Description |
The role of seed polyphenols of chickpea and pigeonpea in enzyme inhibitory activities of trypsin, chymotrypsin and a-amylase was examined by in vitro methods. Polyphenols were extracted from whole seed samples by refluxing with acidified methanol. Chickpea polyphenols inhibited trypsin more than chymotrypsin whereas pigeonpea polyphenols did not show such a distinction. on the basis of the average percent enzyme inhibition in the various cultivars studied, pigeonpea polyphenols were found to be more effective than those of chickpea. The addition of polyvinylpyrrolidone (PVP) remarkably reduced the enzyme inhibitory property of the polyphenols. The polyphenolic compounds of cultivars with dark testa color showed more inhibitory activity than those with light testa color in both chickpea and pigeonpea. Since carbohydrates and proteins are the principal seed constituents of these pulse crops, the observed results have nutritional implications in terms of utilization of these constituents. |
