| Summary: | This study investigates the total phenolic content and scavenging activity of the water
and methanol extracts of the stems of Mas Cotek (Ficus deltoidea var angustifolia). The
Folin-Ciocalteu reagent was used in determining the total phenolic content. The water
extract showed a higher value of total phenolic content (350 mg/g) compared to the
methanol extract (135 mg/g). The scavenging activity was measured using the 1,1-
diphenyl-2-picrylhydrazyl (DPPH) methods. The water extract showed 59.64 %
scavenging effect while 44.90 % for methanol extract at concentration of 2500 and 6250
ppm, respectively. As a conclusion, the water extracts from the stems of Mas Cotek
(Ficus deltoidea var angustifolia) has greater scavenging activity than the methanol
extract. Both water and methanol extracts showed lower value than the standard
quacertin. This indicate that the scavenging potential for both extracts were not as
effective as in quacertin. Further work need to be done in order to assess the full
antioxidant potential toward the stems of the plant. |
