The objective of this study was to conduct chemical analyses of bioactive compounds found in the bark and leaves of (Aubl.) A. St. Hil. and L. Chemical screening was performed to detect the presence of secondary metabolites. Quantification of the concentrations of phenolic compounds, anthocyanins, flavonoids, and antioxidants was performed by ultraviolet spectrophotometry through recommended methodologies. Extracts of the leaves of (Aubl.) A. St. Hil. were found to have high concentrations of flobabénic tannins. Tannins, flavonoids, flavonols, flavonones, flavanonols, xanthones, steroids, and saponins were also found in bark extracts of the same species. The plant species (Aubl.) A. St. Hil. and L. showed potential for antioxidant activity and for use in the pharmacological and food industries.
本研究的目的是对 (Aubl.)A. St. Hil. 和 L. 的树皮和叶子中的生物活性化合物进行化学分析。通过化学筛选来检测次生代谢产物的存在。采用推荐的方法,通过紫外分光光度法对酚类化合物、花青素、类黄酮和抗氧化剂的浓度进行定量。(Aubl.)A. St. Hil. 的叶子提取物中发现含有高浓度的 Flobabénic 单宁。在同一物种的树皮提取物中还发现了单宁、类黄酮、黄酮醇、黄烷酮、黄烷醇、蒽酮、甾体和皂苷。植物物种 (Aubl.)A. St. Hil. 和 L. 具有抗氧化活性的潜力,可用于药理学和食品工业。
