Mobola plum seed methanolic extracts exhibit mixed type inhibition of angiotensin -converting enzyme in vitro

Objective To explore the possible inhibitory potentials and mechanism by Mobola plum (Parinari curatellifolia) seeds crude methanol (CE) and flavonoid-rich (FE) extracts on angiotensin-1-converting enzyme (ACE ). Methods The sensitivity and kinetic model of inhibition of CE and FE on ACE using N-[3-(2-furyl)-acryloyl]-Phe-Gly-Gly as enzyme substrate for ACE was evaluated by Michealis Menten approach. The inhibition mechanism was explored from Lineweaver–Burk model and IC
