El presente trabajo de investigación intitulado “Determinación del contenido de compuestos fenólicos y evaluación de la actividad antioxidante de Myrcianthes myrsinoides (H.B.K.) Grifo, procedente del Distrito de Cachicadán – La Libertad, Perú”, tiene por objetivo determinar la correlación del contenido de compuestos fenólicos y la actividad antioxidante de cinco extractos de Myrcianthes myrsinoides. La especie se identificó en el Herbarium Truxillensis (HUT), en donde se le asignó el código 5782; se prepararon tres extractos hidroalcohólicos (etanol de 96°, 70° y 45° G.L.) y dos extractos acuosos (infuso y decocto) al 10% P/V. Los compuestos fenólicos se cuantificaron por el método de Folin-Ciocalteu, cuyos valores fluctuaron entre 25,29 ± 0,01 mg/g para el extracto etanólico de 96° G.L. y de 73,80 ± 0,01 mg/g para el decocto. Así mismo, se evaluó la activid...

The purpose of this report is to evaluate the antibacterial activity of five plant species from the district of Cachicadán, province of Santiago de Chuco, La Libertad region. The plant species used were Cuphea ciliata Ruiz & Pav., Myrcianthes myrsinoides (Kunth) Grifo, Clinopodium pulchellum (Kunth) Govaerts, Desmodium molliculum (Kunth) DC. and Bejaria aestuans Mutis ex L .; the strains used were Bacillus subtilis, Escherichia coli, Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA). The extracts were prepared at 10% in ethanol of 45 ° G.L. The antibacterial activity was evaluated by the ratio of the minimum inhibitory concentration and the minimum bactericidal concentration (CMB/MIC). The determination of CMI was carried out by the method of microdilution in Mueller-Hinton medium and the determination of CMB by the agar diffusion method. The results of MIC o...

The purpouse of this work is to determine physicochemical characteristics of the dried leaves of Piper aduncum from the province of San Marcos – Departament Cajamarca. The dried leaves of Piper aduncum were collected in August 2013, I was selected dried and ground stored at the temperature of 40° Celsius and then sieved using N° 17 sieve. Sample were in ambar bottles for posterior use. It was determined in the dried leaves of Piper aduncum, ashes: 11,35 % ± 0.54 total ashes, 6,24% ± 1,54 soluble water ashes and 4,95% ± 0.04 insoluble in hydrochloric acid ashes
