Free Radical Scavenging and α-Glucosidase Inhibitor Activity of Ethanolic Extract of Mucuna pruriens L.

ABSTRAK: Velvet bean seeds are ubiquitous but  the scientific basis for its medicinal use especially as antioxidant and antidiabetic remains unknown. Therefore, a study was designed to evaluate  antioxidant  and  antidiabetic  activities  of  the    extract,  hexane,  ethyl  acetate,  butanol  and water fractions  of velvet bean seeds.  In order to evaluate antioxidant  activity  of  extract and fractions    using    quercetin,    butylated  hydroxyanisole  (BHA)  as  positive  control  and  1,1-diphenyl-2-picryl-hydrazyl  (DPPH)  free  radical  scavenging  activity  was  determined.  The results  showed  that  IC50  of  DPPH  were  22.17;  152.60;  113.03;  4.93;  9.14  μg/mL respectevily;    quercetin  4.28  and  BHA  22.587  μg/mL.   Antidiabetic  activity  was  determined by using  of α-glucosidase inhibition assay of  extract, four fractions and glucobay as positive control. The results showed that antidiabetic IC50 were24.44; 19.55; 8.40; 80.98; 48.97μg/mL respectively and glucobay as positive control  16.23 μg/mL.
