This study was researched to purify and characterize variety bioactive material acethylmannan from Aloe vera. Purified acethylmannan was mannose (67%), acetyl group (23%) and the rest glucose, galactose that consisting of long chain polydispered ${\beta}-1,4$ linked mannan polymers. The sugar and acetyl group in molecular were linked molar ration one third. $IC_{50}$ value (i.e that concentration which exhibits 50% more enzyme inhibition than control) on angiotensin converting enzyme were 0.58 mM. This compound were found to be a competitive inhibition of Angiotensin Converting Enzyme with apparent Ki values of 0.068 mM.
