The treatment of flax cotyledons (Linium usitatissimum) with paraquat was shown to decrease the levels of chlorophyll and carotenoid pigments. The fatty acid content of chloroplast fragments isolated from treated tissue was determined and shown to be greatly decreased by paraquat treatment. The superoxide radical was demonstrated to play an important role in the phytotoxic action of paraquat by the use of a copper chelate of D-penicillamine, which has a high superoxide is discussed with reference to the generation of more toxic species, such as singlet oxygen.
用百草枯处理亚麻子叶（亚麻）可降低叶绿素和类胡萝卜素色素的水平。测定了从经处理组织中分离出的叶绿体片段的脂肪酸含量，结果表明百草枯处理使其大幅降低。通过使用D-青霉胺的铜螯合物证明超氧自由基在百草枯的植物毒性作用中起重要作用，该螯合物具有高超氧，文中还参照单线态氧等毒性更强的物质的生成进行了讨论。
