Biological Bioactivities, Physicochemical Properties, Atomic Absorption and Antibacterial Activity of Rosemary (Rosmarinus officinalis L.) Aromatic Plant in Al- Baha Area

Rosemary (Rosmarinus officinalis L.) is aromatic plant a widely used in traditional and folk medicine, Gas Chromatography-Mass Spectrometry (GC-MS) used to identify the bioactive phytochemical constituents, 42 compounds identified in this study, 16 are the major compounds. In this study also were evaluating the physicochemical properties of Rosemary such as peroxide value (2.35 meq O2/kg, acid value as oleic acid (1.122 mg KOH/g), iodine value 85 mg / 100 mg, saponification value of 220 mg KOH / g of Fat, pH (5.7), refractive index (1.39 and at 28°C), viscosity (CST) (68.33), specific gravity, 1.489 and density (0.92 g/cm3). Atomic absorption was used to identify minerals content in rosemary, contains Copper 11.4 ppm, Ferric 250 ppm, Zinc 12.85 ppm.The effect of Rosemary oil in four different pathogenic bacteria Bacillus cereus, Pseudomonas aeruginosa, Escherichia coli, and Salmonella typhimurium, were examined using Mueller Hinton Agar and measuring inhibition zone (diameter mm), were found that, there were a significant different of Rosemary oil against bacteria.
