摘　　要：Hydrilla verticillata （Linn. f.） Royle is a submerged plant for phytoremediation on Taihu Lake, China. The planted submerged plant should be harvested in every autumn to reduce the nutrition burden of the lake. Five compounds were firstly isolated by column chromatography and purified from the extractions of Hydrilla verticillata （Linn. f.） Royle. 1-（5＇-Hydroxy-4＇-hydroxymethyl-1＇-methyl-1H-pyrrol-2＇-yl）-henicosa-2,12,15-trien-1-one （2） and thymidine （3） were identified by EIMS, 1H NMR, laC NMR and IR spectra. Crystal loliolide （1） and sulfur-gamma （4） were identified by X-ray diffraction. Octadecanedioic acid （5） was also elucidated. Among them, compound 2 is a new natural compound, loliolide （1） and thymidine （3） are known bioactive substances. The results provided basic research data for exploring their application as medical materials.Hydrilla verticillata （Linn. f.） Royle is a submerged plant for phytoremediation on Taihu Lake, China.
