Hydrilla verticillata(L. f.) Royle is a perennial submerged macrophyte.It plays an important role in the phytoremediation of eutrophic lake.In order to develop effective approach for the utilization of submerged macrophyte,the chemical composition of Hydrilla verticillata(L. f.) Royle was analyzed with sequential solvent extraction and separation on silica gel column.Two compounds were first isolated from the ethyl acetate extract of the plant.They were identified as 6-hydroxy-stigmast-4-en-3-one and octadecanoic acid on the basis of spectroscopic analyses with IR,MS,¹H NMR and ¹³C NMR.6-hydroxy-stigmast-4-en-3-one belongs to the family of steroids in which most of the members found in plants have biological activities.The biological activities of 6-hydroxy-stigmast-4-en-3-one have not been found in literatures.Further work on its biological activity test needs to be carried out.Octadecanoic acid and its derivatives can ben used as pharmaceutical material for moisturizing the intestine and inducing lax.The results have provided a new approach for the utility of Hydrilla verticillata(L. f.) Royle.
