Description To study the phytochemical profile, antimicrobial and antioxidant activity of essential oils obtained from Boswellia
ovalifoliolata (BO) leaf, stem bark and gum resin samples. Phytochemical profiles of the three essential oils were analyzed by
GC-MS, antimicrobial activity was performed against two Gram positive, two Gram negative and two fungal species by using
disc diffusion method. Minimum inhibitory concentrations were assayed by micro dilution method. Further, antioxidant
capacity of three oil samples were determined by DPPH scavenging method. Gas chromatographic analysis of BO three
essential oil (EO) samples revealed that 30 compounds were identified in leaf oil and 25 compouds in each were identified in
stem bark and gum resin EOs. The results showed that 11 compounds i.e. α –amarphene, δ-cadinene, caryophyllene oxide,
caryophyllene, β-farnesene, α-humulene, ledol, γ-murrolene, β-myrcene β-pinene, and (-)-zingiberene were common
compounds in three oil samples. Three essential oils showed good antimicrobial activity against test pathogens. Among the
tested pathogens, Candida rugosa found to be most sensitive organism to leaf, stem bark and gum EO samples, while Gram
positive bacterium Bacillus subtilis was most resistant organism to the test oils. Further, the oil samples showed concentration
dependent DPPH reducing capacity. The present study revealed that, the essential oils of BO exerts beneficial effects to inhibit
human pathogenic microorganisms and as a source of natural antioxidant compounds.
