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