ANTIOXIDANT POTENTIAL OF HABISCUS CANNABINUS METHANOLIC LEAF EXTRACT

S.A. James, M.J. Ladan, D.J. Goje

Abstract


The antioxidant properties of Methanolic leaf extract of Hibiscus
cannabinus  (Malvaceae  family),  was  investigated  using  1,1-diphenyl-2-picryhydrazyl  (DPPH)  assay  method,  reducing
power  and  hydrogen  peroxide scavenging  effect  assays.  The
Methanolic leaf  extract, exhibited  significant scavenging  effect
on DPPH free radical and hydrogen  peroxide production at a
lower  concentration  of  the  extract  when  compared  with
ascorbic  acids  and  α-  tocopherol  standard  antioxidants.  The
highest  free-radical  scavenging  and  percentage  scavenging
effect of hydrogen peroxide by the Methanolic leaf extract was
observed  at  concentrations  31.25  and  250μg/ml  respectively;
with  76.03%  and  62.26%  inhibition/scavenging  effect
respectively. However, reducing power showed low activity for
the leaf extract
