Antioxidant activities of essential oils from anise (Pimpinella anisum L.), fennel (Foeniculum vulgare Mill.), coriander (Coriandrum sativum L.), rosemary (Rosmarinus officinalis L.), oregano (Origanum vulgare L.), ylang-ylang (Cananga odorata Hook.), verbena (Lippia alba Mill.) and salvia negra (Lepechinia schiedeana (Schlecht) Vatke, syn. Stachys schiedeana Schlecht) were determined using the free radical ˛-˛- diphenyl-ˇ-picrylhydrazyl (DPPH ž ) and the preformed radical monocation 2,2 0 -azino-bis(3-ethylbenzothiazoline- 6-sulphonic acid) (ABTS žC ). Some of the oils under investigation had antioxidant capacities in a range comparable to that of ˛-tocopherol, BHA, ascorbic acid and Trolox, which were used as reference antioxidants. The all- liquid chromatographic technique of multilayer coil countercurrent chromatography (MLCCC) was applied to the fractionation of oregano essential oil. For oregano, a high antioxidant activity was observed, which is mainly due to the presence of thymol and carvacrol in the essential oil. Copyright 2002 John Wiley & Sons, Ltd.
