Aroma Components and Antioxidant Activities of Pure Lavender Essential Oil Goods in Different Produced Countries

摘要

The internal and external circulation of pure (100%) lavender (Lavandula angustifolia Mill.) essential oils (EO) were collected from 33 kinds produced different countries. These samples were analyzed of its aroma components and measured of the antioxidant activity. As the result of analyzing the components of lavender EO including linalool, linalyl acetate, pinene, camphene, camphor, and borneol were identified. Main components (linalool, linalyl acetate) content difference of lavender essential oilappeared by Australia> France> Not marked origin> etc> South Korea. However, all samples weren't met requirement of ISO lavender standard. Electron donating ability (EDA) in the 2.6 to 94.0% contents showed significant differences. EO produced in Australia, France, Switzerland, Germany, and Korea was more than 50% of antioxidant activity. Most of EOs that have high contents of linalool and linalyl acetate showed high antioxidant effect. By comparing antioxidant activity according to the listed place oforigin, it showed highest antioxidant activity from the EO produced in Australia. The high antioxidant activity of 52.1% of EO cultivated and extracted in Korea, despite the low content of linalool and linalyl acetate content of EDA (%), could be considered that the beta-phellandrene, which is the monoterpene component is contained in large composition.
