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 aim of this study was to determine the antibacterial activity of essential oil Minthostachys mollis “ruyaq muña”, against Helicobacter pylori, Shigella dysenteriae, Salmonella typhi and Pseudomonas aeruginosa. The leaves of M. mollis were collected in the district of Huamanguilla (3000-3200 m.s.n.m), Huanta province, Ayacucho region. The essential oil obtained by distillation with water vapor drag. The antibacterial activity was determined by plate cultive excavation method, resulting in order of sensitivity, for S. dysenteriae 21.41 mm; H. pylori 17,07 mm; S. typhi 14.25 mm and P. aeruginosa 11.45 mm. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for H. pylori were determined by the microplate dilution method, resulting in 2 μg/mL. For the other bacteria was determined by the dilution method, being for S. dysenteriae 4 μg/ml, S. typhi...

The aim of this study was to determine the applicability of near infrared spectroscopy (NIRS) for the nutritional assessment of two important forage species in the country: alfalfa (Medicago sativa L) and red clover (Trifolium pratense L). For this, 75 samples of alfalfa varieties (SW 8210, WL 625HQ) and 75 of red clover varieties (Quiñequeli, Kendland) obtained from the paddocks of the IVITA El Mantaro Experimental Station, Junín region, Peru were used. Proximal analysis was performed determining the content of crude protein (CP), ether extract (EE), crude fibre (CF), total ash (TA) and neutral detergent fibre (NDF), and the spectrum was captured using NIRS equipment. The calibration and validation models were developed to estimate the predictive capacity using Partial Least Squares (PLS), and the accuracy and precision statistics used were the Correlation Coefficient (R), Determinati...
