Much effort has focused on examining the inhibitory effect of Salvadora persica (miswak) on oral microorganisms, but information concerning its antibacterial activity against other human pathogens, particularly multidrug resistant (MDR) isolates, is scarce. Therefore, this study aimed to assess the in vitro antibacterial activities of Salvadora persica L. extracts against 10 MDR bacterial clinical isolates other than oral pathogens. The antibacterial activity of aqueous and methanol miswak extracts was assessed using the agar dilution and minimum inhibitory concentration (MIC) methods. Overall, the 400 mg/mL of miswak extract was the most effective on all strains. The methanol extract exhibited a stronger antibacterial activity against Gram-negative (3.3–13.6 mm) than Gram-positive (1.8–8.3 mm) bacteria. The lowest MIC value was seen for E. coli (0.39, 1.56 µg/mL), followed by Streptococcus pyogenes (1.56 µg/mL). The highest MIC value (6.25, 12.5 µg/mL) was recorded for methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter baumannii, and Stenotrophomonas maltophilia. This study demonstrates, for the first time, the moderate to strong antibacterial activity of miswak extracts against all tested MDR-pathogens. Methanol extract appears to be a potent antimicrobial agent that could be considered as complementary and alternative medicine against resistant pathogens. Further studies on a large number of MDR organisms are necessary to investigate and standardize the inhibitory effect of miswak extracts against these emerging pathogens.

This study determines the antimicrobial efficacy of miswak (aqueous and alcoholic) extracts comparing with five different toothpastes, which are available in Iraqi market, against different kinds of bacteria. The antibacterial efficacy of aqueous and alcoholic extracts of Salvadora persica and different kinds of toothpastes was studied against different cariogenic and pathogenic bacteria including Streptococcus mutans, Lactobacillus acidophilus, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa by well diffusion method. Salvodora persica extracts and toothpastes exhibited the greatest antimicrobial activities towards Staphylococcus aureus, Streptococcus mutans, Lactobacillus acidophilus, E. coli and Pseudomonas aeruginosa respectively. Alcoholic extract was dominant on aqueous extract in inhibiting the tested microorganisms. Toothpastes A were dominant comparing with the other toothpastes in inhibiting the tested microorganisms. The impact of toothpastes was almost more than Salvodora persica extracts on tested microorganisms. According to the good efficacy of Salvodora persica extracts on the tested microorganisms, it has antibacterial effects and could be used as a therapeutic agent and therefore, it appears to be a potent antimicrobial agents that could be considered as a medicinal plant.

“…Their function in plants is now most interest as some appear to have a key role in protecting plants from herbivores and microbial infection. These compounds are also used as dyes, fibres, glues, oils, waxes, flavouring agents, drugs and perfumes and they are viewed as potential sources of new natural drugs, antibiotics, insecticides and herbicides (Buchanan et al, 2000;Dewick, 2002;Gomez-Flores et al, 2006). Medicinal plants have been the essential for health care throughout the world since the earliest centuries and are still widely used right now.…”

Problem statement: Many species of plants in Malaysia are widely used in folk medicine. However, Calophyllum species have been used in traditional medicine for their therapeutic values for many years. Several studies reported that antimicrobial, antifungal, anti-HIV and anti-cancer compounds were isolated from numerous Calophyllum species. Approach: The stem bark was extracted by EtOH, after with it was fractionated with n-Hexane, Dichloromethane (DCM) and MeOH by using vacuum liquid chromatography apparatus. Phytochemical contents were examined to evaluate the phinolic, flavonoid and flavonol contents. Also the antimicrobial activity was carried out by using disc diffusion and dilution method to evaluate antimicrobial activity of the crude and the fractions respectively. Six references microbial strains of human pathogens were used for examined the anti microbial activity. The two Gram-positive bacteria (Staphylococcus aureus, Bacillus cereus) and two Gram-negative (Pseudomonas aeruginosa, Escherichia coli) were used for antibacterial test. Also two fungal strains (Candida albicans and Cryptococcus neoformans) were used for antifungal test. Results: Although the C. rubiginosum has phytochemicals as all plants, but it was showed a high content of flavonol in the range of 11.9-15.2 µg mL −1 . The C. rubiginosum fractions were showed no activity against gram negative and fungus. However, the non polar and semi polar fractions were showed a result MIC 12.5 µg mL −1 against B.cereus bacteria. While the MeOH fraction indicated for low or no activity against bacteria and fungus. Conclusion: At last, the optimistic result of this study encourage us to go forward for further studies in the future to isolate the active compound of the stem bark of C. rubiginosum, where it could lead to a new antibiotic, whereas this species never investigated before.
