From the root of Scutellaria repens BUCH.-HAM ex D. DON, two new flavonoids (10,11) and three new phenylethanoids (12-14) were isolated, together with nine known compounds. The structures of 10-14 were shown to be 5,7,2'-trihydroxy-6,8-dimethoxyflavone, O-5-hydroxy-6,8-dimethoxyflavone-7-yl β-D-glucuronopyranoside, O-2-(3-hydroxy-4-methoxyphenyl) ethyl O-2,3-di-O-acethyl-α-L-rhamnopyranosyl-(1→3)-(4-O-trans-feruloyl)-β-D-glucopyranoside, O-2-(3-hydroxy-4-methoxyphenyl) ethyl O-α-L-rhamnopyranosyl-(1→3)-(4-O-cis-feruloyl)-β-D-glucopyranoside and O-2-(3-hydroxy-4-methoxyphenyl)-ethyl O-2,3-di-O-acethyl-α-L-rhamnopyranosyl-(1→3)-(4-O-cis-feruloyl)-β-D-glucopyranoside, respectively, on the basis of the chemical and spectral data.
