ABSTRACT
A good deal of research has been carried out on the establishment and characterization of antioxidants and antibacterialproducts from natural sources for topical use. Recently, investors mainly from the cosmetics industry have becomeinterested in products from different species, not only for their individual active principles but also in the crudeextract itself. Propolis is one of such products. Several previous reports have demonstrated the antimicrobial, antiinflammatory, and wound healing effects of propolis. Additionally, what has drawn attention of the pharmaceuticalindustry to propolis and its derivatives, such as throat spray, is related to its antioxidant properties, having the potentialfor treatment and prevention of oxidative stress-mediated diseases, such as those developed on the skin, as well asaging. This literature review will focus on propolis composition and related potential uses in topical pharmaceuticaland cosmetic formulations.
ABSTRACT
Se realizó el estudio fitoquímico de Tridax procumbens L. (romerillo), en laboratorio provincial de control y calidad de la provincia de Holguín, se realizó la maceración del follaje de la planta con solventes de polaridad creciente por 24 horas en frascos de vidrio; para determinar los metabolitos secundarios de la planta. Las características macromorfológicas se correspondieron con las que se reportan para esta especie. Se logró determinar la presencia de metabolitos secundarios de esta planta siendo recolectada en estación de verano. El tamizaje fitoquímico evidenció la presencia de esteroides, flavonoides, aminoácidos y azúcares reductores. A esta especie medicinal se le reporta un gran número de propiedades terapéuticas que se corresponden con los metabolitos encontrados.
A phytochemical study of Tridax procumbens L. (romerillo) was carried out at provincial laboratory of control and quality of Holguín province, to determine the presence of secondary metabolites this plant by maceration of the foliage, being recollected in summer season with solvents of increasing polarity 24 hours in glass flasks. Macromorphological characteristics corresponded with those reported for this species. The phytochemical study evidenced the presence of steroids, flavonoides, amino acids and reducing sugars. To this medicinal sort has been attached a large number of therapeutic properties that correspond with metabolites found.
ABSTRACT
Introducción: las plantas medicinales son todas aquellas que contienen un principio activo o más, los cuales, administrados con la dosis adecuada, producen un efecto curativo a las enfermedades del hombre y los animales. El hecho de contener más de un principio activo hace que una planta medicinal pueda servir para tratar diferentes afecciones o trastornos. Objetivo: analizar los beneficios y las potencialidades terapéuticas de la planta marina Thalassia testudinum a partir de una revisión de la información existente y los principales resultados de las investigaciones realizadas sobre este organismo marino. Desarrollo: los productos naturales con propiedades terapéuticas han sido muy utilizados en la medicina tradicional. Indudablemente, los extractos de plantas de origen terrestre han representado hasta el presente una de las fuentes de mayor interés para la obtención de fitofármacos. Sin embargo, una fuente útil aún no explorada lo suficiente son los organismos marinos, que al evolucionar y vivir en condiciones ecológicas únicas y como resultado de su gran diversidad taxonómica en relación con la de los organismos terrestres, pueden sintetizar moléculas que no tienen equivalencia con las encontradas hasta el presente en estos últimos. Eso puede derivar en la obtención de estructuras químicas novedosas con efectos farmacológicos sui generis, tal es el caso de la fenograma marina Thalassia testudinum...
Introduction: medicinal plants are those which contain one or more active principles that have a curative effect upon some illnesses which affect men and animals, whenever it is adequately administered. When one plant contains more than one active principle, it can be used to treat different ailments or body disorders. Objective: to analyze the benefits and therapeutic potentialities of the sea plant Thalassia testudinum based on the existent information and in the main results of research works about this sea organism. Development: natural products with therapeutic properties have been widely used in traditional medicine. Undoubtedly, the extracts from ground origin trees have so far represented one of the most interesting sources for phytodrugs. Nevertheless, sea organisms are a useful source which has not been fully explored. As they live and evolve in unique ecologic conditions, and as a result of their great taxonomic diversity in relation to that of ground organisms, they can synthesize molecules that are not equivalent to those of ground organisms found until now. This can derive in obtaining new chemical structures with sui generis pharmacological effects as in the case of the marine phenogram Thalassia testudinum. From this plant, poliphelonic structure-rich extract has been obtained, which show therapeutic potentialities associated to the great variety of beneficial effects that have been described in the studies such as anti-inflammatory, cytoprotective, antioxidative and neuroprotective properties. All the aforementioned turns this new developing product into a possible phytodrug. Conclusions: the sea organisms represent a new source to obtain new phytodrugs and nutritional supplements of great use in human health and nutrition
