欧亚水藻（Myriophyllum spicatum）茎部丙酮水提物对多种球藻和丝状蓝藻具有较强的抑制作用，对绿藻和硅藻的抑制作用略弱。生物测定定向分离分离了一种可水解的多酚，tellimagrandin II，这被证明是主要的抑制物质。狐尾豆科植物含有大量的这种化合物（占干重量的1.5%）。部分抑制活性是由于藻胞外酶（如碱性磷酸酶）的络合和失活的水解多酚从spicatum。
Aqueous acetone extracts of shoots of Eurasian watermilfoil (Myriophyllum spicatum) exhibit a strong inhibitory action against various coccoid and filamentous cyanobacteria and to a slightly less extent against chlorophytes and diatoms. Bioassay-directed fractionation led to the isolation of a hydrolysable polyphenol, tellimagrandin II, which turned out to be the main inhibitory substance. Myriophyllum spicatum contains large amounts of this compound (1.5 % of dry wt). Part of the inhibitory activity is due to complexation and inactivation of algal extracellular enzymes (e.g. alkaline phosphatase) by hydrolysable polyphenols from M. spicatum.
