BELTRAN CIFUENTES, Martha Cecilia; CANTILLO MALDONADO, María Pía  e  VIVAS CASTANO, Andrea Maritza. ntibacterial activity of oils from Ocimum basilicum L. var. cinammom, O. album O. thyrsiflorum, for potential use in phytocosmetics. Investig. andina [online]. 2013, vol.15, n.27, pp.798-810. ISSN 0124-8146.

Introduction: the species Ocimum basilicum L., in the varieties: cinammom, album, thyrsiflorum have been reported by GC-MS by their high content of oxygenated monoterpenes and phenylpropans as: p-eugenol, E-Z methyl cinnamate, eucalyptol and linalool. Pharmacognosis studies indicate that these compounds are characterized by antimicrobial activities. Methods: essential oils (EOs) were obtained by distillation Clevenger-type steam stripping, dried with sodium sulfate anhydrous, and hermetically preserved under refrigeration. The antimicrobial activity of the EO was performed by the broth dilution method to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) from fold serial dilutions in a concentration range from 3,12 to 0,1%, and these concentrations were faced with Staphylococcus aureus, Escherichia coli, Pseudomona aeruginosa and Salmonella typhimurium. Results: essential oils (EOs) of the species Ocimum basilicum L. var. cinammom showed inhibitory activity against Staphylococcus aureus, Escherichia coli and Salmonella typhimurium, but not against Pseudomonas aeruginosa, the results showed the same percentage for the concentration of EO as a MBC and MIC. The EOs of the species Ocimum basilicum L. var. album and Ocimum basilicum L. var. thyrsiflorum showed inhibitory activity at the same concentrations of OEs against Staphylococcus aureus and Escherichia coli, both varieties showed the same MIC and MBC against E. coli. Conclusion: these results obtained demonstrate the ability of OEs to inhibit the growth of certain pathogen microorganisms, which allows considering it as a potential source of phytocosmetics field, which has been reported for use in the manufacture of products for the treatment of acne, manufacture of shampoo, toners and masks.
