| dc.description | In the last decade, with the continuous advance of science, has been possible to demostrate several beneficial effects of the different phenolic compounds on human health as potential antioxidants, control of metabolic processes, etc. The continuous consumption of antioxidant compounds is related to the prevention of chronic noncommunicable diseases such as cancer, diabetes, chronic respiratory and cardiovascular diseases, since that as their development is associated with oxidative stress. For this reason, it has been searched natural products that are normally consumed in the diet and have antioxidant capacity, such as fruits, legumes, tubers, among others. Ecuador is known for being a country with a great diversity of flora and fauna, which has led to the development of different types of juices and drinks based on vegetable products. This habit can bring benefits for the prevention of diseases that are related to the age and lifestyle of people. For this reason, the general objective of this study was to determine the phenolic profile of the main fruits, grains and tubers consumed in the highlands of Ecuador. For which an extraction was carried out with an organic solvent, such as methanol (80 percent). For the characterization of phenolic acids, the high resolution liquid chromatography (HPLC) technique was used with a mobile phase composed of formic acid (0.1 percent) and pure acetonitrile. From this analysis it was obtained that the fruits are the vegetal products with greater variety and content of phenolic acids. The babaco, cocoa and tree tomatoe were the fruits with more variety and the vanilla the one of greater quantity of total phenolic acids (486,45 more less 133,28 mg/100g de PS). However, the white bean and the goose belonging to the groups of grains and tubers respectively, also have a high concentration of total phenolic acids. In conclusion, it is recommended to perform a more extensive analysis, with a greater number of standards and homogeneous samples, with respect to its origin and stage of maturation. | en |
