The effect of autoxidation of lemon‐grass oil on its antibacterial activity has been studied. Using the Active Oxygen method, the oil was found to undergo rapid oxidation under accelerated test conditions. The oxidized oil samples were found to have reduced activity against bacteria. This activity was completely lost in extensively oxidized oil samples. Inclusion of antioxidants in the oil samples reduced the rate of oxidation and enhanced the antibacterial activity of the oil. The effects of the antioxidants were concentration dependent, and at their effective concentrations, oxidation was completely prevented for the period of the test.
