Abstract
Platycerium bifurcatum is an epiphytic plant that belongs to the Polypodiaceae family.
Other species such as P. superbum, P. stemaria have been reported as potential sources
of antioxidants, antibacterial, anti-inflammatory and anticancer, but information and
research on the potential bioactivity of P. bifurcatum is still very limited and rare. This
research aims to determine the antioxidant extract of P.bifurcatum. The method used in
the isolation process is the maceration method with methanol solvent then partitioned
with n-hexane, dicloromethane, and ethyl acetate. Antioxidant assay results with 1,1-
diphenyl-2-picrylhydrazyl (DPPH) method obtained with AAI value in aqueous extract
(4.7), ethyl acetate extract (1.6) n-hexane extract (0.2) and dichloromethane extract (0.3).
The conclusion of the research according to the AAI value obtained is that the water
extract has very strong antioxidant activity, the ethyl acetate extract has moderate
antioxidant activity, and the n-hexane and dichloromethane extracts were classified with
weak antioxidant activity.
