*Compounds have also been reported in the aerial parts(stems and leaves)of S.baicalensis.

The history of flavonoid study in S.baicalensis began in1930 when K.Shibata and S.Hattori first identified baicalin from the roots of this plant[11].Flavones are the most dominant type of flavonoids from the roots of S.baicalensis(Table 1).They include baicalein(5,6,7-trihydroflavone),baicalin(baicalein-7-O-glucuronide),chrysin(5,7-dihydroxyflavone),norwogonin(5,7,8-trihydroxyflavone),oroxylin A(5,7-dihydroxy-6-methoxyflavone)and wogonin(5,7-dihydroxy-8-methoxyflavone)(Fig.2) .Glycones(e.g.baicalin,scutellarin and wogonoside)are more common than aglycones(e.g.baicalein,scutellarein and wogonin).Most of the flavones are derivatives with methoxyl and hydroxyl groups.
