국내 자생식물로부터 얻어진 천연정유 추출물의 항산화 효과에 대한 연구 = Antioxidant Activities of Natural Essential Oils Derived from Korean Endemic Plants

다국어 초록 (Multilingual Abstract)

Oxidative stress, which is induced by free radicals, causes various pathophysiological problems in the body. Natural essential oils derived from aromatic plants such as lavender and rosemary are used as additives in foods and cosmetics because of their aroma and antioxidant effects. The purpose of this study was to investigate the antioxidant activity of natural essential oils from Korean endemic plants. Natural essential oils including Mentha piperascens, Teucrium veronicoides, Citrus unshiu Peel, Angelica gigas Nakai, Zingiber officinale Roscoe, Artemisia annua L., Houttuynia cordata Thunb, Dendranthema zawadskii var. latilobum, Chrysanthemum morifolium, and Atractylodes macrocephala Koidz. were extracted by steam distillation extraction method, respectively. 2,2-Diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline- 6-sulphonic acid) methods were performed to measure the free radical scavenging activity of each essential oil. We found that the essential oils from the Asteraceae family including Dendranthema zawadskii var. latilobum and Chrysanthemum morifolium showed more potent antioxidant activity than those from other plants. Our findings suggest that natural essential oils derived from Asteraceae family have free radical scavenging activity, which may be explored in the prevention of health problems.
