title: [Studies on the Nepalese crude drugs. XIX. On the flavonoid and phenylethanoid constituents of the root of Scutellaria repens Buch.-Ham. ex D. Don].
abstract: 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 beta-D-glucuronopyranoside, O-2-(3-hydroxy-4-methoxyphenyl)ethyl O-2,3-di-O-acethyl-alpha-L-rhamnopyranosyl- (1-->3)-(4-O-trans-feruloyl)-beta-D-glucopyranoside, O-2-(3-hydroxy-4-methoxyphenyl)ethyl O-alpha-L-rhamnopyranosyl-(1-->3)-(4-O-cis-feruloyl)-beta-D-glu cop yranoside and O-2-(3-hydroxy-4-methoxyphenyl)-ethyl O-2,3-di-O-acethyl-alpha-L-rhamnopyranosyl- (1-->3)-(4-O-cis-feruloyl)-beta-D- glucopyranoside, respectively, on the basis of the chemical and spectral data.
