采用原子吸收分光光反法测定芦荟叶片中的镁含量，从而间接计算出花叶中叶绿素的含量。并对测定过程中有机萃取剂，反萃酸度的选择及干扰离子的影响进行了探讨。
The atomic absorption spectrophotometry was used to determine the content of magnesium in leaves of aloe, thus indirectly calculating the content of chlorophyll in the leaves. In the process of determination, the choice of organic extractant, stripping acidity and the influence of interfering ions were discussed.
