THE STRUCTURE OF GANHUANGENIN, A NEW FLAVONOID FROM THE ROOT OF GANSUHUANGQIN (SCUTELLARIA REHDERIANA)

This paper reports the isolation and structure determination of a new flavonoid named ganhuangenin and characterization of four other known components from the root of Scutellaria rehderiana. Ganhuangenin was elucidated as 5,7,3′,6′-tetrahydroxy-8,2′-dimethoxyflavone on the basis of spectroscopic analysis (UV, IR, MS,¹H and ¹³C NMR). The known flavonoids were identified as baicalin, wogonin, baicalein and oroxylin-A.
