This study aimed to determine antimicrobial activity of extracts of Tamarindus indica L. leaves (Magyee). It was the laboratory-based quasi experimental study design. Study sites were the University of Pharmacy (Mandalay and Yangon) and the Department of Medical Research (Yangon). The leaves of Tamarindus indica L. were extracted with petroleum ether, ethanol and distilled water by successive Soxhlet extraction method. Physicochemical and phytochemical studies were conducted according to reference analytical procedures. In vitro antimicrobial activity of three extracts of Tamarindus indica L. leaves were studied on control strains of bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella pneumoniae) by agar disc diffusion method. Phytochemical analysis of Tamarindus indica L. leaves showed the presence of alkaloids, amino acids, carbohydrates, flavonoids, glycosides, polyphenol, starches, steroids/terpenoids, tannins, reducing sugars and anthroquinone. Ethanolic and aqueous extracts exhibited significant antibacterial activities against Pseudomonas aeruginosa and Staphylococcus aureus. Both aqueous and ethanolic extracts possessed promising antibacterial activity on Pseudomonas aeruginosa and Staphylococcus aureus. This was an important finding upon pathogenic organisms causing food-borne diseases, skin and soft tissue infection. The petroleum ether extract did not show antibacterial activity against all tested organisms. With ethanolic extracts, the minimum inhibitory concentrations (MIC) results were 6.25 mg/ml for P. aeruginosa, S. aureus and 25 mg/ml for E. coli. For aqueous extracts, the MIC of P. aeruginosa and S. aureus were 12.5 mg/ml and K. pneumoniae was 25 mg/ml, respectively. Oral acute administration of 5000 mg/kg mice body weight of ethanolic and aqueous extracts of Tamarindus indica L. leaves resulted in no mortality. Therefore, the crude extracts from Tamarindus indica L. leaves had antimicrobial activity against K. pneumoniae, P. aeruginosa, S. aureus and E. coli.

AbstractThe first aim of the study was to compare the antibacterial activity of several types of honey of different origins, against some bacterial resistant strains. The strains had been isolated from patients. The second aim was to discover the correlations between the antibacterial character of honey and the physico-chemical properties of the honey. Ten honey samples (polyfloral, linden, acacia, manna, and sunflower) from the centre of Romania were tested to determine their antibacterial properties against the following bacterial species: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica serovar Typhimurium, Bacillus cereus, Bacillus subtilis, and Listeria monocytogenes. Bacterial cultures in nutrient broth and the culture medium Mueller-Hinton agar were used. The susceptibility to antibiotics was performed using the disk diffusion method. All honey samples showed antibacterial activity on the isolated bacterial strains, in particular polyfloral (inhibition zone 13-21 mm in diameter) - because it is the source of several plants, and manna (inhibition zone 13-19.5 mm in diameter), and sunflower (inhibition zone 14-18.5 mm in diameter). Pure honey has a significant antibacterial activity against some bacteria which are resistant to antibiotics. Bacterial strains differed in their sensitivity to honeys. Pseudomonas aeruginosa and Staphylococcus aureus were the most sensitive. The present study revealed that honey antibacterial activity depends on the origin of the honey. We also found that there was a significant correlation between antibacterial activity of honeys and the colour of the honey but not between acidity and pH. The statistical analysis showed that the honey type influences the antibacterial activity (diameter of the bacterial strains inhibition zones).
