 mm for ciprofloxacin, 27 mm for cefotaxime, 30 mm for ceftriaxone, 30 mm for azithromycin, and 26 mm for erythromycin; in case of Escherichia coli, were 5 mm for oxytetracycline, 9 mm for amoxicillin, 22 mm for ciprofloxacin, 30 mm for cefotaxime, 31 mm for ceftriaxone, 15 mm for azithromycin, and 0 mm for erythromycin; in case of Salmonella typhi., were 25 mm for oxytetracycline, 24 mm for amoxicillin, 38 mm for ciprofloxacin, 31 mm for cefotaxime, 34 mm for ceftriaxone, 24 mm for azithromycin, and 0 mm for erythromycin. Therefore, ciprofloxacin and ceftriaxone may be the antibiotics of first choice, and cefotaxime and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.Asian J. Med. Biol. Res. December 2015, 1(3): 457-462
