Bioactivity of Essential Oils of Species of the Lamiaceae Family | Chapter 1 | Current Innovations in Medicine and Medical Science Vol. 4

 Important medicinal, aromatic, and condiment plants used in both traditional and modern medicine are members of the Lamiaceae family. The biological properties of essential oils point to possible therapeutic possibilities, such as antibacterial and antioxidant properties and applications in a range of industries. The essential oils of Lavandula angustifolia, Pogostemon cablin, Rosmarinus officinalis, and Thymus vulgaris were tested for their antibacterial, antioxidant, and yield properties against Staphylococcus aureus, Salmonella enteritidis, Escherichia coli, and Pseudomonas aeruginosa. The experiment was carried out in Brazil's Federal University of Technology - Paraná's microbiology lab. The essential oils were examined using mass spectrometry and gas chromatography. The least inhibitory and bactericidal concentrations were discovered using microdilution in broth to determine antibacterial activity. Through the scavenging of the 2,2-diphenyl-1-picryl hydrazyl radical, the antioxidant activity was assessed (DPPH). Essential oil yields from L. angustifolia, P. cablin, R. officinalis, and T. vulgaris were, respectively, on the average, 0.85, 2.0, 1.20, and 1.19 percent. Linalyl acetate (40.1%) and linalool (35.2%) were the two main constituents of lavender essential oil, whereas patchoulol (31.5%), seichelene (13.6%), and -bulnesene (15.6%) were found in P. cablin, camphor (32.5%), 1.8-cineole (13.6%), and -pinene (9.8%) were found in rosemary, and thymol (47%), o-sc Thyme oil had the highest levels of antibacterial activity, and because it contains phenolic compounds that are effective against a wide range of pathogens, very small amounts (0.195 L mL-1) of the minimum inhibitory concentration were needed to inhibit S. aureus and S. enteritidis. We found that to suppress the bacteria tested, large quantities of the essential oils from L. angustifolia, P. cablin, and R. officinalis were required. The crucial
