Abstract: Rose (rosa canina) is one of the flowers that are much in demand by the community because besides being an
ornamental flower it can also be used as a cosmetic base material. Rose also contains a variety of substances
that are treated as antioxidants, and free radical scavenging. The antioxidant activity test in this study used
the parameters of diphenyl picrylhydrazin (DPPH) trapping activity and tyrosinase enzyme inhibition. Rose
petals and base of rose contain flavonoids, phenols, tannins, triterpenoids, and alkaloids. At the same
concentration of sample between the petals and the base of the rose produces different DPPH trapping
activities, where the DPPH trapping activity on the rose petals was stronger than the base of the rose. IC

value of rose petals <50 μg / ml while the base of rose > 50 μg / ml. It was seen that the effect of increasing
tyrosinase inhibition was due to an increase in the concentration of the group extract and base of rose flowers,
and the results were that at a concentration of 100 µg / ml there was a peak anti-tyrosinase activity.
1 INTRODUCTION
The characteristics of decreased beauty due to aging
of the skin in humans are rough, dull skin surface, the
appearance of brown spots, the appearance of skin
wrinkles, weak skin flexibility which must occur in
all human beings (Widowati, et.al., 2016). Excessive
exposure to ultraviolet (UV) light increases the
contribution of free radicals known as Reactive
Oxygen Specices (ROS). This certainly affects the
process of melanogenesis in the skin catalyzed by the
enzyme tyrosinase. This enzyme regulates skin
pigmentation through melamine synthesis. Increased
UV radiation will increase melanin synthesis, which
causes the risk of pigmentation or melanoma
disorders (Lai, Wichers, Soler-Lopez & Dijkstra,
2018).
Bioactive compounds that exist in plants such as
isoflavones, anthocyanins, and katesin have strong
antioxidant activity against free radicals called
neutralizing excessive Reactive Oxygen Species
(ROS). The body has enzymatic and non-enzymatic
antioxidant defense systems. The antioxidant
enzymes are superoxide dismutase, catalase, and
glutathione peroxidase. While non-enzymatic
antioxidants are glutathione, tocopherol (Vitamin E),
Vitamin C, b-carotein and selenium (Shalaby and
Shanab, 2013; Ismail et al, 2020). Lately antioxidants
have become something of interest in the medical
world, known to have an effect on preventing
premature aging (anti-aging) against free radicals
(Garg, Khurana & Garg, 2017).
Rose plant (Rosa canina) contains vitamins (B, P,
PP, E, K, and C), flavonoids, carotene, carbohydrates,
and organic acids which most of these substances
have properties as anti-oxidant, anti-inflammatory,
free radical scavenging inhibits the oxidation process
(Masek, Latos, Chrzescijanska & Zaborski, 2017).
Flavonoid acid as an antioxidant and anti-tyrosinase
is very beneficial against skin pigmentation (Zuo,
et.al., 2018). Tyrosinase or polyphenol oxidase is an
oxidireductase that plays a role in melanin
biosynthesis and is the main pigment in hair, eyes and
skin. The reaction of the tyrosinase enzyme with the
L-DOPA substrate can produce an orange color.
Inhibition of the activity of the tyrosinase enzyme is
characterized by a reduction in the orange color that
is formed or the result of a color reaction becoming
more clear while simultaneously marking the
occurrence of antioxidant activity (Fais, et al., 2009).
The tyrosinase enzyme is an enzyme responsible
for skin darkening or melanogenesis. Tyrosinase in
humans is a complex protein and is precisely folded,
expressed and undergone post-translational
modifications including Heavy glycolysation

(Zolghadri, et al., 2019). Diphenyl picrylhydrazin
(DPPH) compound is a free radical that is stable in
aqueous or methanol solution and has a purple color
(indicated by the absorption band in the methanol
solvent at a wavelength of 515-520 nm). The DPPH
has properties that are sensitive to light, oxygen, and
pH, but are stable in the form of radicals so that it is
possible to measure an accurate antioxidant activity.
The antioxidant compounds will release hydrogen
atoms to form radical antioxidant compounds. The
DPPH which is a free radical that reacted with
antioxidant compounds to form non-radical DPPH
(Widowati, et.al., 2016). Mini rose showed the
greater antioxidant activity in the ferric reducing
antioxidant power (FRAP) and DPPH tests before
digestion in vitro and together with cosmos as a
source of phenolics with good antioxidant activity (de
Morais, et.al., 2020). Dry rose tea can be used as a
functional food to be a source of natural antioxidants
(Kart & Çağındı, 2017).
Previous studies have shown that phytochemical
compounds contained in Rosa Damascena flower
petals consist of alkaloids, flavonoids, tannins,
carbohydrates, and amino acids (Tatke, Satyapal,
Mahajan & Naharwar, 2015). It has also been found
that rose petal extract contains high anthocyanins,
flavonoids, polyphenols (Lee, et.al., 2018). Unlike
the results of the phytochemical tests in this study,
where the rose petals also contain triterpenoids and
terpenoids.
Measuring the effectiveness of a compound in
biological or biochemical functions capable of
inhibiting the oxidation process by 50% (IC
50
) was
classified in several groups including <50 µg µg per
milliliter (very strong); 50-100 µg µg per milliliter
(strong); 101-150 µg µg per milliliter (moderate); >
150 µg µg per milliliter (weak) (Budaraga, Marlida &
Bulanin, 2016). The IC
50
value of extracted by DPPH
method on black soybean and daidzein was 116.52 µg
/ mL and 109.34 µg / mL, repectively, which means
it has moderate antioxidant strength (Kuswanto,
2018). Ethanol extract of cocoa beans and kojat acid
can be used as inhibitors of enzymaticrosinase
(Kurniasari, Djajadisastra & Anwar, 2018). Oil
obtained from Nigela Sativa seeds (known as black
cumin) is also often used as an anti-oxidant and anti-
inflammatory (Bordoni, et.al., 2019). Manga waste
(skin, seed coat, seeds) from the Colombian manga
cultivar is a source of phenolic compounds that can
be used as antioxidants and free radical cleaners
(Castro-Vargas et al., 2019).
The antioxidant activity test of Rosa damascena
rose petal extract was using standard ascorbic acid
(iron reducing power test) and showed the highest
antioxidant in the cream formula (Safia, et.al., 2019).
The results show that rose extract has good potential
for cosmetic development. Rose oil has the strongest
antioxidant effect and a mixture of Rose oil, bergamot
and patchouli (RBP) with a volume ratio of 7: 2: 1
produces the strongest antioxidant effect on the
DPPH and ATBS Test [2,2-azinobis (3-
ethylbenzothiazoline-6 sulphonic acid)]
(Wongsukkasem, e.al., 2018). In that study also found
that rose oil and bergamot have an antityrosinase
activity around 28 ± 14.2% and 21 ± 10.7%.
However, the study did not specifically explain
whether there were differences in antioxidant
concentrations between the base and rose petals.
2 METHOD
This research is an experimental laboratory study
with data collection (random sampling) using
samples of rose extract and receptacle. The study was
conducted from July-September 2019 at the
Biomolecular Laboratory and Biomedical Research
Center (Aretha Medika Utama). The sample used was
a rose obtained from the Source Seed Management
Unit, Research Institute for Miscellaneous Plant
Flowers in Malang and has gone through a process of
determination. Rose was washed and dried in the sun
to dry milled and extracted by maceration technique
using 70% ethanol solvent for 3 days at room
temperature. Next, the marinade was filtered to
separate the filtrate and the residue. The obtained
filtrate was evaporated with
amotor unit that rotates
the evaporation flask in 50
celcius degrees, so that a
solid extract was received.
Rose petals has 1400 g net weight, simplicia
powder of rose petals was 250 grams and the basic
wet weight of rose flower was 700 g processed into
simplicia powder, base of rose flowers about 90
grams each dissolved in 70% ethanol for 3 days by
maceration method, so the extract of rose petal about
88.56 and 2.72 grams of rose base extract.
The tools and materials used in the
phytochemical, DPPH trapping, and tyrosinase tests,
respectively, are given in Table 1. Phytochemical
tests are used to identify phenol compounds, steroids
/ triterpenoids, saponins, tannins, terpenoids,
flavonoids, and alkaloids found in the lids, and bases
roses.
Identification of phenol was carried out by
dissolving extracts of petals and rose base 10 mg in
ddH2O about 5 ml then adding 500% FeCl
3
solution
about 500 µl. It is known that the sample solution
contains phenol group compounds if one of the
HIMBEP 2020 - International Conference on Health Informatics, Medical, Biological Engineering, and Pharmaceutical
18
primary colors is red or blue or the secondary colors
are green, purple, or black.
The process of identifying steroids / triterpenoids
was done by dissolving 10 mg into a drip plate,
adding glacial acetic acid until submerged for 10-15
minutes, then adding one drop of concentrated
H
2
SO
4
. If the solution produces blue green, this
portion of the population contents the more chemical
elements of the steroid class. Whereas if the solusion
produces purple / red / orange color, this portion of
the population contents the more chemical elements
of the triterpenoid group.

Identification of saponins in the sample is the
presence of foam which is always stable, after going
through the process of dissolving 10 mg of petals and
rose flower base extract using ddH2O in a heat-
resistant glass container, heated to boiling for 5
minutes, filtered, stirred vigorously and the addition
of 1 N hydrogen chloride solution. The identification
of tannins can be done by entering a 10 mg sample
into a heat-resistant glass container containing 2 N
hydrochloric acid with a volume of 2ml. Heating is
carried out in a water medium which lasts for half an
hour. After that, add the type of alcohol pentanol
(C
5
H
11
OH) with a volume of 500 µl. The pentanol
layer will produce a tannin group compound if one of
the layers is orange or red.
Terpenoids are identified by entering a 10 mg
sample into a drip plate, adding vanillin to taste,
adding concentrated H

to one drop and then
homogenizing, if it produces a purple color then the
sample contains compounds of terpenoid class.
Identification of flavonoids was carried out by
dissolving a sample of 10 mg of petal extract and rose
flower base in a test tube containing 2 N hydrogen
chloride. Add sufficient magnesium or zinc, then heat
for 5-10 minutes, cool and filter. After that, add
pentanol with a volume of 1 ml. Extract samples and
rose petals will produce flavonoid class compounds if
the sample gives either red or orange color.
Identification of alkaloids by dissolving samples
of rose petals and base extracts in 5 ml ddH2O
evaporated in a water bath. After producing a
precipitate, immediately add 5 milliliters of 2N
hydrochloric acid. The resulting solution is divided
into 2 test tubes. The first tube is called a comparator
by inserting 3 drops of 2N HCl. While the second tube
solution is transferred as much as one drop to the drop
plate, then give 3 drops of Dragendorff reagent.
Identify alkaloids (+) if they form an orange
precipitate.
A total of 200 µL DPPH 0.077 mmol in methanol
was added with a rose sample extract and 50 µL
receptacle each on the microplate. The mixture was
incubated at room temperature for 30 minutes to
obtain the absorbance value at a wavelength of 517
nm using a microplate reader. For negative control,
250 mL DPPH was used, while for blanks, 250 mL
absolute DMSO was used (Widowati, et.al., 2016).

Zulghadar described that the method of inhibiting
tyrosinase enzyme activity was carried out with minor
changes (Zolghadri, et.al., 2019). A mixture of
aqueous solution consisting of 20 µL samples of rose
extract and receptacles (concentration 100 µg / mL;
50 µg / mL; 25 µg / mL; 12.50 µg / mL; 6.25 µg / mL;
3.13 µg / mL ), 20 µL of the Tyrosinase from

potassium phosphate buffer (20 mM, pH 6.8) were
incubated at room temperature during a quarter of an
hour. Besides that, it was also prepared for controls
containing only 20 µL enzymes and 160 µL
phosphate buffer and blanks which only contained
160 µL phosphate buffer and 20 µL samples. Further,
the solution mixture was added as much as 20 µL of
L-DOPA substrate (1.5 mM) and re-incubated at
room temperature for 10 minutes. Absorbance was
measured using a wavelength of 470 nm. The
percentage of inhibitory activity was calculated using
the following formula:
% inhibition =

 100
(2)
where C is the enzyme absorbance activity without a
sample, and S is the enzyme absorbance activity by
the addition of the tested sample.
The obtained data the experiment was processed
using the SPSS program with the One-Way ANOVA
test and continued by the Post Hoc Test using the
Tukey HSD test with a confidence level of 95% (α =
0.05). The DPPH and anti-tyrosinase activity test
results were followed by an analysis of the linear
regression equation to determine the value of
Inhibition Concentration 50 (IC
50
). Overall, the
stages of the rose extraction process can be seen in
Figure 1.

3 RESULTS AND DISCUSSION
It was found that phytochemical screening for rose
petals and base of rose contained flavonoids, phenols,
tannins, triterpenoids and alkaloids, without saponins.
Rose petals contain terpenoids but not for base of the
rose. Antioxidant activity by trapping DPPH in rose
petal extract was always higher than rose base extract
at various concentrations. This result can be seen in
Table 2, where the data is presented in the form of an
average ± standard deviation. The difference in the
percentage of DPPH and anti-tyrosinase trapping
activity at each concentration (expressed in µg / ml)
indicates that F count> F table with p <0.001 =
0.05. The total antioxidant activity of rose petals and
base of rose extracts will increase with the increase of
theconcentration. At the maximum concentration,
rose extract showed the highest antioxidant activity.

Antioxidant activity by trapping DPPH in rose
petal extract is higher than base of rose extract. This
can be seen in Table 4 where the average IC
50
value
of rose petal extract was 14.89 µg / mL; while in the
basic extracts of roses, the average IC
50
value was
52.81 µg / mL. In the anti-tyrosinase (A-TS) activity
test on base of rose, it is more effective than rose
petals, it can be seen that IC
50
values are 62.27 μg /
mL and 58.66 μg / mL for rose petals and base of rose,
reapectively.

4 CONCLUSION
Comparison of antioxidant activity through DPPH
trapping based on IC
50
value of rose petal extract has
a value of 14.89 μg / ml and rose base extract has
52.81 μg / ml. This shows that the rose petals are
stronger than the base of the rose. The IC
50
value of
the antitirosinase test results on rose petal extract and
rose base have antitirosinase activity of 62.27 μg / ml
and 58.66 μg / ml, respectively. These results indicate
that the base of the rose is more effective than rose
petals
