Antibacterial Evaluation and GC-MS Analysis of the Essential Oil from Botanically Certified Oleo Gum Resin of Boswellia Sacra (Sudanese Luban)

The aim of the present study is to assess the phytochemical screening, investigate the chemical constituents of the Essential Oil from Boswellia sacra Seeds and to evaluate its potential antibacterial activity. Using the Soxhlet method to extract the essential oil from Sudanese Luban Seeds. The chemical constituents of Sudanese Luban Oil were identified and quantified by GC-MS, where the paper disc diffusion assay was employed to evaluate the antibacterial activity. Phytochemical screening showed that Alkaloids, Flavonoids, Triterpens, Streols, Tannins and phenolic compounds are present in Boswellia sacra (Sudanese Luban). Twenty five components have been identified. Nine of them are major namely; Hexadecanoate methyl ester (16.08%); 9,12-Octadecadienoate (Z,Z)-methyl ester (21.03%); 9-Octadecenoate (Z)- methyl ester (12.58%); Methyl stearate (14.40%); E,E-3,13-Octadecadien-1-ol (4.54%); Oxiraneoctanoic acid, Octyl -,methyl ester (3.88%); Eicosanoic methyl ester (7.33% ); Docosanoic acid, methyl ester (8.15%); Tetracosanoic acid, methyl ester (3.13%). The antibacterial showed a high inhibitory effect against Escherichia coli (17mm), Pseudomonas aeruginosa (16mm), Bacillus subtilis (15mm), moderate against Bacillus subtilis (14mm) and inactive against Candida albicans. In conclusion, the Essential Oil from Boswellia sacra Seeds a good source of natural antibacterial, and justify its uses in folkloric medicines.
