• In order to invesigate another function such as food in Morokheiya, the angiotensin-converting enzyme (ACE) inhibitor was extracted with 80% ethanol from the leaves of Morokheiya (<I>Corchorus olitorious</I>). The extract was dried, dissolved in water, defatted with ether and decolored with activated carbon. The ACE inhibitor was purified by successive ion-exchange chromatography, Amberlite IR-120B, Dowex 50W-X8 and Dowex 1-X4, respectively. The ACE inhibitor was further purified by silica gel column chromatography and finally purified and isolated by high performance liquid chromatography (HPLC) on Asahipak NH2P-50. The ACE inhibitor showed a positive ninhydrin reaction and no significant absorbance. The present ACE inhibitor was identified as Nicotianamine based on the comparative study using amino acid analyzer, TLC and capillary electrophoresis.
