Na2FlBr4Cl4 shows the maximum algaecidal activity, and the MLC value is 40μM with illumination and 90μM without illumination. From the research on the Na2FlBr4Cl4 against the growth of algae and the content of chlorophyll a, we obtains that xanthene derivatives have little effect on the growth of algae at low concentration and can restrain the growth of algae at middle and high concentration.

呫吨类化合物对铜绿微囊藻的测试结果显示：供试样品中对供试藻种活性最强的是Na2FlBr4Cl4，其MLC值为在光照条件下为40μM，在无光条件下为90μM；通过Na2FlBr4Cl4对铜绿微囊藻的生长量以及叶绿素a含量的影响的研究发现，在较低的浓度范围内，呫吨类化合物对铜绿微囊藻的生长没有太大影响，而在中高的浓度范围内，则能产生显著的抑制效应。

In the second part, the structure of agglutinin from Abrus precatorius has been determined by X-ray crystallography. The structure and the activity as a ribosome-inactivating protein have been compared with abrin-a from Abrus precatorius.

第二部份是以X光结晶学的方法，决定鸡母珠凝集素(Agglutinin from Abrus precatorius)的单晶结构，描述其与鸡母珠毒素(Abrin-a from Abrus precatorius)结构上的差异，并试图由此分析两者作为醣体抑制蛋白在活性上的差异。
