Interrelation between the content of secondary metabolites of species Gliricidia sepium and Tithonia diversifolia and some physicochemical properties of soil
Samples were collected from 2 forage plants (leaf stalk) of the species Gliricidia sepium and Tithonia diversifolia in different soil conditions (departments of Valle del Cauca and Cesar) and evaluated for total polyphenol content, total tannins, condensed tannins and Saponinas. The purpose was to detect the effect of the conditions of electrical conductivity on the concentration of these secondary fitobiomoléculas metabolized by the plant cell. We applied analytical techniques and instrumental AOAC (2005) to determine the presence of such fitometabolitos side. The results obtained for each variable were subjected to analysis of variance two-way, in order to determine statistical differences between areas sampled and evaluated species. Additionally, we performed a multiple correlation analysis using the Pearson coefficient, in order to detect any correlation between electrical conductivity and the content of secondary metabolites quantified in the species sampled. It was concluded that the content of total polyphenols, total tannins, condensed tannins and saponins did not show statistically significant differences between the three areas sampled, and there was high correlation between the value of the electrical conductivity of soil and content of secondary metabolites.
