A novel angiotensin I-converting enzyme (ACE) inhibitory peptide from a marine Chlorella ellipsoidea and its antihypertensive effect in spontaneously hypertensive rats

► This study was to purify an ACE inhibitory peptide derived from Chlorella ellipsoidea. ► Protein derived the Chlorella ellipsoidea was hydrolyzed using different proteases. ► Oral administration of the peptide lower blood pressure in SHR.
