          RESUMEN Los estudios realizados en los últimos años sobre la actividad farmacológica y biotecnológica de las proteasas de cisterna nos han impulsado a explorar nuevas fuentes naturales de proteasas vegetales. En el presente trabajo hemos estudiado las cisteína-proteasas contenidas en el látex de Ficus spp. Esta es una especie de planta ampliamente utilizada en Bolivia y Perú por su látex, recolectada para los fines actuales en Iquitos, Perú (P-IQ), provincia de Sud Yungas (B-SY), Charcas II (B-SY), Los Olivos (B-SY), Hernández (B-SY) y en la Provincia. Abel Iturralde (B-AI), Buena Vista (B-AI), el Tigre (B-AI) en el norte de La Paz, Bolivia. En el presente trabajo establecimos la actividad proteolítica de las muestras con una correlación con el lugar de origen, la influencia del pH en la actividad proteolítica y el contenido proteico de las muestras.

          ABSTRACT The studies carried out in recent years on the pharmacological and biotechnological activity of cysteine proteases have impelled us in exploring new natural sources of plant proteases. In the present work we have studied the cysteine proteases contained in the latex of Ficus spp. This is a plant species widely used in Bolivia and Peru for its látex, collected for the present purposes in Iquitos, Peru (P-IQ), Sud Yungas Province, Charcas II (B-SY), Los Olivos (B-SY), Hernández (B-SY) and in the Province Abel Iturralde (B-AI), Buena Vista, el Tigre, (B-AI) in northern La Paz, Bolivia. In the present paper we established the proteolytic activity of the samples with a correlation to the place of origin, the influence of the pH on the proteolytic activity as well as the proteic contents of the samples.

            On the origin of the fig: phylogenetic relationships of Moraceae from ndhF sequences.

            The majority of species in the mulberry family (Moraceae) are figs (Ficus), marked by a specialized inflorescence (syconium) and an obligate mutualism with pollinating fig wasps. Because of the unique morphology of the syconium, it has been difficult to investigate the evolutionary position of the fig. We sequenced the chloroplast gene ndhF to examine relationships in Moraceae and to elucidate shifts in reproductive traits. The reclassification of tribes is warranted, and the limits of Artocarpeae, Moreae, and Castilleae are revised to reflect evolutionary relationships. The results point to ancestral dioecy in Moraceae and multiple origins of monoecy, androdioecy, and gynodioecy. Ancestral wind pollination gave way to insect pollination at least twice. Strong support for the sister-group relationship of a revised Castilleae with Ficus suggests that entomophily and involucral bracts encircling the flowers preceded the evolution of the syconium. Bracts surround flowers in Castilleae only during early development, but in Ficus the involucre and the receptacle enclose the fruit as well. Molecular dating suggests that fig pollination is at least 80-90 million years old. The diversity of Ficus relative to its sister group is a likely consequence of ancient specialization and cospeciation with pollinating fig wasps.

              Medicinal plants uses of the Tacana, an Amazonian Bolivian ethnic group.

              We present the results of an ethnopharmacological investigation of a Bolivian lowland ethnic group, the Tacana. The Tacana have a long tradition of exchange with highland communities. Though facing rapid acculturation, highlighted by the loss of the Tacana language among the younger generations, the knowledge and uses of medicinal plants are still alive. Of the approximately 450 different plant species collected during this survey, 33% had medicinal uses. We present an overview of the traditional Tacana ethnomedicine and pharmacopoeia.
