We evaluated the enzyme inhibitory activity of germinated rough rice (Oryza sativar L.) treated by high pressure (30MPa) for 24 h (HP24) and 48 h (HP48). In rice germinated for 1 day, the ${\alpha}$-glucosidase inhibitory activity reached its highest level, 68.32%, at HP48. The ${\alpha}$-amylase inhibitory activity increased from 32.66-57.00% at HP0, to 43.67-74.82% at HP48. On the other hand, the inhibitory activity of angiotensin-converting enzyme increased from 27.98% to 49.42% over the course of the second day of HP48. The inhibitory activity of xanthine oxidase peaked of 67.51% at HP48 and subsequently decreased. Lipase inhibitory activity increased from 24.04-47.91% at HP0, to 29.62-64.63% at HP48. These results provide useful information for the use of germinated rough rice as a functional food material and demonstrate that high-pressure treatment during the germination process efficiently increase enzyme inhibitory activity.
