This study aimed to assess the biochemical responses of Parkia gigantocarpa saplings to waterlogging. Waterlogging was imposed by flooding the saplings in 14 kg pots to approximately 5 cm above the soil surface. The experimental design was completely randomized and involved two water conditions (control and waterlogging) over five assessment periods (after 0, 4, 8, 12 and 16 days of waterlogging), with five replications per treatment. Starch, sucrose, total soluble carbohydrates and total soluble proteins were measured. The saplings exposed to waterlogging showed significant reductions in starch concentrations (62.50%) and total soluble proteins (40.98%), especially in the leaves. Waterlogging reduced the concentration of sucrose in leaves (44.38%) and increased it in the roots (76.78%). The total soluble zarbohydrate concentration increased by 106.9% in the roots of plants exposed to waterlogging. This study showed the susceptibility of Parkia gigantocarpa saplings to waterlogging. |

Quantification of bioactive phenols, like stilbenes and flavonols (SaF), has been conducted to evaluate the nutraceutical potential of red wines. However, there is still a lack of full validated, fast and accessible liquid chromatography methods offering high selectivity and a simple procedure. We present here the use of a high-resolution mass spectrometer to evaluate the selectivity of a feasible and traditional liquid chromatography technique (HPLC? DAD) to analyze markers of aglycone SaF in red wines. The SaF compounds were tested: trans-resveratrol, trans-eviniferin, quercetin, myricetin, and kaempferol, as well as trans-cinnamic acid, one of their precursors. System suitability and validation tests were employed for the selected conditions (octylsilane column, methanol mobile phase, and gradient elution). The validation process ensured the HPLC?DAD method was selective, linear, sensitive, precise, accurate and robust. The method was then applied to red wine samples from the Campanha Gau´cha region, Southern Brazil. The real samples contained different SaF levels, showing that the method is applicable to routine use. Furthermore, this was the first SaF characterization of red wines from the Campanha Gau´cha, contributing to regional and product development.
