To determine the DPPH free radical scavenging activity and assay of four bioactive components: baicalin, baicalein, wogonin and wogonin 7 O glucuronide by HPLC.
Among them, the transition metals promoted dearomatization proceed under mild reaction conditions with various substrates, and which could be applied for synthesis of bioactive compounds.
The toxins of some specimens are also being studied as a source of bioactive products with different properties: Antibacterial, Enzymatic, Cytolytic, Immunostimulants, etc.
