This study aimed to obtain an acetone extract of BC and investigate its inhibitory effects on carbonic anhydrase (CA) I, CA II, acetylcholine esterase (AChE), and butyrylcholine esterase (BChE) enzymes. We determined IC50 values of BC for each enzyme to measure the level of inhibition. The IC50 values for CA I and CA II were 8.77 μg/mL and 7.56 μg/mL, respectively. Acetazolamide, a specific CA I and II inhibitor, had IC50 values of 1.65 and 0.016 μg/mL, respectively. The IC50 values of BC for AChE and BChE were 7.96 and 8.58 μg/mL, respectively. Galantamine had IC50 values of 4.68 and 16.07 μg/mL for AChE and BChE, respectively. These results indicate that BC extract has a high potential to provide new drug candidates for all the tested enzymes, particularly for BChE.
