Abstract
Cetraria Islandica es una especie de liquen de las zonas montañosas y frías de Europa que es usado tradicionalmente en afecciones respiratorias y digestivas. Actualmente se han empezado a hacer más estudios sobre él, descubriendo su actividad antioxidante, antidiabética, antiinflamatoria y anticancerígena, que junto a otros líquenes les está haciendo ganar popularidad entre la población. En los herbolarios se vende liquen de Islandia o musgo de Islandia en forma de extracto, infusiones o plantas desecadas. Ya que en España se da la venta libre de plantas medicinales y este liquen es de difícil acceso, se ha querido comprobar si se realizan falsificaciones o adulteraciones de él. Para ello se ha realizado la técnica de identificación molecular y código de barras de ADN (ADN barcoding)que ha demostrado mayor eficacia a la hora de clasificar e identificar las muestras de líquenes, debido a su increíble parecido tanto morfológico como químico entre especies del mismo género que dan lugar a errores.
Cetraria Islandica is a lichen species from cold mountain areas of Europe that is traditionally used in respiratory and digestive disorders. Currently, there has been made advances on its uses specifically discovering its antioxidant, antidiabetic, antiinflammatory and anticarcinogenic activity, which together with other lichens is making them gain more popularity among the population. The Iceland lichen or Iceland moss is sold in the herbalist as extracts, infusions or dried plants. Because in Spain there is an open sale of medicinal plants and this lichen is difficult to get, we wanted to test if any forgery or adulteration has been made. In order to reach the goal, we have used molecular identification technique including DNA barcodings. This technique has been proved to be more effective for sample identification and classification in lichens than the morphological or chemical based approach, due to its incredible resemblance between species and morphological convergence.
