Abstract

This paper is a review that shows the impact that the use of medicinal plants has on human health. Since antiquity by tradition the majority use of some plant families was extended as the Lamiaceae that stands out for its aromatic properties and culinary application in many cultures, as well as in the treatment and prevention of a wide variety of diseases and ailments. Among the species belonging to this family is rosemary (Rosmarinus officinalis) a plant that has gained importance in the field of research for its biological attributes such as: anti-inflammatory, antimicrobial, antioxidant and anticancer, among others; results due to its secondary metabolites such as: carnosic acid, carnosol, rosmaric acid and camphor, among others, with a potential effect when applied. Some methodologies that seek the extraction of biologically active components of rosemary are also mentioned., El presente trabajo, es una revisión que muestra el impacto que tiene el uso de las plantas medicinales en la salud humana. Desde la antigüedad, por tradición, se extendió el uso mayoritario de algunas familias vegetales como la Lamiaceae que destaca por sus propiedades aromáticas y aplicación culinaria en numerosas culturas, así como en el tratamiento y prevención de una gran variedad de enfermedades y malestares. Dentro de las especies pertenecientes a esta familia se encuentra el romero (Rosmarinus officinalis), planta que ha ganado importancia en el campo de la investigación por sus diversos atributos biológicos como: antiinflamatorio, antimicrobiano, antioxidante y anticancerígeno, entre otros; resultados que debe a sus metabolitos secundarios como: el ácido carnósico, el carnosol, el ácido rosmárico y el alcanfor, entre otros más, aunado a un potencial efecto cuando es aplicado. También se mencionan algunas metodologías que buscan la extracción de los componentes biológicamente activos del romero.

Abstract

Automotive and industrial design companies have profusely used commodity materials like glass fiber-reinforced polypropylene. These materials show advantageous ratios between cost and mechanical properties, but poor environmental yields. Natural fibers have been tested as replacements of glass fibers, obtaining noticeable tensile strengths, but being unable to reach the strength of glass fiber-reinforced composites. In this paper, polyamide 6 is proposed as a matrix for cellulosic fiber-based composites. A variety of fibers were tensile tested, in order to evaluate the creation of a strong interphase. The results show that, with a bleached hardwood fiber-reinforced polyamide 6 composite, it is possible to obtain tensile strengths higher than glass-fiber-reinforced polyolefin. The obtained composites show the existence of a strong interphase, allowing us to take advantage of the strengthening capabilities of such cellulosic reinforcements. These materials show advantageous mechanical properties, while being recyclable and partially renewable., Peer Reviewed, Postprint (published version)
