Uji Aktivitas Antioksidan Tiga Spesies Tanaman Sarang Semut (Famili: Rubiaceae) Asal Kabupaten Merauke, Papua
ABSTRACT: Sarang semut plant
is one of indigenous medicinal plants of Merauke region, the Papua province. Local people use the
bulb of sarang semut plants to cure inflammation, muscle pain and enhancing
immunity. However rare research of the plants has been done especially on the
antioxidant activity. The objective of this research was to investigate the antioxidant activity of
three species of sarang semut
plants which were Myrmecodia
beccarii, Myrmecodia sp. and Hydnophytum sp. The test was
necessary to identify the inhibitory concentration level of plant extract in
blocking a free radical (IC50).
Parts of plants
were extracted with
maceration using methanol
for 3 x
24 h to
produce concentrated methanol. Plant extracts of three species were then subject to antioxidant activity
test based on free radical blocking of
1,1-Difenil-2-Pikrilhidrazil
(DPPH) qualitatively and
quantitatively using Ultraviolet -Visible spectrophotometry. The
results showed the methanol extract
of M. beccarii,
Myrmecodia sp. and Hydnophytum sp.were active
as antioxidants with IC50
from 8.18 ppm,
21.79 ppm, 25.31
ppm, respectively while
Vitamin C as a control
has IC50 7.85 ppm. In conclusion, three
plant species of sarangsemut are potential as natural antioxidant and plant
extracts of M. beccarii showed the highest antioxidant activity among others.
