紫萍

电镜观察发现，经过UV-B辐射处理20天，紫萍叶状体叶肉细胞的膜结构受到破坏，可能膜脂过氧化和活性氧自由基起了重要作用。

The electrolyte leakage from the duckweed 's cell increased by enhanced UV-B radiation with the increasing time of treatment . Perhaps lipid peroxidation is one of the causes of membrane damage , and reactive oxygen species ( ROS ) were involved in the process .

主要研究成果有以下几点：结果表明，紫萍的抗癌活性主要来自于其中所含的黄酮类化合物。

The major contents and results of the research are as follows .
