The objective of the study was to elucidate the structure of the etanólic extract of the stem of Brunfelsia grandiflora D. Don and to evaluate its citotoxicity and the neuropathological effect on rat cerebellum. Obtained the extract the structural elucidation was made by Gas Chromatography/was made /Espectrometría of Masa (CG/EM), identifying the chemical components: Etil ester of vainíllic, octacosano, octadecan acid, palmític acid, 7 hidroxi-6-metoxi-cumarin, linoleate of ethyl and linoleic acid. The cytotoxic analysis was evaluated in embryos of Tetrapygus Niger black sea urchin, applying different concentrations of the extract. The evaluation of the neuropatológic effect of the etanólic extract in the rat cerebellum was made in 30 albino rats, Holtzmann strain, male stock, with corporal weight average of 250g approximately. For the study of the neuropatológic effect were admin...

Study objective was performing the structural elucidation of the essential oil of Ruta graveolens L. Ruda, determine its antioxidant activity and cytotoxicity testing. The complete plants were collected in Tarma, Region of Junin, and provided 1,80 kg of fresh leaves that were treated in a drag system with water vapor, obtaining performance of 0,3% v/p essential oil perfusion. The structural elucidation of chemical constituents of essential oil was performed by Gas Chromatography – Mass Spectrometry (GC-MS), stressing the identification of the following chemical components: 2-octanona 2-nonanona, nonanal, ciclohexen-5, 6-dietenil-1-methyl-, 2-decanona, nonyl ether, methyl 2-undecanona, ciclotetradecano, 2-dodecanona and 2-tridecanona. Evaluation of antioxidant activity in vitro of essential oil was made with the radical 2, 2-difenilpicrilhidrazil (DPPH) uptake method, demonstrating the ...

It was carried out the comparative evaluation of three synthetic drugs used as oral hypoglycemiants, against the aqueous obtained by infusion of leaves from Smallantus sonchifolius (Poepp) Rob. Yacon , using a experimental biomodel by hypoglycemia in normoglycemic rats of species Rattus norvegicus Var. Albine. The object of the research was to observe the 10 % aqueous extract effect of Smallantus sonchifolius (Poepp) Rob. Yacon in the decay of glycemia against glibenclamide, c1orprofamide and metformine drugs that have great usage in the treatment of type 2 diabetes mellitus (DM2). The vegetal material was collected in the Huancabamba district, province of Oxapampa in Cerro de Pasco department. The pharmaeological assay was taken with 36 female albine rats of Holtzman strain , with a average weight of 240g that were fed by a controlled foad and water ad libitum until the moment of experi...

Se realizó 1a evaluación comparativa de tres fármacos de síntesis utilizados como hipoglicemiantes orales con el extracto acuoso obtenido por infusión de las hojas de Smallanthus sochifolíuS (Poepp) Rob. "yacón", utilizando un biomodelo experimental por hiperglicemia en ratas normoglucémicas de la especie Rattus norvegicus var. Albina. El objetivo de la investigación fue observar el efecto del extracto acuoso al 10% de las hojas de "yacón" en el descenso de la glicemia frente a la glibenclamida, clorpropamida y metformina, que tienen amplio uso en el tratamiento de la diabetes mellitus tipo 2 (DM2). El material vegetal fue colectado en el distrito de Huancabamba provincia de Oxapampa del departamento de Cerro de Pasco. El ensayo farmacológico se realizó con 36 ratas albinas hembras, cepa Holtzman con un peso promedio de 240 g, que estuvieron sometidas a una alimentación cont...

The present research was aimed to determine qualitatively the chemical constituents and antibacterial, antifungal and antioxidant activity of essential oil from leaves of Tagetes elliptica Smith “chincho”, native of the province of Huaraz, Ancash region, which was obtained by the method of distillation with water vapor. Later physicochemical constants were determined, and then made the determination of chemical composition by Gas Chromatography / Mass Spectrometry (GC/MS). By the methods of agar diffusion and agar dilution were determined antimicrobial activities and minimum inhibitory concentration (MIC), respectively, against the following microorganisms: S. aureus ATCC 25933, S. epidermidis (clinical isolate), B. subtilis (environmental strain), E. coli (clinical isolate), P. aeruginosa ATCC 27853, Klebsiella (clinical isolate) and C. albicans ATCC 10231. In tests, the essential o...
