不同生境下喜旱莲子草营养器官中抗氧化物质含量的比较

Comparision of contents of anti-oxidant compounds of Alternanther philoxeroider in aquatic and terrestrial environments

以水陆两种生境下生长的喜旱莲子草为实验材料 ,分别测定并比较了根、茎、叶可溶性蛋白及SOD、POD、Vc、GSH及绿原酸和类黄酮等抗氧化物质活性和含量 ,结果表明可溶性蛋白在叶中含量最高 ,并且水生环境中叶的含量高于陆生环境。除Vc外生态环境对各抗氧化物质含量影响具有一致性。水生环境下喜旱莲子草营养器官的抗氧化物质含量高于陆生环境下喜旱莲子草相应营养器官的含量。

Contents of soluble protein,SOD,POD,Vc,GSH,flavonoid and chlorogenic acid etc,from different organs of Alternanther philoxeroider in aquatic and terrestrial environments were assayed. Rusults showed that soluble protein content from leaves was the highest,especially from the plant in aquatic environment. Effects of environment on the contents of different anti oxidant compounds were the same except for that of Vc,and contents of different anti oxidant compounds from organs in aquatic environment were higher than that from corresponding organs in terrestrial environment.
