La papa, es el producto agrícola más importante en el Perú de alto consumo en la población, los pulgones (Epitrix spp) es una de las plagas en su cultivo, cuyo control requiere el uso intensivo de plaguicidas sintéticos; sin embargo una alternativa potencial puede ser el uso de productos naturales, como los aceites esenciales reconocidos por sus propiedades insecticida. En la investigación se ha determinado las propiedades fisicoquímicas, la composición química y el efecto insecticida de los aceites esenciales de Tanacetum vulgare Linnaeus y Mentha x piperita var. Vulgaris (Ehrh.) Briq., sobre Epitrix spp, insecto depredador de la papa durante su cultivo y reportadas como biocidas de uso tradicional en el Perú.1,2 Las muestras vegetales fueron colectadas en la comunidad de Ccorao, Distrito de San Sebastián, provincia y departamento del Cusco, en el mes de abril a una altura ap...

The district of Pisac in the Cusco region, due to its climate, has vast expanses dedicated to agricultural activities, which do not have studies regarding the salinity of its agricultural soils. One issue is that the quality of their agricultural products may be due to soil salinization, where farmers have observed problems in the development of their crops. The physicochemical characteristics, salinity, RAS, and PSI of the irrigation water and agricultural soils have been evaluated during the dry and rainy periods. The soils have shown low salinity and sodium in both periods, ranging for EC from 0.419 to 2.140 dS/m, pH from 7.2 to 7.9, and PSI from 0.57 to 1.47%. Likewise, the soils have shown low fertility, low water retention, and high alkalinity. The irrigation water has shown an EC of 285 to 486 μS/cm and an SAR of 0.36 to 0.65 meq/L, being classified as C2S1, which would affect th...

Clinopodium brevicalyx grows in the southern high Andean regions of Peru and has wide popular use, however to date there is no research on its activity against Trichophyton rubrum, an anthropophilic dermatophyte fungus with an affinity for human keratin and difficult to treat, causing the most common superficial mycoses such as athlete's foot, ringworm and nail infections. The aim of this research was to determine the activity of the essential oil of Clinopodium brevicalyx against Trichophyton rubrum ATCC 28188. The essential oil was obtained by hydrodistillation, the extraction rate was 1.98 ± 0.02% (w/v), and the physicochemical characteristics were: relative density of 0.93654 g/mL, a refractive index of 1.4625, an optical rotation of 2.14°, and pH of 6.20. The chemical composition of the essential oil was determined using a gas chromatograph coupled to a mass spectrometer, identify...

Las cáscaras de los cítricos presentan una gran cantidad de aceites esenciales con muchas aplicaciones en las industrias farmacéutica, cosmética y alimentaria. En las últimas décadas en nuestro país la industria de cítricos ha alcanzado un gran despegue debido al aumento de la producción interna y el crecimiento de las exportaciones, esto sumado a que a nivel internacional han ido cambiando los hábitos alimentarios de los consumidores quienes buscan alimentos funcionales, por lo que los cítricos han ganado mucha atención. Uno de los cítricos que ha venido destacando en países como India y Nigeria es el Citrus jambhiri, que también se cultiva en nuestro país y presenta en sus cáscaras un aceite esencial muy interesante. El objetivo de la presente investigación fue realizar la extracción del aceite de la cáscara de Citrus jambhiri usando el método de destilación por a...
