Alcoholic and water extracts from seed‐coats of Vicia faba var. equina were prepared and their effects on in ‐ vivo intestinal sugar absorption across the rat small intestine were investigated. Both extracts significantly ( P <0.001) inhibited sugar absorption. The higher and more stable inhibition was induced by the water extract. Pretreatment of the extracts with polyamide significantly ( P <0.001) reduced their inhibitory potency but did not abolish it, suggesting the presence in the extracts of some other intestinal sugar absorption inhibitor, different from polyphenols. Although both extracts inhibited intestinal sugar active transport, only the water extract was able to reduce sugar diffusion across the small intestine. These differences in behaviour seem to be related to the polyphenolic content of each extract.
