Oxidative stress generates several inflammatory diseases with cell death and carcinogenesis. Luma chequen (Molina) A. Gray "arrayán" is a native specie with anti-inflammatory and antimicrobial virtues and corpse (post mortem tissue) preservative .With the goal of characterizing the chemical composition and determining antioxidant activity of essential oil of L. chequen, it was carried out the present work. The essential oil reports a (1.25 % v /p) performance, (+6 a -8) optical rotation, (0.9044 g/mL) density and a (1.470) refraction index. By means of CG-SM and NMR-13C it was elucidated the structures of 40 compounds at a 93,6 % of the whole sample, monoterpenic hydrocarbons (68.8 %), containing α-pinene (57.3 %) and β-pinene (6.2 %) oxygenated hydrocarbons (18.9%), emphasizing 1,8 cineol (7.5 %), linalool (3.7 %), and trans-verbenol (2.2 %), sesquiterpenes (3.0 %), with β-selinene ...

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...

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 ...
