The study aimed to analyze the chemical composition of the essential oil from leaves of Petroselinum crispum (Mill) Nyman ex A.W. Hill "perejil" and determine antibacterial activity. Essential oil was obtained treating 20 kg of fresh leaves with a distillation equipment by dragging with steam; obtaining performance of 0,02 per cent and four milliliters of oil v/p. In the qualitative analysis was analyzed its solubility in organic solvents, and chemical components were determined by gas chromatography / mass spectrometry (GC/MS), achieving the elucidation of the following compounds: 1R-α-pinene, β-pinene, β-phellandrene, p,α-dimethyl estirene, (E)-2-caren-4-ol, 1,3-benzodioxol-(2-propenil) 4-metoxy-6, 1,3-benzodioxol, 4,7-dimetoxy-5-(2-propenil)-. In vitro bacterial activity determination was made by the method of diffusion in agar, demonstrating significant activity to Staphylococcus...

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 ...

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...

The presence of secondary metabolites and of chromium element in seven medicinal plants empirically used for their hypoglycemic action by a phytochemical screening and a qualitative method and other one that is quantitative by Atomic Absorptioli. Spectroscopy for detelmining trivalent chromium has been researched. The studied species are: Phyllantus niruri L. (Chancapiedra), Geranium dielsianum Knut (Pasuchaca), GentianeIla alborosea G. (Hercampure), Otholobium pubescells (Culén), Smallantus sonchifolia (Yacón), Chloraphora tincoria (Mora) y Taraxacum officinalis W (Diente de león). It was phytochemically determined the presence of the following secondary metabolites: alkaloids, flavonoids , tannins, saponins and glycosides, by means of color and precipitation reagents. The determination of chromium element was carried out by qualitative and quantitative via. The accomplished study co...
