Abstract: Objective:Inorganic elements and vitamin are important component of nutrient in water plants.In order to judge the qualities of the four hydrophytes including taro, water chestnut,wild rice stem and water caltrop.Method:The flame atomic absorption spectrometry and titration with the 2,6-Dichloroindophenol sodium were applied to determine the content of the inorganic elements and the vitamins in them.Results:The determination results indicated that the content of the nutrients from the four water plants was higher than other common vegetable.Conclusion:It is a wide prospect that water plants could be exploited comprehensively.
