Bio-potency of serine proteinase inhibitors from Cowpea (Vigna unguiculata) seeds on digestive proteinases and the development of Spodoptera littoralis (Boisduval)
Serine protease inhibitors (PIs) have been described in many plant species and are universal throughout the plant kingdom, where trypsin inhibitors is the most common type. In the present study, trypsin and chymotrypsin inhibitory activity was detected in the seed flour extracts of 13 selected cultivars/accessions of cowpea. Two cowpea cultivars, Cream7 and Buff, were found to have higher trypsin ... Read more
