Inhibitory activities in eight plant seed extracts were estimated against ten different pancreatic amylases. Maize had no inhibitory activity. Proso did not inhibit cat, rabbit, chicken, horse and pig amylases. It inhibited human (55.4 inhibitory units/mg protein), bovine (49.9), guinea pig (10.4), rat (11.6) and dog (7.1) amylases. Pearl millet that had no action on horse enzyme, had comparable activity (43.0–64.7 units/mg protein) on other amylases. Sanwa millet had low activity against horse amylase (3.8) compared to other amylases (10.8–37.5). Sorghum had low activity against horse (50.8 units/mg protein) and pig (69.7) enzymes compared to human and bovine amylases (278). Runner bean (8.0–12.0 units/mg protein) and Italian millet (39.5–83.7) had fairly comparable activities on all amylases. Red gram showed relatively high inhibitory activity (734–1260 units/mg protein) against all amylases except that of pig (83.9).
