Abstract
Angiotensin I-converting enzyme (ACE) inhibitory peptide was isolated and identified from buckwheat (Fagopyrum esculentum Moench). Buckwheat protein extract was prepared by stirring in water (pH 9.0) for 30 min, followed by centrifugation at 15,000g for 20 min. The protein extract was then filtered using an YM-10 membrane. An ACE inhibitor was purified using consecutive chromatographic methods including: ion-exchange chromatography, gel filtration chromatography, and reverse-phase high performance liquid chromatography. The ACE inhibitor was identified to be a tripeptide, Gly-Pro-Pro, having IC50 value of 6.25 μg protein/ml, by protein sequencing system and electrospray-LC–mass spectrometry.
