—Part of hypotheses point out the quantity of plant secondary metabolites will increase in order to adapt environmental stress. Secondary metabolites accumulation of scutellarin in Erigeron breviscapus was investigated under different heavy metal stress. The results showed that exposure to cadmium, chromium and mercury stress scutellarin content of stem was higher sometimes, but its change from stress of copper and arsenic were opposite. In leaf and flower, scutellarin concentration was also decrease rapidly. So we inferred that after toxic substances entry into plant body, level of some secondary metabolites will exhibit decrease trend in some extent, and not only enhanced any time. Therefore, the change of secondary metabolites in medicine plant should attract more attention under stress environment in future.
