About 12 glycosides prepared through amyloglucosidase catalysis and 23 amino acylesters of carbohydrates prepared through lipase catalysis in organic solvents showed angiotensin converting enzyme (ACE) inhibition activity. Both amino acylesters of carbohydrates and glycosides exhibited IC50 values for ACE inhibition in the 0.5 mM to 15.7 mM range. Eugenyl-D-glucoside (IC50: 0.5+/-0.04 mM), L-isoleucyl-D-glucose
