biologically active components; broad bean seeds
Selected biologically active non-nutrient components (BANS) were determined in broad bean seeds of fine-size and large-size seed varieties and in pea seeds for comparison. Among the analysed biologically active substances the broad bean seeds of fine-size and large-size seed varieties were differentiated mainly by phenolic compounds (including flavanols and proantocyanidines) which appear in twice as large quantities in large-size seed varieties. It was shown that in comparison to pea, broad bean seeds are characterised by a higher content of phenolic compounds, phytates as well as a higher activity of inhibitors of trypsin and amylases. Moreover, it was found that phenolic compounds accumulate mainly in the dark-colored seed coats of large-size broad bean and this fact is related to higher activity inhibiting alpha-amylases of methanol extracts from this fraction of seeds.
