Evaluación de paramétros fisicoquímicos durante el crecimiento, desarrollo y poscosecha de las especies Vasconcellea pubescens, Solanum quitoense var. Septentrionale y Capsicum Pubescens Ruiz & Pav, cuantificación de polifenoles totales y análisis cualitativo de metabolitos secundarios presentes en estas y otras especies priorizadas en el proyecto “biodiversidad altoandina al plato de todos"

Abstract

The Botanical Garden of Bogotá has been developing, in recent years, the project "High andean biodiversity to the plate of all", with which it is intended to solve the problem of ignorance and disuse of the nutritional and nutraceutical properties present in some native plant species ; causing, thus, an evident diminution of its populations and consequent loss of the ecosystemic equilibrium. In order to define one of the phases of the project, the objective of evaluating physicochemical parameters during the growth, development and postharvest of the fruits of the species Vasconcellea pubescens, Solanum quitoense var. septentrionale and Capsicum pubescens Ruiz & Pav, quantify the total polyphenols and qualitatively analyze the presence of secondary metabolites present in these and other prioritized species in the project of "High Andean Biodiversity to the plate of all". For the above, an analysis of growth of the fruits of the mentioned species was carried out, in different degrees of maturity; an evaluation of physicochemical parameters, such as firmness, SST, pH, and titratable acidity, in fruits under post-harvest conditions and in growth and development; Likewise, the total polyphenols were quantified by the Folin-Ciocalteu method and the presence of secondary metabolites, present in these and other species, was analyzed qualitatively by phytochemical screening. It was found that during the stage of growth and development, the dimensions of the fruits increased proportionally; For the physicochemical parameters, values ​​similar to those reported in the literature were obtained, both for the fruits in growth and development and in postharvest. Likewise, a significant content of total polyphenols was quantified and the presence of secondary metabolites, with nutraceutical properties, was identified in all species.
