RESUMEN: La Renealmia alpinia (matandrea o achira de monte) es una planta que por sus efectos antiedematizantes, antihemorrágicos y neutralizantes del veneno de la serpiente Bothrops asper (mapaná equis), se constituye en una potencial alternativa de atención primaria en accidentes ofídicos, o en una fuente de moléculas con importancia farmacéutica. A pesar de ello, no existen estudios previos encaminados a la propagación vegetativa, la desdiferenciación tisular o la producción in vitro de sus metabolitos. En este trabajo se evaluan bajo condiciones in vitro algunas variables como la altura, el número de brotes y raíces en la propagación de R. alpinia, así como la tasa de velocidad de multiplicación y la inducción de tejido indiferenciado en explantes foliares. La adición de 6- Bencilaminopurina (3 mg/L) promueve la propagación de esta especie vegetal, con una tasa de velocidad de multiplicación (TVM) de 1.39 brotes/semana, mientras que la inducción de tejido indiferenciado se ve favorecida por la exposición de los explantes foliares a la combinación de 2,4-D (2 mg/L) y BA (1mg/L). Adicionalmente, se detecta en el tejido foliar (de plantas crecidas in vitro y ex vitro) la presencia de cumarinas, metabolitos encontrados en algunas plantas con conocida actividad antiofídica, abriendo así la posibilidad de estudios encaminados a la producción y evaluación in vitro de estos y otros metabolitos con potencial interés farmacéutico.
ABSTRACT: Renealmia alpinia (matandrea or achira de monte) it`s an important plant for their neutralizing ability of both effects oedema-forming, hemorrhagic and clotting of the venom of the snake Bothrops asper (mapaná equis). It is a potential alternative of primary attention in ofidic accidents, or like a source of molecules with pharmaceutical importance. Despite this, there is not previous studies on this specie guided to micropropagation, tissular dedifferentiation or in vitro metabolites production. In this work was evaluated some variables as the height, the number of shoots and roots in the propagation of R. alpinia under in vitro conditions, as well as the rate of speed multiplication and the induction of having undiferentiated tissue in foliar explants. Addition of 6-Bencylaminopurine (3 mg/L) promotes the propagation in vitro, with a rate of speed multiplication (TVM) of 1.39 shoots/week, while the induction of having undiferentiated tissue in foliar explants was favored by both 2,4-D (2 mg/L) and BA (1mg/L)in combination. Additionally, was detected in foliar tissues (of grown plants in vitro and in vitro) cumarins, its metabolites has been found in some plants with well-known antiofídic activity, this results open possibilities of studies in order to the production and in vitro activity evaluation of metabolites with potential antiofidic activity or pharmaceutical interest.
