The aerial part of the plant Scutellaria intermedia Popov yielded five glucuronides, three of which were identified as chrysin 7-O-β-D-glucuronide, wogonin 7-O-β-D-glucuronide, and baicalein 7-O-β-Dglucuronide (baicalin). IR, UV, PMR, and 13C NMR spectral data and acid hydrolysis of the two new glucuronides established their structures as 5,7,2′-trihydroxyflavone 2′-O-β-D-glucuronopyranoside (4) and scutevulin 2′-O-β-D-glucuronopyranoside (5).
