Abstract: PURPOSE: A manufacturing process for a low molecular weight of angiotensin converting enzyme(ACE) inhibitor from hot water extract of lettuce root is provided, which is an efficient and economical process. CONSTITUTION: The manufacturing process for a low molecular weight of ACE inhibitor from lettuce root comprises the steps of: removing an impurities by washing lettuce, separating its root, adding distilled water to the root, and extracting by making reflux for 2hrs at 100deg.C, 60deg.C; filtering, centrifuging for 30min. at 4deg.C, 8000rpm, and collecting the upper solution; ultra-filtering the upper solution using ultra-filter membrane(limit of M.W. is 1000) to prepare the extract; filtering through membrane filter paper, loading on high performance liquid chromatography, and separating a fraction, F4 with highest activity; and then gathering the F4, freeze-drying, and purifying using reversed phase HPLC.
