Abstract

Tristerix corymbosus flower is used in traditional medicine for its antioxidant and antibacterial properties, which are attributed to phenolic compounds. These compounds present different grades of associations with the plant matrix (free, esterified, and insoluble). This study aimed to determine which fraction contributes the most to total phenolic and flavonoid contents and bioactive properties. The total phenolic content was higher in the free fraction. In contrast, the esterified fraction exhibited the highest total flavonoid content and the greatest number of characterised compounds (chlorogenic, coumaric, and sinapic acids). All fractions exhibited antioxidant capacity against FRAP, DPPH, and ABTS assays. The free and esterified fractions presented antibacterial capacity against E. coli, S. typhi, and S. aureus. Chlorogenic and sinapic acids were correlated with the antibacterial capacity against E. coli and S. typhi. While coumaric acid correlated with the antibacterial capacity against S. aureus. These findings enable the exploration of potential applications for the different fractions.

昆特兰花多酚组分的植物化学筛选和生物特性。

三姐妹花因其抗氧化和抗菌特性而被用于传统医药中，这些特性归功于酚类化合物。这些化合物与植物基质的结合程度不同（游离、酯化和不溶）。本研究旨在确定哪种成分对总酚和类黄酮含量以及生物活性特性的贡献最大。游离部分的总酚含量较高。相比之下，酯化馏分的类黄酮总含量最高，表征化合物（绿原酸、香豆酸和山奈酸）的数量也最多。所有馏分在 FRAP、DPPH 和 ABTS 试验中都表现出抗氧化能力。游离和酯化馏分对大肠杆菌、伤寒杆菌和金黄色葡萄球菌具有抗菌能力。绿原酸和山奈酸与大肠杆菌和伤寒杆菌的抗菌能力相关。香豆酸与金黄色葡萄球菌的抗菌能力相关。这些发现有助于探索不同馏分的潜在用途。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
