8-Hydroxytricetin 7-glucuronide, a β-glucuronidase inhibitor from Scoparia dulcis

Abstract A new flavone glycoside has been isolated from Scoparia dulcis together with 11 known compounds. The new glycoside was determined as 5,7,8,3′,4′,5′-hexahydroxyflavone glucuronide by spectral analysis. The new glycoside and isovitexin showed inhibitory activity against β-glucuronidase.
