Abstract:Aim To study the chemical constituents of the radix of Scutellaria baicalensis G. Methods The compounds were separated and purified by column chromatography and their structures were established by spectroscopic methods. Results Nine known compounds were isolated from the n-butanol layer extraction of Scutellaria baicalensis G. Their structures were determined as wogonin (1), oroxylin-A (2), phenylethyl acid (3), 2-(4-hydroxyphenyl)ethyl-O-β-D-glucopyranoside (4), 4-O-β-D-glucosyl-trans-p-coumaric acid (5), 4-O-β-D-glucosyl-cis-p-coumaric acid (6), baicalin (7), baicalein-7-O-β-D-glucopyranoside (8), baicalein-7-O-β-D-glucuronopyranoside methyl ester (9). Conclusion Compounds 3, 5 and 6 were isolated from Scutellaria baicalensis G. by the first time.
Keywords:Scutellaria baicalensis G.   structural identification  column chromatography
