Induced water hyacinth with purple roots (PRWH) exerts a significant inhibitory effect on the growth of blue-green algae. Interestingly, its chemical constituents differ from those of wild-type water hyacinth and have not yet been reported. This study aimed to explore the chemical constituents of PRWH and its bioactive components serving as allelopathic agents against blue-green algae. Phytochemical investigation of the bioactive ethyl acetate fraction of a crude methanol extract from PRWH led to the isolation of 56 compounds, including 11 new phenylphenalene derivatives. The structures of these compounds were elucidated by comprehensive analyses through NMR, HRMS, and X-ray techniques. Bioactivity evaluation against indicated that compounds , , , , , , and potently inhibited blue-green algae growth.
诱导产生的紫根水葫芦（PRWH）对蓝绿藻的生长有显著的抑制作用。有趣的是，其化学成分与野生水葫芦不同，尚未有报道。本研究旨在探索 PRWH 的化学成分及其生物活性成分作为化感物质对蓝绿藻的抑制作用。通过对 PRWH 甲醇粗提物的生物活性乙酸乙酯部分进行的植物化学研究，共分离得到 56 种化合物，包括 11 种新的苯并菲衍生物。通过 NMR、HRMS 和 X 射线技术的综合分析，阐明了这些化合物的结构。对化合物的生物活性评价表明，化合物 、 、 、 、 、 和 对蓝绿藻的生长有很强的抑制作用。
