Abstract
An alcoholic extract obtained from the rhizomes of Gloriosa superba Linn (Colchicaceae) was screened for enzyme inhibition activities. The crude extract and its subsequent fractions including chloroform, ethyl acetate, n-butanol and aqueous were screened against lipoxygenase, actylcholinesterase, butyrylcholinesterase and urease. An outstanding inhibition on lipoxygenase was observed. The highest enzyme inhibition potency was expressed by the chloroform fraction (90%) among the tested fractions on lipoxygenase. Overall 67– 90% inhibition was found for lipoxygenase, 46-69% for acetylcholinesterase and 10–33% for butyrylcholinesterase, while urease was not inhibited.
