Despite the potential applications of pineapple fibers, the systematic characterization of their polyphenolic composition has not been fully elucidated. In this study, UHPLC-MS and OPLS-DA were used to comprehensively analyze the polyphenolic profiles in pineapple leaf (PLF), stem (PSF) and root (PRF) fibers, while evaluating their bioactive properties. The investigation revealed that PRF contained significantly higher polyphenol content (9.55 mg/g) than PLF and PRF, and 83 phenolic compounds were identified, with distinct metabolic pathway distributions among different plant tissues, and the inhibitory effects of polyphenol on and were optimized in PLF. These findings provide critical insights for the development of value-added applications of pineapple by-products in functional materials and antimicrobial formulations.

尽管菠萝纤维有潜在应用，但对其多酚成分的系统表征尚未完全阐明。在本研究中，采用超高效液相色谱-质谱联用仪（UHPLC-MS）和正交偏最小二乘法判别分析（OPLS-DA）全面分析菠萝叶纤维（PLF）、茎纤维（PSF）和根纤维（PRF）中的多酚谱，同时评估它们的生物活性。研究发现，PRF的多酚含量（9.55毫克/克）显著高于PLF和PSF，共鉴定出83种酚类化合物，不同植物组织间具有不同的代谢途径分布，且PLF中多酚对（此处原文缺失相关内容）的抑制作用得到优化。这些发现为菠萝副产品在功能材料和抗菌制剂中的增值应用开发提供了关键见解。
