Abstract: α-Amylase Inhibitors were isolated from Ficus sp. (Gameleira) seeds by acetone fractionation and Sephadex G-50. Two inhibitors (α-PPAI and α-ZSAI) were tested against α-amylases from coleopteran larvae. α-PPAI was active to α-amylases of Callosobruchus maculatus (52%) and Zabrotes subfasciatus (53%). α-ZSAI was strongly active to Z. subfasciatus (100%) of and Mimosestes mimosae (98%). The α-ZSAI is a glycoprotein of ∼50kDa with an IC50 value of 0.074 μg μl-1.
