Abstract

The mechanism of antimutagenicity of water extracts of grass-wrack pondweed (Potamogeton oxyphylus Miquel), curled pondweed (Potamogeton crispus L.) and smartweed (Polygonum hydropiper L.) towards benzo[a]pyrene mutagenicity in Salmonella typhimurium was investigated. The antimutagenic components in the aquatic plants were water-soluble, heat-resistant and had a high molecular weight; chlorophyll did not play an important role.

摘要

研究了龙须眼子菜（Potamogeton oxyphylus Miquel）、菹草（Potamogeton crispus L.）和水蓼（Polygonum hydropiper L.）水提取物对鼠伤寒沙门氏菌中苯并[a]芘诱变性的抗诱变机制。水生植物中的抗诱变成分是水溶性的、耐热的且分子量高；叶绿素不起重要作用。
