title: Potential ecological roles of flavonoids from Stellera chamaejasme.
abstract: Stellera chamaejasme L. (Thymelaeaceae), a perennial weed, distributes widely in the grasslands of Russia, Mongolia and China. The plant synthesizes various secondary metabolites including a group of flavonoids. To our knowledge, flavonoids play important roles in the interactions between plants and the environment. So, what are the benefits to S. chamaejasme from producing these flavonoids? Here, we discuss the potential ecological role of flavonoids from S. chamaejasme in protecting the plant from insects and other herbivores, as well as pathogens and competing plant species, and new data are provided on the phytotoxicity of flavonoids from S. chamaejasme toward Poa annua L.
