Objective: To study in vitro antibacterial and antifungal activity of hot water and methanolic extracts of the three medicinal plants-Boswellia (Luban) species. Methods: Three selected plants were collected from different localities of Soqotra (Republic of Yemen), Dohfar (Sultanate of Oman) and Republic of Somalia. The plants were dried and extracted with two different solvents (methanol and hot water) to yield six crude extracts. The obtained extracts were tested for their antibacterial activity against eleven different bacterial strains and two fungi using the standard well-diffusion and micro-dilution methods. The following microorganisms were used: methicillin-resistant Staphylococcus aureus (ATCC 6538), muti-drug resistant Pseudomonas aeruginosa (ATCC 27853), enterohemorrhagic Escherichia coli (0157 EHEC), Salmonella typhi, Proteus vulgaris, Klebsiella pneumoniae, Bacillus subtilus (ATCC 6059, reference strain), Streptococcus pneumoniae, Klebsella pneumonia, MRSA, Corynebacterium, Corynebacterium diphtheriae and two fungus: Candida maltosa and Candida albicans. Results: The different extracts possessed different inhibitory activity against different types of bacterial species. The patterns of inhibition varied with the plant extract, the solvent used for extraction and the organisms tested. The antimicrobial activity exhibited by the methanolic extracts of Boswellia sacra from the Suqotra and Dhofar regions was greater than that of Boswellia frereana collected from Somalia. The methanolic extract of the oleo-gum-resin showed higher efficacy to inhibit all the tested bacterial strains than the methanolic extract of frankincense-resin. The Boswellia frereana collected from Somalia showed lower activity compared with the two other Boswellia species. The plant extracts showed bacteriostatic activity at lower concentrations and bactericidal activity at higher concentrations. Neither water nor methanolic extracts showed any activity against the fungi Candida maltosa and Candida albicans. Conclusions: It can be concluded that the methanolic extracts of Boswellia (Luban) possess the highest antibacterial activity. Neither water nor methanolic extracts show any activity against Candida maltosa and Candida albicans.
