| 摘 要： | 为了确定一种快速准确测定浒苔藻体叶绿素含量的方法,利用分光光度计法比较了两种不同的提取方法及4种提取剂测定叶绿素的效果,并分析了叶绿素在4种提取剂中的稳定性。结果表明:两种提取方法下4种不同提取剂的吸收光谱基本相似,可以用Arnon法的计算公式来计算叶绿素含量。其中,研磨法对浒苔叶绿素的提取效果较浸提法提取速度更快,便于快速测定藻体叶绿素含量。在4种提取剂中,采用95%乙醇提取浒苔叶绿素速度更快,但提取的总量少,稳定性低。

| Abstract: | In order to rapid and accurate determine chlorophyll content of Ulva prolifera,we compared the efficiency of the chlorophyll extractives using spectrophotometer with two different techniques and four extracts,and studied the stability of chlorophyll extractives in four extracts.The results indicated that chlorophyll absorption spectrum was similar in four extracts,accorded with the formula of Arnon to estimate the chlorophyll content.In addition,rubbing technique was better than marinating technique in efficiency of chlorophyll extractives,which was good for rapid determination of algal chlorophyll content.95% ethanol was better than other extracts,but the chlorophyll concentration was less and the stability was worse. |
