Abstract
Radikal bebas dapat disebabkan karena faktor intrinsik dan ekstrinsik. Faktor
ekstrinsik seperti kondisi cuaca, pengaruh kondisi lingkungan, terpapar sinar UV,
dan polusi dan dapat mengakibatkan kerusakan kulit, penuaan kulit terjadi lebih
cepat, kering, munculnya flek hitam. Antioksidan merupakan suatu senyawa yang
dapat meredam atau menangkal dampak negatif efek oksidan yang ada dalam tubuh
dengan cara mendonorkan satu elektronnya kepada senyawa yang memiliki efek
oksidan sehingga aktivitas senyawa oksidan dapat dihambat. Salah satu tanaman
yang mempunyai aktivitas antioksidan adalah tanaman sarang semut (Myrmecodia
tuberosa Jack) karena mempunyai kandungan senyawa flavonoid dan tanin.
Penelitian bertujuan untuk menguji aktivitas antioksidan dari ekstrak etil asetat
tanaman sarang semut (Myrmecodia tuberosa Jack) dengan menggunakan metode
1,1-Diphenyl-2-pycrylhydrazyl (DPPH). Sampel yang digunakan merupakan
tanaman sarang semut (Myrmecodia tuberosa Jack) sebanyak 5 kg yang diperoleh
dari Papua. Dalam pembuatan ekstrak dilakukan dengan metode maserasi
menggunakan pelarut etil asetat. Pada penelitian, dilakukan skrining fitokimia
untuk mengidentifikasi kandungan metabolit sekunder yang terdapat dalam suatu
tanaman yang akan diteliti. Ekstrak etil asetat tanaman sarang semut (Myrmecodia
tuberosa Jack) mempunyai kandungan senyawa metabolit sekunder seperti
flavonoid, saponin, dan tanin. Pada penelitian diperoleh % rendemen sebesar
1,6932% dan kadar air sebesar 8,14%. Pada pengujian antioksidan menggunakan
DPPH dengan parameter IC50 menunjukkan tanaman sarang semut (Myrmecodia
tuberosa Jack) memiliki aktivitas antioksidan kategori kuat dengan IC50. Nilai IC50
ekstrak yang diperoleh sebesar 22,0394 μg/mL dan IC50 vitamin C sebesar 8,6990
μg/mL menunjukkan bahwa aktivitas antioksidan ekstrak lebih lemah dibandingkan
antioksidan vitamin C. Aktivitas peredaman radikal bebas ekstrak etil asetat
tanaman sarang semut (Myrmecodia tuberosa Jack) lebih lemah dibandingkan
dengan vitamin C. / Free radicals can be caused by intrinsic and extrinsic factors. Extrinsic factors such
as weather conditions, the influence of environmental conditions, exposure to UV
rays, and pollution and can cause skin damage, skin aging occurs faster, dryness,
the appearance of black spots. Antioxidants are compounds that can reduce or
counteract the negative effects of oxidants in the body by donating an electron to
compounds that have oxidant effects so that the activity of oxidant compounds can
be inhibited. The aim of this study was to examine the antioxidant activity of the
ethyl acetate extract of ant nests (Myrmecodia tuberosa Jack) using the 1,1-
Diphenyl-2-pycrylhydrazyl (DPPH) method. The sample used was 5 kg of ant nests
(Myrmecodia tuberosa Jack) obtained from Papua. Secondary metabolites found in
ant nest plants (Myrmecodia tuberosa Jack) are flavonoids and tannins which have
potential as antioxidants. In the manufacture of extracts carried out by maceration
method using ethyl acetate solvent. In this study, phytochemical screening was
carried out to identify the content of secondary metabolites present in a plant to be
studied. Phytochemical screening conducted on the ethyl acetate extract of the ant
nest plant (Myrmecodia tuberosa Jack) showed the presence of secondary
metabolites such as flavonoids, saponins, and tannins. In this study, the % yield was
1.6932% and the water content was 8.14%. In the antioxidant test using DPPH with
the IC50 parameter, the ant nest plant (Myrmecodia tuberosa Jack) has a strong
category of antioxidant activity with IC50. The IC50 value of the extract obtained
was 22.0394 μg/mL and the IC50 vitamin C was 8.6990 μg/mL indicating that the
antioxidant power of the extract was weaker than the antioxidant vitamin C. The
free radical scavenging activity of the ethyl acetate extract of the ant nest plant
(Myrmecodia tuberosa Jack) weaker than vitamin C.
