Abstract
New glycosides of baicalein (1–4) and wogonin (5 and 6) were found by studying phenolic compounds from roots of Scutellaria baicalensis Georgi (Lamiaceae) grown with treatment by 24-epibrassinolide. The new compounds were baicalein 7-O-(2′′-O-β-D-glucosyl)-β-D-glucuronopyranoside (scutellariside III, 1), baicalein 6-O-β-D-glucopyranoside-7-O-(2′′-O-β-D-glucosyl)-β-D-glucoronopyranoside (scutellariside IV, 2), baicalein 6-O-β-D-glycopyranosyl-7-O-β-D-glucuronopyranoside (scutellariside V, 3), baicalein 7-O-(2′′-O-malonyl)-β-D-glucuronopyranoside (scutellariside VI, 4), wogonin 7-O-(2′′-O-β-D-glucosyl)-β-D-glucuronopyranoside (scutellariside VII, 5), and wogonin 7-O-(2′′-O-malonyl)-β-D-glucuronopyranoside (scutellariside VIII, 5) according to UV and NMR spectroscopic and mass spectrometric data.
