Abstract
An isoflavonoid glucoside was isolated from the seeds of Thai Rosewood (Dal bergia cochinchinensis Pierre), and the aglycone was shown to be 12-dihydro amorphigenin, which we named dalcochinin. Dalcochinin-8'-O-beta-D-glucoside is well hydrolyzed by Thai Rosewood 8-glucosidase (K-m 1.68 mM), but not b y other beta-glucosidases, such as cassava stem linamarase, almond beta-glu cosidase, or mustard seed myrosinase.
