摘　　要：目的：水生植物中的无机元素和维生素是水生植物营养成分的组成部分，为了评价四种水生植物（芋头、荸荠、茭白、菱角）的品质。方法：用火焰原子吸收法和2,6-二氯酚靛酚滴定法[1]对它们中的无机元素和维生素C进行测定。结果表明：四种水生植物中各种营养素的含量均很高。结论：水生植物综合开发和使用前景广阔。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.
