Abstract: Five new flavonoid glycosides named as amoenins A - E together with eight known compounds di-hydrobaicalin, chrysin -8-C-β-D- glucopyranoside, chrysin 6-C-β-D- glucopyranosyi - 8 - C -α- L- arabinopyranoside, (trans)-5, 7, 2', 6' - tetrahydroxyflavanonol, 5, 7, 2', 6'-tetra-hy-droxyflavanone, dibutyl phthalate, P- sitosterol and daucosterol, were isolated from the roots of Scutellaria amoena C. H. Wright. The structures of new glycosides were elucidated as 2', 4', 6' - trihydroxydihy-drochalcone 4'- [0-β-D-glalactopyranosyi (l→ 2 )]- 0- β- D- glucopyranoside, 5, 7, 2'- tri-hydroxy - 6 - methoxyflavanone 7-0-β-D- glucuronopyranoside, ( cis ) - 2', 5, 7 - trihydroxyfla-vanonol 3-0-β-D- glucopyranoside, (trans) - 2', 6', 5, 7 - tetrahydroxyflavanonol 3 - 0 - β - D - glucopyranoside and ( cis) - 2', 6', 5, 7 - tetrahydroxyflavanonol 3-0-β-D- glucopyrano - side by based on spectral analysis, respectively.
