Conteúdo: |
Croton conduplicatus is a species popularly known in the Brazilian Caatinga (Semi-Arid vegetation) as quebra faca. Essential oils from the fresh lea ves were obtained by hydrodistillation in two different seasons (dry and rainy seasons) after 2, 3 and 4 hour s of extraction. Analyses were made by GC-MS. The main compounds found in the oil of leaves collected in the dry season were 1,8-cineole, p-cymene, spathulenol and caryophyllene oxide. For the essential oil coll ected in rainy season the major constituents identified were 1,8-cineole, -phellandrene, bicyclogermacrene, (E)-caryophyllene and spathulenol. The antioxidant potential was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis-3- ethylbenzothiazoline-6-sulfonic acid (ABTS) scavengers methods, as well as the method of co-oxidation of -carotene/linoleic acid. A significant inhibitory effect of essential oils on ABTS free radicals was detected. C. conduplicatus is a natural source of antioxidants. The essential oils from the leaves contain constituents with antioxidative properties and could serve as inhibitors or scave ngers of free radicals |
