Procedure

50 μl of a solution containing 0.01 mole/liter of hippuryl-histidyl-leucine (substrate) and 0-100 μl of a test compound solution were added to 300 μl of a 0.2M tris-hydrochloric acid buffer solution containing 0.2 mole/liter of sodium chloride. The total volume of said mixture was adjusted to 450 μl with water. Then, 50 μl of angiotensin-converting enzyme (ACE) isolated from pig's renal cortex were added to the mixture, and the mixture was allowed to stand at 37° C. for 20 minutes. The amount of histidyl-leucine produced from the substrate by the action of ACE was assayed microbiologically by the use of Leuconostoc mesenteroides P-60, and the ACE-inhibitory activity of the test compound was estimated therefrom. The results are shown in the following Table 1.
