【 摘 要 】

Introduction:medicinal and aromatic plants have potential as sources of antioxidant compounds. There is a great diversity of native species in Patagonia Argentina. It is worthy to study them because of its pharmaceutical potential and to help promote conservation.Objectives:to analyze antioxidant activities of herbal teas, tinctures and essential oils of native species from Patagonia Argentina: Acantholippia seriphioides (A. Gray) Moldenke, Adesmia boronioides Hook. f., Buddleja globosa Hope, Fabiana imbricata Ruiz & Pav., Solidago chilensis Meyen. Identify essential oils compounds.Methods:infusions and tinctures were obtained according to Pharmacopoeia Argentina VIth edition. The essential oils were obtained by hydrodistillation in a Clevenger apparatus. Volatiles compounds were analyzed by gas chromatography-mass spectrometry. Antioxidant activity assays were performed by difenil-picrilhidrazilo method.Results:antioxidant activity order was: B. globosa > S. chilensis ≥ F. imbricata ≥ A. seriphioides > A. boronioides. Infusions of B. globosa, S. chilensis and A. seriphioides presented an antioxidant activity similar to Camellia sinensis (L.) Kuntze ("green tea") and higher than Ginkgo biloba (L.) Mant. The A. seriphioides essential oil activity was probably obeyed to thymol and carvacrol presence. S. chilensis activity could be owing to its high limonene content.Conclusions:this study is the first report about antioxidant activity of medicinal and aromatic plants in the northwest region of Patagonia Argentina. The results showed that analyzed species are a rich source of antioxidant compounds and have potential value as a dietary supplement.
