Genetic characterization and phytochemical analysis of wild and cultivated populations of Scutellaria baicalensis.

Scutellaria baicalensis was collected from four wild and four cultivated populations from different locations in China. Forty-two samples were analyzed using random amplification of polymorphic DNA (RAPD) techniques for genetic profiling, and high performance liquid chromatography (HPLC) techniques to determine the flavonoid content. The selected 23 RAPD primers yielded a total of 838 clear and reproducible bands of which 237 were found to be polymorphic.
