This study determined the antioxidant activity of extracts from four Indonesian medicinal plants - mahkota dewa, temu putih, sambiloto, and keladi tikus - using the thiobarbituric acid method. Extracts were prepared using water and ethanol. The extracts were tested for their ability to inhibit the oxidation of linoleic acid, which was measured by analyzing the amount of malondialdehyde produced. Water and ethanol extracts of all four plants showed antioxidant effects, with inhibition levels ranging from 60-85% at a concentration of 200 ppm. The antioxidant activity of the plant extracts was significantly lower than that of vitamin E, which inhibited oxidation by 87% at the same concentration.

those plants. According to various researches
recently, mahlwta dewa flesh contains
flavonoids, alkaloids, terpenoids, saponinns,
and resins (Harmanto 2002; Winarto 2003).
The utilization of above plants mostly is
empirical evidence based on users' experiences
and the scientific evidence. Thus, the scientific
research especially for the antioxidant potency
of these plants is important to perform.
The purpose of the research is to determine the
antioxidant activity of mahkota dewa, temu
pUlih, sambi/oto, and keladi tikus in vitro by
thiobarbituric acid (TBA) method. This study
also is expected to give scientific informations
about the antioxidant potent of these plants.
METHOD
Analysis of hydroperoxide from linoleic
acid by thiocyanate method (Chen el al.
1996)
Before the measurement of the antioxidant
potency from each extract, it was measured the
hydroperoxide as primary product of oxidized
linoleic acid by thiocyanate method. This
method measures the peroxide through color
complex of Fe[Fe(SCN)6J.
Amount of 2 mL of phosphate buffer 0.1 M
pH 7.2 mL of linoleic acid 50 mM in ethanol
99.8% and I mL of deionized water were
placed into dark bottle, the the mixture was
incubated at 40°C. The period of incubation
time was until reached the maximum
absorbance.
.~fter the maximum absorbance was reached,
into 50 JlL of incubated mixture, it was added
6 mL of ethanol 75%, 50 JJ.L of ammonium
thiocyanate 30%, and 50 JlL of FeCh 0.02 M
in HCI 3.5%. After left for 3 minutes, the
3bsorbance was measure at a wavelength 482
;lm. The measurement of hydroperoxide was
-.:arried out every day until the maximum
absorbance was reached.
Analysis of antioxidant potency by TBA
method (Kiuzaki & Nakatani 1993)
Analysis of antioxidant capability from each
extract was carried out using serial
concentration of sample test solution, namely
50, 200, and 1000 ppm. Standard solution of
I, ,3,3-tetramethoxy propane (TMP) 6 M was
diluted into serial concentration of 0.15, 0.3,
0.6, 0.75, 1.5, and 3.0 JlM. Each solution was
taken I mL and added 2 mL TCA 20% and 2
mL TBA 1% (b/v) in acetate solvent 50%
(v/v). Next, all of test tubes were incubated at
100°C for 10 minutes and cooled at room
temperature. Once cool, the mixtures were
centrifuged at speed 300 rpm then the
absorbance was measure uSing
spectrophotometer at a wavelength 532 nm
(Yagi 1968).
Sample solution was prepared from mixture
containing of 2mL of phosphate buffer pH 7.2
mL of linoleic acid 50 mM in ethanol 99.8%
containing tocoferol (Vitamin E 200 ppm), and
I mL ofdeionized water.
All of the reaction mixtures were incubated in
water bath 40°C with the period of incubation
time was based on the measurement of
hydroperoxide from linoleic acid. Reaction
mixtures were assayed for antioxidant potency
after 1 or several days from the maximum
absorbance of linoleic acid. Each reaction
mixture was taken I mL then added 2 mL of
TCA 20%, and 2 mL of TBA I% solution in
acetic acid 50% solvent. Next those reaction
mixtures were placed in waterbath 100°C for
10 minutes. After cool, centrifuged at 300 rpm
for 15 minutes, then the absorbance was
measured using spectrophotometer at a
wavelength of 532 nm.
RESULTS AND DISCUSSION
Linoleic acid oxidation
Antioxidant activity assay by TBA method is
based on measurement of malondialdehida
(MDA), level which is the end product of lipid
peroxide reaction. MDA is a reactive three­
carbon dialdehyde compounds. MDA
generated can be measured by TBA test. MDA
can react with TBA to form a product for
which fluorescence and can be measured at a

9. 41
wavelength of 532 nm. As a standard, it is
used 1,1,3,3 tetrametoksipropana (TMP) that
can measure MDA formed level. TMP is an
MDA derivative compounds which is quite
stable. Measurement of antioxidant activity
with this TBA method were carried out after
the level of linoleic acid oxidation was
maximum because at that time also established
the maximum MDA generated from lipid
oxidation reactions.
Antioxidant activity of mahkota dewa, temu
putih, sambiloto, and keladi tikus can be
determined from its ability to inhibit oxidation
of linoleic acid. The presence of secondary
metabolites such as alkaloids, ftavonoids,
tannins, and saponins suspected to inhibit the
oxidation of linoleic acid. Hydroperoxide
measurement result which was the result of
oxidation of linoleic acid showed peak
absorbance at 6th
day.
Oxidized Linoleic acid by oxygen in the early
stages will form the hydroperoxide. This
hydroperoxide levels increased and after
reaching the maximum level, hydroperoxides
will decompose to form malondialdehyde
which is the end product of lipid peroxide
reaction. Malondialdehyde formation was
occurred on 7th day.
Antioxidant activity analysis
Measurement of antioxidant activity was
carried out on the 8th day in the hope that all
hydroperoxide formed from the oxidation of
linoleic acid had undergone decomposition
into maIondialdehyde (MDA). Antioxidant
activity of all types of plants can be seen by
comparing the absorbance value that describes
the concentration of MDA. Absorbance value
is proportional to the concentration of MDA
and inversely proportional to the antioxidant
potency. Low absorbance values indicate that
plants have a high antioxidant potential. This
indicates that the sample may inhibit the
oxidation process (means to reduce the amount
of MDA which reacts with the thiobarbituric
acid to form red product).
This study used vitamin E as standard with a
concentration of 200 ppm. The reason for the
selection of vitamin E as a standard was at a
concentration of 200 ppm inhibition
percentage was near 100%. The results of
Satna (2005), inhibition of vitamin E (200
ppm) by TBA method amounted to 93.0%,
while the results of research Indariani (2005)
the antioxidant potency of vitamin E (200
ppm) in inhibiting the oxidation of lipids up to
92.11 %. In this study, vitamin E with a
concentration of 200 ppm had inhibitory
amounted to 87.0 I%. The value of the
inhibition was greater than aquademineral, hot
water, and ethanol extract. This is because the
content of antioxidant compounds in the
vitamin E is more pure. From the results of
standard measurements of 1,133- tetrametoxy
propane (TMP), obtained the linear regression
y = 0.0240 X + 0.0269, R = 99.82%. The
regression equation used to calculate the MDA
level of TBA test results for each extract.
Based on Salim (2006) research, obtained
three extracts of mahkota dewa, that were
extracted by solvent aquademineraL hot water,
and ethanol. After that, the three extracts were
tested antioxidant activity. Inhibition of plant
extracts tested, using a solvent aquademineral,
hot water and ethanol at concentrations of 50,
200, and 1000 ppm can be seen in Table 1.

Almost all of secondary metabolites are polar
compounds. Aquademineral have a level
higher polarity than ethanol. Aquademineral
extract (50 and 200 ppm) of mahkotu dewa
had a higher antioxidant activity than the hot
water and ethanol extract. This is due to the
ability of solvent extraction is directly
proportional to the level of purity of the
solvents. In this case aquademineral is more
pure than hot water. While the ethanol extract
(1000 ppm) had higher potency compared with
aquademineral extract and hot water. This is
due to the concentration of extract
concentration had reached maximum standard
limit (Vitamin E 200 ppm), so it is believed
that there were other compounds been
extracted.
quademinerat extracts of mahkota dewu had
.1 good antioxidant activity at concentration of

allegedly many secondary metabolites are

the influence of temperature and chemical
compounds content ill each extract tested were
different. These factors cause the type of
solvent that is able to extract the maximum
yield is not the same for cach type of plant
extracts tested, so the results of lemu putih and
mahkola dewa inhibition was different. Based
on Pratiwi (2006) research, the phytochemical
test: alkaloids and t1avonoids showed positive
test results. These compounds are believed to
act as antioxidants to inhibit lipid peroxide

content of secondary metabolites such as
alkaloids, tannins, saponins, and flavonoids
contained in the aquademineral extract was
quite large. Based on Puspitasari (2006)
research, the phytochemical test: alkaloids and
terpenoids showed positive results for all three
types of solvent. While t1avonoids showed
negative results only on ethanol and tannin
only in the solvent of aquademineral.
Inhibition at a concentration of 200 ppm for
aquademineral and hot water extract had the
same value. This showed that aquademineral
and hot water extract had the same inhibitory

Antioxidant activity of each of these extracts

with vitamin E (200 ppm) still looked much
lower (Figure 1). Despite this difference
between the antioxidant potency of each
extract at a concentration Of 50, 200, and 1000
ppm was not so visible. This was because the
concentration of the extract was too large and
not proportional to the concentration of
linoleic acid substrate.
Antioxidant activity of keladi tiku.~ extract.
Aquademineral extract of keladi tikus (50
ppm) had higher antioxidant activity than the
hot water and ethanol extract (Figure 4). This
is because aquademineral has a high level of
polarity than ethanol and more pure than hot
water, so that alleged some secondary
metabolites such as alkaloids and flavonoids
that have a high level of polarity are also
distributed in it. Based on Affandi (2006)
research, the phytochemical test: alkaloids,
tlavonoids, and tannins showed positive
results. These compounds are an antidote
compound which can inhibit free radical
oxidation reactions.

Antioxidant activity of keladi tikus
At a concentration of 200 ppm ethanol
extraction had a higher inhibitory This was
due to the compounds contained in extracts of
keladi tikus distributed more on ethanol,
although the level of polarity lower than
aquademineral and hot water. Based on these
results we can conclude that the inhibition of
antioxidants is not always proportional to the
level of purity and polarity of the solvent used.
Meanwhile, at a concentration of 1000 ppm.
the inhibition of aquademineral and hot water
had the same value but higher than ethanol.
This was due at concentrations above the
maximum limit (200 ppm) the extract had
different antioxidant potential which was less
visible, making it difficult to distinguish the
influence of the purity and polarity of a
solvent.
Based on the results obtained, it was
concluded that mahkoJa dewa, lemu pulih,
samhiloto, and keladi tikus with three kinds of
extracts, namely aquademineral. hot water and
ethanol were very potent antioxidants. This
can be seen at a concentration of 200 ppm, the
value of the inhibition of each extract was
close to the value of the inhibition of vitamin
E.
Alkaloids and flavonoids gave positive results
on all types of plants tested (Salim 2006).
Flavonoids and alkaloids is a good reductor
compound. Flavonoids act as a good container
for hydroxyl and superoxide free radicals
(Robinson 1995). Accord ing to Mangan
(2003), flavonoid substance served as an
antidote to free radicals that could disnJpt the
body's balance system and could lead to
cancer.
Tannins are compounds that contained in the
tea plant. Based on the Yen (1995) research, it
reported that various types of tea had
antioxidant activitv. Based on the results of the
study also tannin~ could inhibit the process of
mu~tion ~nd cancer, and free radicals and
induced enzymes that act as antioxidants.
Saponins in the plant have been known to be
used for treatment. Saponin contained in

contained in kunyil, tapak dara, sabung
nyawa, mengkudu, kitolod, and pegagan had
efficacy as anticancer.
ANOVA and Duncan's Test
The statistical test used for the antioxidant
potency were ANOVA and DUNCAN. The
tests were only done at a concentration of 200
ppm for each extract of akuademineral, hot
water, and ethanol extract, which were directly
compared with vitamin E (200 ppm).
ANOVA test of mahkota dewa, temu putih,
sambi/olo, and keladi tikus extract showed
significantly different results. Therefore it was
necessary to do further test using DUNC AN
test to see whether there were differences in
antioxidant potency in aquademineral, hot
water, ethanol extract and vitamin E on each
plant. DUNCAN test showed different results
from each plant extract. This was because the
content of secondary metabolites contained in
extracts were difTerent that the inhibition
power against MDA tonnation was also
different.
CONCLUSION
The extract of mahkota dewa, lemu pUlih,
sambil%, and keJadi likw; had potency as
antioxidants based on their ability to inhibit
the fonnation of MDA. Data results showed
that the smallest inhibition was found in keladi
tikus extract of 24.32% at concentrations of 50
ppm with hot water solvent. While the greatest
inhibition found in /emu pulih extracts at 1000
ppm, namely 86.27% with the same solvent.
ANOVA of extract at a concentration of 200
ppm for aquademineral, hot water, ethanol
extract, and vitamin E showed significantly
different results. DUNCAN statistical test
showed that the antioxidant activity was
different.
