四种水生植物中无机元素和维生素C的研究

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。

Studies of Inorganic Elements and Vitaminc C in Four Hydrophytes

Objective:Inorganic elements and vitamin are important component of nutrient in water plants. In order to judge the qualities of the tour 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.
