| Abstract: |
| Water eutrophication could lead to the changes of Cyperus papyrus nutritional status and the secondary metabolites content. C. papyrus were sampled from upper to lower reaches of a ditch located in Kunming botanic garden, the water in the ditch were polluted by domestic sewage with different eutrophication levels, and the effects of water eutrophication on the biomass and chemical constituents of underground part of Cyperus papyrus were investigated with HPLC analysis. The results showed that the biomass of underground part of C. papyrus were significantly declined with the reduction of water eutrophication. The biomass of underground part of C. papyrus were 1.74 ~ 3.18 kg·m-2, which is equal to or higher than that in its origin. The content of nitrogen and phosphorus of underground part of C. papyrus was significantly influenced by the water eutrophication degrees. Compared with the upper reaches, the contents of nitrogen in the middle reaches and lower reaches decreased 43.5% and 38.2% respectively, and the content of phosphorus decreased 16.2% and 27.7% respectively. The chemical constituents of underground part of C. papyrus changed dramatically with the eutrophication levels. From upper reaches to lower reaches, the content of 1-sesamin（38） increased significantly, the content of cryptomeridiol（40） trended to increase, the content of loliolide（18） decreased significantly, the content of chrysoplenetin（35） and artemetin（37） were not affected by water eutrophication. Furthermore, the other 10 unknown compounds increased significantly with the decrease of eutrophication, and 2 compounds decreased significantly with the decrease of eutrophicatio. The contents of the remaining compounds were irregular to the water quality. |
