Three new flavonoid glycosides, 5,7,2'-trihydroxy-6-methoxyflavone 7-O-β-D-glucuronide methyl ester, 5,7,2'-trihydroxy-6-methoxyflavone 7-O-β-D-glucoside and 5,7,2',6'-tetrahyroxyflavonol 2'-O-β-D-glucoside, along with eleven known flavonoids and two known phenyl ethanoid glycosides, were isolated from the roots of Scutellaria amoena. Their structures were determined by spectral and chemical methods.
