Los Productos Forestales No Madereros (PFNM), definidos como "bienes de origen biológicos distintos de la madera, provenientes de los bosques", han experimentado un aumento sostenido en su consumo por parte de la sociedad en estas últimas décadas, en especial la categoría de alimentos y especies medicinales, valorados por su condición de bien de origen silvestre, natural y con impacto significativo en la salud y en el contexto de la alimentación sana. Con el objetivo de contribuir a este conocimiento, así como a la protección y conservación de los recursos del país, al rescate de la cultura de la recolección y a la generación de nuevas oportunidades de negocios, el Instituto Forestal (INFOR), a través de su Programa de Investigación sobre PFNM, entrega este documento antecedentes preliminares para poner a disposición de todos quienes quieran explorar y emprender en forma sustentable, en este interesante ámbito de los productos forestales no madereros

Alkaloids derived from plants have shown great medicinal benefits, and are often reported for their use in cardiovascular disease management. Aristotelia chilensis (Molina) Stuntz (Maqui) has shown important medicinal properties in traditional useage. In this study, we evaluated the effect of the indole-alkaloid aristoteline (ARI), isolated from leaves of Maqui, on vascular reactivity of isolated aortic rings from normotensive rats. ARI induced relaxation (100%) in a concentration-dependent manner in intact or denuded-endothelium aortic rings pre-contracted with phenylephrine (PE; 1 μM). However, a specific soluble guanylyl cyclase inhibitor (ODQ; 1 μM) significantly reduced the relaxation to ARI in aortic rings pre-contracted with PE. In the presence of ARI, the contraction induced by KCl or PE was significantly (p < 0.05) decreased. Interestingly, the potassium channel blockade with 10 μM BaCl2 (Kir), 10 μM glibenclamide (KATP), 1 mM tetraethylammonium (TEA; KCa1.1), or 1 mM 4-aminopyridine (4-AP; Kv) significantly (p < 0.05) reduced the ARI-induced relaxation. ARI significantly (p < 0.05) reduced the contractile response to agonist of CaV1.2 channels (Bay K8644; 10 nM), likely reducing the influx of extracellular calcium through plasma membrane. The mechanisms associated with this process suggest an activation of the potassium channels, a calcium-induced antagonism and endothelium independent vasodilation that possibly involves the nitric oxide-independent soluble guanylate cyclase pathway.
