This study aimed to characterize the chemical components of essential oil of Citrus sinensis L., determine its antibacterial activity and make dosageforms, mainly for local use. The essential oil was obtained from the dried leaves of the selected species, using a hydrodistillation system with water steam sweep; tests were conducted miscibility and determination of physical constants, such as specific gravity, refractive index and optical rotation. The chemical composition was determined by Gas Chromatography/Mass Spectrometry (CG/EM), standing out in the sugiero: chromatogram spectral signals in the elucidating: Limonene, beta-linalool, decanal and 2 (10)-pinene(1S,5S)-(-)-. The determination of antibacterial activity in vitro was tested by agar diffusion method and the formation of inhibition halos against strains of Gram (+), as Staphylococcus aureus ATCC 25,933 and Staphylococcus epid...

Objective of the study was to compare the sunscreen effect in vivo of a cream made with the hydroalcoholic extract of the brown seaweed Macrocystis pyrifera (Linnapus) Agardh, with comercial sunscreens in skin lesions prevention. The biological sample was collected in the continental socket from Yanyarina beach, San Juan de Marcona, Ica region. Hydroalcoholic extract (ethanol 1:1) was obtained for maceration process since 300 g seaweed. With the extract was formulated and design the blocker dermocosmetic using concentrations of 5, 10, and 15%, respectively, with a mixture of solids aliphatic alcohols, consisting mainly of Cetyl alcohol (C16H3O) and Stearyl alcohol (C18H39O) 50/70%. Were used albino mice, mus musculus specie, bald c53 strain, adult males, with average weight 30 g. Photoprotective potential in vivo was tested through topical application on mice skin, in the dorsal anterior...

El estudio tuvo como objetivo comparar el efecto fotoprotector in vivo de una crema elaborada con el extracto hidroalcohólico de la macroalga parda Macrocystis pyrifera (Linnapus) Agardh frente a bloqueadores solares comerciales en la prevención de lesiones de piel. La muestra biológica fue colectada en el zócalo continental de la playa Yanyarina de San Juan de Marcona de la región Ica. El extracto hidroalcohólico (etanol-agua 1:1) se obtuvo por proceso de maceración a partir de 300 g de alga. Con el extracto se formuló y diseño el bloqueador dermocosmético empleando concentraciones 5, 10 y 15%, respectivamente, con una mezcla de alcoholes alifáticos sólidos, conformados principalmente por alcohol cetílico (C16H3O) y alcohol estearílico (C18H39O) 50/70%. Se emplearon 35 ratones albinos adultos machos de la especie Mus musculus cepa Bald C53 de peso promedio 30g. El potencia...
