摘　　要：植物与手性化合物存在着非常密切的联系.一方面,植物分泌、合成的一些手性化合物,如糖甙、酶、萜类化合物、有机酸及植物激素等,在植物的生理生化过程中起着重要的作用;另一方面,人工合成的手性化合物尤其是农药等环境污染物与植物具有对映体选择性相互作用,它们或是选择性地抑制植物的生长和生理过程,或是被植物选择性地吸收和代谢.因此,在开发、生产和使用手性化合物时需要考虑植物与对映体之间的选择性因素;同时,合理利用植物对手性污染物进行环境修复也具有重要意义.本文对植物与手性化合物相互作用中的对映体选择性进行了综述,并对手性污染物的植物修复进行了展望.There exists a close relationship between plants and chiral compounds. On one hand, plants can secrete and synthesize some chiral compounds such as glucosides, enzymes, terpenoids, organic acids and phytohormones that play important roles in plant physiological and biochemical processes, and on the other hand, artificial synthetic chiral compounds, especially pesticides, had enantioselective interactions with plants. The pesticides can enantioselectively inhibit the growth of plants, or can be enantioselectively absorbed and metabolized by plants. Therefore, in the exploitation, production and application of chiral compounds, it＇ s needed to consider the enantioselective interaction between plants and chiral compounds. In the meanwhile, choosing appropriate plants to ameliorate the environment polluted by chiral compounds is of practical significance. In this review, the enantioselective interaction between plants and chiral compounds was summarized, and the amelioration of chiral compounds-polluted environment by plants was prospected.
