Component Analysis and Antibacterial Activity of Basil Essential Oil
Analysis of main components and quantitative analysis of antibacterial composition of basil essential oil are conducted by using gas chromatography-mass spectrometry (GC-MS).Stability analysis of supermarket fresh light beam and pH value on antibacterial components is studied by ultraviolet spectrophotometry.Antibacterial effect of basil essential oil is determined by filter paper diffusion method.Through the observation of change of cell by using scanning electron microscope (SEM),the bacteriostatic mechanism of basil essential oil is explored.The results show that the main antibacterial composition of basil essential oil is eugenol whose absolute content is 0.9734 g/mL.Light has little influence to the stability of eugenol.It has good stability if the solution pH value is in the range of 5~8.Basil essential oil has significant inhibition on Escherichia coli and Staphylococcus aureus by breaking the integrity of cell.
