Studying the phytochemical composition and bioactive potential of underexploited species is of great importance for promoting their valorization and for broadening the range of sources of bioactive compounds in the human diet. In this study, we used a simplex centroid mixture design to determine an optimal extraction solvent composition (using mixtures of water, acetone, and ethanol) for maximizing the extraction of phenolic compounds and the antioxidant capacity of bacaba juice (Oenocarpus bacaba). The compounds were identified and quantified by high-performance liquid chromatography coupled with mass spectrometry. Taxifolin, orientin, and isoorientin were identified and quantified in bacaba juice for the first time. It was possible to evidence the high potentiality of the bacaba regarding the contents of syringic, vanillic, ferulic, 3,4-dihydroxybenzoic acids, and orientin, which have significantly contributed to the antioxidant capacity of the extracts. Thus, this study indicates that bacaba juice can provide antioxidant compounds. Moreover, the determined extraction conditions can be applied for obtaining extracts rich in potential bioactive properties for food and pharmaceutical applications.

研究未充分利用物种的植物化学组成和生物活性潜力对于促进其增值和扩大人类饮食中生物活性化合物的来源范围具有重要意义。在这项研究中，我们使用了单纯形质心混合物设计来确定最佳的萃取溶剂成分（使用水，丙酮和乙醇的混合物），以最大程度地萃取酚类化合物和bacaba汁（Oenocarpus bacaba）的抗氧化能力。）。通过高效液相色谱结合质谱对化合物进行鉴定和定量。首次在bacaba汁液中鉴定并定量了紫杉叶素，orientin和isoorientin。关于丁香酸，香草酸，阿魏酸，3,4-二羟基苯甲酸和Orientin的含量，bacaba具有很高的潜力，这对提取物的抗氧化能力有重要贡献。因此，这项研究表明bacaba汁可以提供抗氧化剂化合物。此外，确定的提取条件可以用于获得富含潜在生物活性的提取物，用于食品和药物应用。
