Abstract
Many diseases correlate with antioxidant deficiencies. Garcinia mangostana L rind (GMR) belong to waste product, contains
xanthones which are antioxidant compounds. The aim of this study was to determine antioxidant properties of its ethanolic
extract, hexane, ethylacetate, butanol, and water fractions in DPPH scavengingactivity, level of SOD and total antioxidant (TAS)
compared against α-mangostin. Extract and all of these fractions had high DPPH trapping activity while α-mangostin had low
activity. Level of SOD was highest in GMR water fraction while TAS level was highest in GMR ethylacetate fraction. It was
concluded that GMR products had potential antioxidant properties

1. Introduction
Antioxidant deficiency correlates with many diseases. Lipid peroxidation is induced by oxidative stress and is a
key process in many pathological events. The destruction of membrane lipid caused by unsaturated lipid oxida tion
producing malondialdehyde as breakdown products is mutagenic and carcinogenic1. G.mangostana rind, as waste
product, contains a lot of water soluble antioxidant2. Various kinds of xanthones in G.mangostana rind had been
proven to have strong antioxidant activity included alpha mangostin3. According to Zarena and Udaya Sankar
(2009), antioxidant activity among these rind extracts was different each other deepending on the solvent:
G.mangostana rind extract especially acetone and ethyl acetate extract was effective to inhibit lipid peroxidation
induced by ferrous sulphate-ascorbate system in the linolenic acid medium as lipid phase model system4. Besides

containing antioxidant activities, it has antitumoral, anti-inflamatory, antiallergy, antibacterial, antiviral , and
antifungal activities5,6. According to Palakawong et al. in their study, antioxidant activity of G.mangostana rind
extracted with 50 % ethanol, which IC50 was 5.94 μg/ml, was the strongest compared to its bark and leaves as well7.
The aim of this study was to evaluate the antioxidant properties of G. mangostana L (GMR) rind 96 % and 70 %
ethanolic extract and hexane, ethyl acetate, butanol, and water fraction by measuring DPPH scavenging activity,
SOD activity, and total antioxidant status of these samples
2. Experiments
2.1. Material
Ripe G.mangostana L which had purple colour collected from Subang (West Java), destilated water, 96 % and 70
% ethanol, hexane, ethyl acetate, butanol, methanol solution, DPPH solution (Sigma Aldrich), Cayman’s Superoxide
Dismutase Assay Kit, and Superoxide Dismutase Assay Kit
2.2. Extraction and`fractionation
Mangosteen fruit rind was washed as clean as possible, dried at 37 C, pounded, and macerated using 96% and
70% ethanol, until the filtrate becoming no colour anymore. The filtrate was evaporated until becoming pasta like
extract. Parts of the 96% ethanolic extracts was macerated again using hexane-water mixture in 1:1 ratio until this
filtrate becoming colourless again and then this filtrate was evaporated also becoming hexane fraction. The last
residu was treatedsuch as before consecutively using ethyl acetate-water mixture 1:1, butanol-water mixture 1:1, and
water only to get ethyl acetate fraction, butanol fraction, and water fraction.
2.3. DPPH scavenging activity assay
The DPPH assay was carried out as described by Unlu et al.8. To obtain the IC50 value, 50 μL of each extract and
fractions of GMR at a range of various final concentrations 100; 50; 25; 12.5; 6.25; 3.125; 1.563; 0.781; 0.391 and
0.195 μg/mL in methanol solution were pippeted and put into the microplate and then added with 200 μL of 0.077
mmol/L DPPH (Sigma Aldrich) in methanol.The reaction mixtures were shaken vigorously and kept in the dark for
30 minutes at room temperature, furthermore DPPH scavenging activity was determined by microplate reader at 517
nm.
The radical scavenging activity of each sample was determined by the ratio of DPPH absorption decrease against
the absorption of DPPH solution in the absence of test sample (negative control) using the following equation.
AS: absorbance of samples, AC: negative control absorbance (without sample)
2.4. Superoxide Dismutase (SOD) activity assay
The SOD assay was carried out using Cayman’s Superoxide Dismutase Assay Kit. 10 μL of three series of
concentrations including 500; 125; 31.25 μg/mL of GMRextract and fractions were pippeted into sample wells, then
200 μL diluted radical detector was added into each wells. For SOD standard wells, 200 μL diluted radical detector
and 10 μL standard was pippeted into the wells (tubes A-G). To intitiate the reactions, 20 μL diluted xanthine
oxidase was added into each wells. This well plate was shaked for few seconds for mixing and incubated on shaker
for 20 minutes at room temperature. Absorbance of each well was read at 450 nm curve and linearized rate (LR).
The SOD level in U/ mL was determinate by the equation below.

2.5. Total Antioxidant Status (TAS) assay
The TAS assay was carried out using Cayman’s Antioxidant Assay Kit. Into the each of the sample wells, 10 μL
of three series of concentrations including 500; 125; 31.25 μg/mL of GMRextract and fractions, 10 μL
metmyoglobin, and 150 μL chromogen were added. For Trolox standard wells, 10 μL trolox standard (tubes A-G),
metmyoglobin, and 150 μL chromogen were put. To intitiate the reactions, 40 μL hydrogen peroxide was added into
all wells. The plate was incubated on a shaker for 5 minutes at room temperature. Absorbance was read at 750 nm
using Elisa Reader. The TAS was calculated using the linear regression equation of the standard curve written in the
following equation3.

3. Results and Discussion
To assure the quality of this crude drugs, proximate analysis was done as shown in Table 1 below.
Table 1. Proximate Analysis of G.mangostanaL Rind Crude Drug
Because of water content of this simplicia is only 10,31 %, this material is dry enough to protect from fungus
contamination. DPPH scavenging activity of GMR extract and its various fractions and alpha mangostin is shown in
the Figure1.

IC50 of DPPH scavenging activity of GMR96% and 70 % ethanolic extracts were (7,48 ± 0,19)% and (6.563 ±
0.311)%. These IC50 is higher, that’s meant less DPPH scavenging activity, than reported by Palakawong et al.7
which was 5.94 μg/mL although they used 50% ethanol for the extraction. The different region of G.mangostana L
collection and degree of the fruit ripeness might play a role to cause it.
Similar results were concluded about different antioxidant activity in using various extraction solution for sample
extraction by Zarena and Udaya Sankar4. This difference could be caused by different extraction capacity of each
solution to extract GMR polar active compund4. Phenolic compound content of GMR extract such as tannin, alpha
mangostin, epicatechin was different if solvent extraction was different. Therefore DPPH and hydroxyl radical
scavenging and also lipid peroxidation inhibition activity was different in several extraction solution.Water extract
had stronger capacity than methanol extract whilemethanol extract had stronger capacitythan hexane extract9. Our
study had the similar results with that ones.
Total antioxidant status/ total antioxidant capacity (mM Trolox) of these GMR extracts, fractions, and alpha
mangostin is shown in Figure 2.
Fig. 2. Total Antioxidant Status (Total Antioxidant Capacity) of GMR (G.mangostana L rind 96 % ethanolic extract), Fractions, Alpha
Mangostin (p < 0,05). GMRE =, *= means significant difference between these groups.
At the same concentration, 500 μg/ mL, TAS of ethyl acetate fraction was the highest among other materials,
followed by alpha mangostin. GMR extract showed same TAS as hexane fraction and water fraction as well, while
butanol fraction showed the lowest (p < 0,05).
SOD activity of GMR 96% ethanolic extract, hexane, ethyl acetate, butanol, and water fraction is shown in the
following figure.

between each group. (p< 0,05)
At concentration 500 μg/ mL,comparing to other materials, GMR extract and also water fraction had the strongest
DPPH scavenging activity, in contrast against alpha mangostin which had the lowest DPPH scavenging activity. But
alpha mangostin had higher TAS than GMR extract (p< 0,05), it may be caused by other antioxidant mechanism of
alpha mangostin besides free radical scavenging such as other enzymatic mechanism besides SOD. GMR extract and
water fraction had same TAS and DPPH scavenging activity although water fraction, also butanol fraction, had the
most SOD activity (p< 0,05). Other antioxidants beside SOD activity could play more role in GMRextract. Although
butanol fraction had the strongest SOD activity, lack of other antioxidant properties might cause its lowest TAS.
Ethyl acetate fraction had the highest TAS even though in lower concentration i.e. 125 μg/mL comparing to other
samples (p< 0,05).
4. Conclusion
In clonclusion,Garcinia mangostana L rind products had potential antioxidant properties.
