Análisis botánicos y fitoquímicos comparativos de una especie aromática y medicinal endémica de la Patagonia (ADESMIA BORONIOIDES HOOK.F.) Introducida a cultivo.

Abstract

Adesmia boronioides Hook. f. is an interesting medicinal and aromatic species because of the numerous properties attributed to it, some of them even partially assessed, and besides on account of its high quality essential oil with an emerging commercial interest. Native plant uses requires a domestication and standardization of active principles, necessary to production, process and utilization as well as the uniformity of crops. Morphological and chemical studies were made on natural populations and cultivated from seeds of A. boronioides obtained near Bariloche city, Argentina. Length of leafs and pairs of leaflets were higher in cultivated plants. Conversely natural populations had higher amounts of essential oils than cultivated ones. Chemical composition was very similar from both sources, but concerning essential oil´s quality, both provenances were equally interesting, slightly cleaner and more harmonious the cultivated one. Plants from experimental crops showed higher antioxidant activity and total phenol contents. The confirmation of morphological and chemical results will require further studies to assure these characteristics are retained over time.
