It was obtained the essential oil from fresh and dehydrated leaves of plant specie Rosmarinus officinalis L. "romero" from Huaraz (Ancash), Huancayo and Lima, with the purpose of determining if the species cultivated, harvested in the time of flowering and post flowering, meets the international standards such as herb flavor. Dehydration was carried out in air circulating oven at 38°C for 48 hours. For the proximal analysis were used methods of OMA of AOAC international (2011). The essential oil was carried out by extraction method of volatile oils draggable by vapor stream. The results obtained in fresh and dehydrated sample in g% were, respectively, humidity (gravimetric method) 62,41 and 18,82; (azeotropic method) 60,50 and 16,20; total ash 2,34 and 5,44; acid insoluble ash 0,16 and 0,15; proteins 4,68 and 5,32; carbohydrates 20,61 and 45,05; fiber 4,52 and 14,62; fat 7,35 and 13,37;...

Se obtuvo el aceite esencial de hojas frescas y deshidratadas de la especie vegetal Rosmarinus officinalis L. “romero”, procedente de Huaraz (Ancash), Huancayo y Lima, con la finalidad de determinar si la especie cultivada, recolectada en la época de floración y post floración, satisface los estándares internacionales como hierba de sabor. La deshidratación se realizó en estufa de aire circulante a 38°C por 48 horas. Se hizo el análisis proximal empleándose los métodos de OMA de la AOAC International (2011). La obtención del aceite esencial se realizó por el método de extracción de aceites volátiles arrastrables por corriente de vapor. Los resultados obtenidos en la muestra fresca y deshidratada en g% fueron, respectivamente, humedad (método gravimétrico) 62,41 y 18,82; (método azeotrópico) 60,50 y 16,20; cenizas totales 2,34 y 5,44; cenizas insolubles en ácido 0,...

In this study, was investigated the antistaphylococcal activity in vitro of ethanol and hydroalcoholic extracts of 3 peruvian medicinal plants: Juglans neotropica Diels (bark), Piper lineatum Ruiz & Pav. (leaves) and Terminalia catappa L. (leaves). The species were collected in the regions of Amazonas and Cajamarca, in Peru. Antistaphylococcal activity was assessed by microdilution method. The organisms used were bacteria Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis ATCC 12228. All extracts investigated showed significant activity against both bacteria with a minimum inhibitory concentration (MIC) of 125 to 500 μg/mL for Staphylococcus aureus, with increased activity of the ethanol extract of Juglans neotropica Diels, and of 250 to 500 μg/mL for Staphylococcus epidermidis, having greater activity the hydroalcoholic extract of Piper lineatum Ruiz & Pav.
