Dalcochinin-8'-O-β-D- glucoside is well hydrolyzed by Thai Rosewood β-glucosidase (K(m) 1.68 mM), but not by other β-glucosidases, such as cassava stem linamarase, almond β- glucosidase, or mustard seed myrosinase.Mahidol UniversityAgricultural and Biological SciencesBiochemistry, Genetics and Molecular BiologyChemistryPharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1016/S0031-9422(98)00552-4
