Baicalin-beta-D-glucuronidase (, baicalinase) is an enzyme with systematic name 5,6,7-trihydroxyflavone-7-O-beta-D-glucupyranosiduronate glucuronosylhydrolase. This enzyme catalyses the following chemical reaction
The enzyme also hydrolyses wogonin 7-O-beta-D-glucuronide and oroxylin 7-O-beta-D-glucuronide with lower efficiency.
