[Chemical constituents and their biosynthesis mechanisms of Polygonum cuspidatum].

This article reviews the research progress of the chemical constituents and biosynthesis mechanisms of Polygonum cuspidatum. The chemistry components isolated from P. cuspidatum are mainly anthraquinones, naphthoquinones, stilbenes, flavonoids, and other compounds. The synthase genes involved in the biosynthesis process were summarized. The biosynthesis mechanism of stilbenes and anthraquinones was discussed. This article hopefully to provide a reference for further research, development and utilization of P. cuspidatum.
