RESUMO
INTRODUCTION: Experiments have demonstrated that the association between inulin and oligofructose can prevent colitis by modifying the intestinal microflora by acting as a prebiotic. It has also been found that this association is naturally present in the roots of the Yacón root (Smallanthus sonchifolius) making phytochemical and standardization studies well worth pursuing. These studies could contribute to the safe use of improved strains of Yacón, to significant savings in health resources, and to promoting additional clinical and pre-clinical research. So far, studies have been made on organically cultivated Yacón in the coast, on varieties adapted from those cultivated in the Andes. The aim is to promote consumption of Yacón in the sectors of society that need it most. OBJECTIVE: To determine the general chemical composition of the Yacón tuberous root cultivated in the coast by means of a phytochemical screening, as well as standardizing its inulin content in order to contribute knowledge on its conditions of use. METHODS: The roots harvested in the Lima Botanical Garden of the National Health Institute were used to prepare aqueous extracts through decoction and juice for the phytochemical screening with conventional reagents. The aqueous extracts were standardized for insulin content by using a fructose standard method and a validated analytical technique. The samples were read in a TU-1810S Split Beam UV-VIS spectrophotometer. RESULTS: The trials confirmed the presence of phenolic compounds, flavonoids, alkaloids, steroids, glycosides and carbohydrates. The standardization found values of 7,8% inulin in the hydrolyzed extract and of 7, 01% in the non-hydrolyzed extract. CONCLUSIONS: The extracts of the Yacón roots were screened and standardized Ander known cultivation conditions. The possibilities of its use are being considered due to its prebiotic properties. These properties are considered useful in treating certain types of colitis by stimulating the growth of the Lactobacillus and Bifidobacterium microflora. Saving of health resources would be possible and further clinical and pre-clinical research would be encouraged.

Introducción: Se ha demostrado experimentalmente que la asociación inulina más oligofructosa puede prevenir la colitis al modificar la microflora, actuando como un prebiótico. También se ha encontrado que tal asociación de inulina más oligofructuosa se encuentra en las raíces de Yacón (Smallanthus sonchifolius). Ello, amerita su estudio fotoquímico como su estandarización, con el fin de contribuir a su consumo con seguridad y calidad, a los ahorros en recursos de salud y promover adicionales trabajos preclínicos y clínicos. El estudio se realizó sobre la especie cultivada orgánicamente en la Costa, adaptada de la que crece en los Andes, para propiciar su consumo económico en sectores de la sociedad que lo requieran. Objetivos: Determinar la composición química general de las raíces tuberosas de Yacón cultivado en la Costa, mediante tamizaje fotoquímico. Además, la estandarización de su contenido de inulina para contribuir al conocimiento de las condiciones en su empleo. Métodos: Con las raíces cosechadas en el Jardín Botánico del Instituto Nacional de Salud en Lima, se prepararon extractos acuosos por decocción y zumo para el tamizaje fotoquímico con reactivos convencionales. Se estandarizaron los extractos acuosos por su contenido de inulina, empleando un estándar de fructuosa y técnica analítica validada. Las muestras fueron leídas en un Espectrofotómetro UV-VIS, Modelo TU-1810S Split Beam. Resultados: Los ensayos confirmaron la presencia de compuestos fenólicos, flanovoides, alcaloides, esteroides, glicósidos y carbohidratos. La estandarización encontró valores de 7.8 por ciento de inulina en el extracto hidrolizado y de 7.01 por ciento en el sin hidrolizar. Conclusiones: Se tamizaron y...
