Lemon and eucalyptus oils were known to have various biological effects such as anti-aging and sterilizing action. However these essential oils were not well studied about their antioxidant activity and antimicrobial activity against specific skin flora. In this study, we investigated antioxidant activity and antimicrobial activity of lemon and eucalyptus oils by using DPPH radical scavening activity and paper disc method. Lemon oil showed the high DPPH scavenging activity, while eucalyptus oil did not. Blending oils of lemon and eucalyptus had little enhancememt on antioxidant activity. Paper disc method demonstrated that each oil had a high antimicrobial effect against C. albicans and P. acnes in a concentration dependent manner. The blending oils had enhancememt on antimicrobial effect against P. acnes. In conclusion, the blending oil of lemon and eucalyptus can be used as a more effective natural agents for cure of skin trouble and acne.
