蓬子菜、木地肤、藜3种植物叶片粗蛋白含量的测定与比较分析

利用凯氏定氮法对茜草科拉拉藤属植物蓬子菜（Galium verum）、藜科藜属植物藜（Chenopodium album）和藜科地肤属植物木地肤（Kochia prostrata）的叶片粗蛋白含量进行了测定与比较分析。结果表明,蓬子菜、藜、木地肤3种植物叶片粗蛋白含量依次为0.58%、1.06%和0.40%,其中,藜的叶片粗蛋白含量较其他2种植物叶片粗蛋白含量高,木地肤与藜的种间表现为差异显著（P〈0.05）,而蓬子菜与木地肤的种间表现为差异不显著（P〉0.05）,蓬子菜与藜的种间表现为差异不显著（P〉0.05）。

Determination and Comparison Analysis of Leaf Crude Protein Content of Galium verum,Kochia prostrate,Chenopodium album

In this study, Kjeldahl method was used to determine the leaf crude protein content of Galium verum, Kochia prostrate and Chenopodium album. The results showed that the leaf crude protein content of Galium verum, Chenopodium album and Kochia prostrate were 0.58%, 1.06% and 0.40%, respectively. The crude protein content of Chenopodium album leaves was higher than that of Galium verum and Kochia prostrate leaves. While significant differences were found between the leaf crude protein content of Chenopodium album and Kochia prostrate（P〈0.05）, none of that were observed between Galium verum and Kochia prostrate and between Galium verum and Chenopodium album（P 〉0.05）.
