“…Se utilizan principalmente especies como: Psidium guajava, Cymbopogon citratus, Pseudogynoxys chenopodioides, Guazuma ulmifolia, Hamelia patens y Phyla dulcis. Esta tendencia se ha observado en países como Italia, Perú, Tanzania, Bolivia y México (Amri y Kisangau, 2012;Quiroga et al, 2012;Monigatti et al, 2013;Vitalini et al, 2013;Loredo-Medina et al 2002;MolinaMendoza et al, 2012); por tanto, es importante conocer, conservar y disponer de las especies usadas para ese fi n, en tanto que las enfermedades gastrointestinales causadas por bacterias, virus o parásitos representan 2.2 millones de muertes cada año a nivel mundial (OMS, 2011).…”

Resumen: Este estudio se realizó en Cantarranas, Huehuetla, Hidalgo, México, donde el tipo de vegetación dominante es bosque tropical perennifolio. Cantarranas presenta alto grado de marginación, limitado acceso a servicios de salud y pocas oportunidades para incrementar sus ingresos económicos. El objetivo fue planear el aprovechamiento sostenible y conservación de plantas medicinales usadas en la comunidad como una alternativa para resolver problemas ambientales y sociales. Las especies fueron evaluadas con métodos etnobotánicos y ecológicos. Se usaron entrevistas estructuradas para documentar el valor cultural de las especies, nivel de fi delidad, prácticas e intensidad de manejo, usos y padecimientos tratados. La distribución y abundancia se obtuvo con el método de transectos lineales. Las 19 especies evaluadas son usadas para atender 51 padecimientos, los desórdenes gastrointestinales se tratan mayormente mediante las plantas medicinales. Las especies con mayor índice de valor cultural fueron Equisetum myriochaetum (0.69), Psidium guajava (0.37), Jaegeria macrocephala (0.26592) y Costus scaber (0.25496). Hamelia patens registró el mayor nivel de fi delidad (96%), seguida de E. myriochaetum (88%). Los valores de intensidad de manejo fueron más altos en C. scaber (9.2) y P. guajava (9). La densidad poblacional osciló entre 1 y 387 individuos por hectárea, según la especie y forma de vida. Mediante la vinculación sociedad y Universidad, se desarrolló e impartió un diplomado para los miembros de la comunidad, relacionado con el uso y aprovechamiento sostenible de plantas medicinales. Se constituyó una Sociedad Cooperativa con mujeres de la comunidad, ellas trabajan en la conservación y aprovechamiento sostenible de plantas medicinales. Palabras clave: etnobotánica, remedios herbolarios, Otomí-Tepehua, valor cultural, vinculación. Abstract:The present study was carried in Cantarranas, Huehuetla, Hidalgo, Mexico. The vegetation type is tropical evergreen forest. Cantarranas presents high degree of marginalization, limited access to health services, and few opportunities to increase its economic income. The aim was to design a strategy for the sustainable harvesting and conservation of medicinal plants used by the community, as an alternative to solve social and environmental problems. The species were evaluated by ethnobotanical and ecological methods. Using structured interviews, index of cultural value, index of Friedman value, practices and management intensity, and uses and conditions treated were documented. The distribution and abundance were obtained with line transects method. Nineteen plants were evaluated, they are used to treat 51 conditions; the gastrointestinal disorders were the most frequently treated with medicinal plants. The species with the higher index of cultural value were Equisetum myriochaetum (0.69), Psidium guajava (0.37), Jaegeria macrocephala (0.26) y Costus scaber (0.25). Hamelia patens recorded the highest level of fi delity (96%), followed by E. myriochaetum (88%). The values of man...

“…Moreover, these antichagasic drugs are hardly accessible for the indigenous communities in Bolivia. Consequently, people living in rural areas of Bolivia rely on traditional medicines for their primary health care (17,18). Botanical drugs contribute significantly to Bolivian folk medicine and they are harvested wild, cultivated and traded at local markets (19).…”

Globally, more than six million people are infected with Trypanosoma cruzi, the causative protozoan parasite of the vector-borne Chagas disease (CD). In Bolivia, CD is hyperendemic and a major health problem among indigenous communities. Although botanical drugs are used widely among different ethnic groups in Bolivia, studies challenging the hypothesis that effective antitrypanosomal medicinal agents were identified empirically are lacking. We conducted a cross-sectional ethnopharmacological field study in Bolivia among different ethnic groups in the Chaco, Chiquitanía and Inter-Andean valleys. We compared botanical drugs used in Bolivia in the context of CD with botanical drugs from unrelated indications from the Mediterranean De Materia Medica (DMM) compiled by Dioscorides two thousand years ago. A total of 775 ethyl acetate plant extracts with and without ethnomedical indications for CD treatment were profiled against T. cruzi epimastigote and procyclic T. brucei proliferation, parasite release from T. cruzi trypomastigote infected cells, as well as for host cell cytotoxicity in vitro. Inhibition of parasite release was monitored using a flow cytometry-based celluar assay. At 25 µg/mL, less than 5% of all extracts exhibited selective toxicity for T. cruzi. We found no evidence that ethnomedicine-inspired bioprospecting significantly increased the probability of finding selective antichagasic botanical drugs. The ethnomedical data further indicate a discrepancy between local and scientific concepts about CD among the studied ethnic groups. Intriguingly, the phylobioactive anthraquinone hotspot identified in this study matched the antichagasic activity of Senna chloroclada, the taxon with the strongest consensus for treating CD among the Izoceño-Guaraní. Selected antitrypanosomal plant extracts from DMM were subjected to HPLC-based activity profiling and targeted isolation of active compounds yielding sesquiterpene lactones, naphtoquinones and anthraquinones. Because the anthraquinone emodin selectively and potently inhibited T. cruzi in host cell infection, we performed a preliminary structure-activity relationship analysis for the 9,10-anthracenedione scaffold, exploring the impact of differential hydroxylation. This study shows that the multidimensional phylobioactivity-guided identification of antichagasic natural products enables comparative bioprospecting and is suitable to challenge ethnopharmacological hypotheses. Author summaryChagas disease (CD) is a parasitic disease caused by the protozoan Trypanosoma cruzi. In Bolivia, CD is a major health problem among indigenous communities, which frequently use traditional medicine to treat the chronic symptoms of the disease related to cardiomyopathy. However, the ethnomedical context of the use of such remedies is largely unclear and it remains unknown whether the botanical drugs have any effect on parasitemia. In a field study among different ethnic groups in the Chaco, Chiquitanía and Inter-Andean valleys the authors collected ethnobotanical and ethnopharmac...

In Tunisia, Tipuana tipu (Benth.) Kuntze is an exotic tree, which was introduced many years ago and planted as ornamental street, garden, and park tree. The present work reported, for the first time, the chemical composition and evaluates the allelopathic effect of the hydrodistilled essential oils of the different parts of this tree, viz., roots, stems, leaves, flowers, and pods gathered in the area of Sousse, a coastal region, in the East of Tunisia. In total, 86 compounds representing 89.9 - 94.9% of the whole oil composition, were identified in these oils by GC-FID and GC/MS analyses. The root essential oil was clearly distinguished for its high content in sesquiterpene hydrocarbons (β-caryophyllene, 1 (44); 24.1% and germacrene D, 2 (53); 20.0%), while those obtained from pods, leaves, stems, and flowers were dominated by non-terpene hydrocarbons. The most important ones were n-tetradecane (41, 16.3%, pod oil), 1,7-dimethylnaphthalene (43, 15.6%, leaf oil), and n-octadecane (77, 13.1%, stem oil). The leaf oil was rich in the apocarotene (E)-β-ionone (4 (54); 33.8%), and the oil obtained from flowers was characterized by hexahydrofarnesylacetone (5 (81); 19.9%) and methyl hexadecanoate (83, 10.2%). Principal component and hierarchical cluster analyses separated the five essential oils into three groups and two subgroups, each characterized by the major oil constituents. Contact tests showed that the germination of lettuce seeds was totally inhibited by the root essential oil tested at 1 mg/ml. The inhibitory effect on the shoot and root elongation varied from -1.6% to -32.4%, and from -2.5% to -64.4%, respectively.
