Eugenia punicifolia (Kunth) DC. is a medicinal plant used to treat diseases related to oxidative processes. In this work, H-1 nuclear magnetic resonance (NMR) spectroscopy and multivariate analysis have been employed to track the chemical changes and antioxidant activity of dimethyl sulfoxide (DMSO) extracts from E. punicifolia leaves over seasons. Principal component analysis (PCA) applied to H-1 NMR allowed discriminating DMSO extracts from leaves collected in the dry and rainy seasons and pointed out sucrose, catechin, and epicatechin as responsible for separating dry season samples and quercetin, acid gallic, glucose, and fatty acids contributed for rainy samples grouping. Notably, antioxidant assays revealed that dry season extracts exhibited a higher radical scavenging capacity. When those compounds were submitted to partial least squares-discriminant analysis (PLS-DA) only sucrose and fatty acids presented variable importance projection (VIP) score > 1, both metabolites are related somehow to the defense mechanisms of the plant. This pilot study may suggest new experimental approaches for more effectively monitoring the spectrum-effect relationship of E. punicifolia leaf extracts. |

The objective of this work was to evaluate the efficiency of nitrogen fertilization in relation to the population of corn plants in a yellow latosol under no-tillage system. The experimental design was a randomized block with three replications, in a 4 x 4 factorial scheme, corresponding to four levels of N (0, 60, kg haˉ1 120 and 180) and four planting densities (45,000; 55,000; 65,000 and 75,000 plants haˉ1). 48 soil samples were collected to determine chemical soil attributes (pH, OM, K, Ca, Na, Mg and Al) and 48 leaf samples to determine macronutrients in the leaf (N, P, K, Na, Ca and Mg). The data were submitted to comparison of means by the Scott-Knott test. The corn yield increased linearly up to the dose of 180 kg haˉ1 N. Higher productivity was observed with the combination of 120 and 180 N (kg haˉ1) with the density of 75,000 plants ha-1. There was an increase in the N content in the leaves with increasing doses of N in the soil. |
