ABSTRACT
The research aims to �know the effectiveness of grape seeds in
lowering blood sugar levels in white rats. The research began with grape seed
extraction using the maceration method. The results of macerate were given to
white rats that were given grape seed extract samples at doses of 75 mg/200
grams BW, 125 mg/200 grams BW, and 250 mg/200 grams BW. The positive control
was metformin, and the negative control was given distilled water. All were
given treatment for 14 days. On days seven and 14, a blood sugar test was
carried out to assess the effectiveness of grape seed extract. The results
showed that of the five treatment groups, sample group I (extract at a dose of
75 mg/200 gram BW) and sample group III (extract at a dose of 250 mg/200 gram
BW) affected reducing blood sugar levels in rats. This is proven by comparing
blood sugar levels after being given alloxan on the seventh day in the two
groups, showing better results in reducing blood sugar levels than the other
groups. It can be concluded that grape seed extract can properly reduce blood
sugar levels in white rats with type II diabetes mellitus.

INTRODUCTION
The World Health
Organization (WHO) explains that diabetes cases globally reached 415 million
people in 2015. It has been predicted that in the next 30 years, the number of
diabetes cases will increase significantly to reach 641 million people (Dankoly
et al., 2023). According to WHO, type II diabetes
mellitus is a chronic disease where the pancreas cannot produce enough insulin
to regulate blood sugar levels or when the human body cannot use the insulin
produced by the pancreas effectively. Glucose in the blood will result in
uncontrollability. Damage will occur to certain body organs, such as the heart,
kidneys, eyes, and nervous system (Galicia-Garcia
et al., 2020; Prolanis et al., 2022 ).
In Indonesia itself, type
II diabetes mellitus has succeeded in occupying the top five positions among
the diseases most commonly suffered in Indonesia. In 2019, the IDF
(International et al.) explained that Indonesia was in sixth position in the world,
with an age range between 20-79 years, and had 10.3 million cases of people
living with diabetes (Mulmuliana
1, 2022). According to Riskesdas, in 2013,
East Java Province contributed 2.5% of cases of people suffering from type II
diabetes mellitus. Cities in East Java that contribute the largest number of
people suffering from diabetes mellitus include the cities of Surabaya, Malang,
Lamongan, and Bangkalan (Tsalissavrina
et al., 2018). A plant that has an important role
as a solution in preventing type II diabetes mellitus is grapes.
It is believed that the
ingredients in grapes can be used as an antidiabetic drug. The ingredients that
have an important role in preventing diabetes are flavonoids. This content is
generally found in vegetables, fruit, and plant stems (Clara
et al. et al., 2017; Arifin
& Ibrahim, 2018; Khoirunnisa
& Sumiwi, 2019; Azzahra
et al., 2022; Kamilia
et al. et al., 2022; Nofianti
et al., 2022). Grape seeds also have similar
contents in their fruit and leaves but are rarely used in daily life and are
often thrown away by local people. This research hopes that not only grape
leaves and fruit can be used as medicine to treat type II DM, but grape seeds
are also expected to control blood sugar levels because the flavonoid content
of the seeds also comes from the plant itself. It is hoped that grape seeds can
overcome type II DM as effectively as grapefruit and leaves (Rahman
et al., 2022).
Previous research has identified the
prevalence of diabetes globally, specifically focusing on diabetes, as a
significant public health concern (Ting et al., 2016). Diabetes has a serious impact on the organs of the
body and can cause damage to the heart, kidneys, eyes, and nervous system (Jwad & AL-Fatlawi, 2022). At the national level, Indonesia has a high
incidence rate of diabetes, with Indonesia ranked sixth in the world with the
number of diabetes cases reaching 10.3 million in 2019.
Although previous studies have
revealed antidiabetic potential in other parts of the
vine, such as leaves and fruit, research on grape seeds has been less
exploratory. This gap drives the need for more in-depth research to understand
the extent to which grape seeds can be an effective solution to diabetes.
This study aims to critically
evaluate the extent to which grape seed extract can effectively address
diabetes symptoms in male white rats of the Wistar
strain, provide deeper insight into its inner workings and potential as an antidiabetic drug, and is expected to contribute to the
development of antidiabetic therapies and provide
scientific evidence that can support the use of grape seed extract in clinical
applications in humans.
METHOD
This
research uses a true experimental design using the Pre-Post Test Control Group
Design method. The population used _ in the study is a mouse white
strain wistar, And the
sample is a mouse white male, two months old. The subject study will be shared
into five groups, including control positive (Subject given alloxan
and drug antidiabetic), control negative (Subject
given alloxan and distilled water ), three groups of
samples, respectively given alloxan And extract seed
wine purple the dose consists from 75 mg/200gram BW, 125 mg/200gram BW, and 250
mg/200gram BW and given orally.
RESULTS AND DISCUSSION
The results
of blood sugar levels in all treatment groups, both before being given alloxan
and on the 14th day, have been compiled in the form of the following table.

Information: ∆ Blood Sugar Levels = the difference in blood sugar
levels after administering alloxan on the 7th or 14th day. (+) indicates
∆ that blood sugar has decreased. (-) indicates ∆ that blood sugar
has increased.
Table 1explains explains the
control group and samples that had blood sugar levels tested. The treatment
group before the mice were given alloxan, and the results showed that the blood
sugar levels in each group of mice were ≤ 100 mg/dL. This shows that all
treatment groups, both the control group and the sample group, did not
experience type II diabetes mellitus (Langerman et al., 2022).
Based on data on blood sugar
levels after being given alloxan, the results showed that blood sugar levels in
each group of mice were ≥ 100 mg/dL. This shows that all treatment
groups, both the control group and the sample group, experienced hyperglycemia
(Type II Diabetes Mellitus).
Based on data on blood sugar
levels on the seventh day after being given alloxan. The results showed that
blood sugar levels in each group of mice experienced changes (Cai et al., 2023). Some experienced a decrease,
and some even experienced an increase even though they had been given treatment
to reduce blood sugar levels (Deora & Venkatraman, 2022). In the positive control,
four mice experienced an increase when their blood sugar levels were tested on
the seventh day. Then, for sample III, four mice experienced a decrease in
blood sugar levels after being tested for blood sugar levels on day seven and
compared with blood sugar levels after the treatment group was given alloxan (Atiya et al., 2022).
This shows that during
treatment, each treatment group experienced changes in blood sugar levels,
especially in the grape seed extract solution. Because on day 7, most of the
sample group experienced a decrease in blood sugar levels compared to those
after being given alloxan. Based on data
on blood sugar levels on the 14th day after being given alloxan . The results
showed that blood sugar levels in each group of mice changed. When compared
with the results of blood sugar levels on day 7, the results of blood sugar
levels on day 14 were much better. Sample Group 3 provided the effect of
reducing high blood sugar levels. The negative control group did not have the
effect of reducing blood sugar levels. However, it increased the blood sugar
levels of mice in the negative control group (Daniell et al., 2023).
Based on the table 1, ∆ blood sugar levels compare the
difference in blood sugar levels. Moreover, the table explains that on the 14th
day, it had a significant impact, namely that blood sugar levels experienced a significant
decrease in blood sugar levels after being given alloxan to the group of mice.
However, on the 7th day, the results were not much different on the 14th day.
The research began by drying
the grape seeds before extraction. Grape seed samples are dried because if the
grape seeds are still wet, the sample will grow fungus, which can cause the
contents of the grape seeds to become unstable and also to avoid rotting that
occurs in fungi. Samples that have been dried are ground using a blender. The purpose
of grinding is to make it easier for the sample to dissolve in the solvent used
in making grape seed extract and to obtain a higher yield than samples that are
not ground (Da Porto et al., 2013). The samples were extracted
using the maceration method for 3x24 hours, and maceration was carried out two
times. Samples that have been macerated will be thickened using a rotary evaporator. After the water
content in the sample begins to decrease, the sample is thickened using a water
bath for thickening. The reason for moving the thickening process is that when
the sample in the rotary evaporator starts
to thicken, and the water content of the sample starts to decrease, the sample
will be difficult to remove. The sample will be left in the round flask
container used in the rotary evaporator.
Samples that have been thickened are stored in an airtight and
watertight room to prevent the samples from growing mold or other pathogens
that affect the contents of the grape seed samples.
Based on the data in the
table, it shows the blood sugar levels in the control group and sample group
before being given alloxan. The results showed that the blood sugar levels of
mice in all treatment groups, both control and sample groups, were ≤ 100
mg/dL. From this table, it can be explained that the mice in the control and
sample groups were still in normal condition, and the mice had not experienced
type II diabetes mellitus.
Based on the data in the
table, it shows the blood sugar levels in the control group and sample group
after being given alloxan. The results showed that blood sugar levels in the
control and sample groups after being given alloxan were ≥ 100mg/dL. This
can explain why both the control group and the control sample experienced
diabetes mellitus II. This is reinforced by the mechanism of alloxan, which can
damage cells contained in insulin, where insulin can control blood sugar in the
body (Gargouri et al., 2016).
Based on the data in the
table, it shows the blood sugar levels in the control group and sample group on
the seventh day after being given alloxan. The results showed that blood sugar
levels in the control group and sample group experienced changes when compared
with blood sugar levels after administering alloxan. This is indicated by the
increase in blood sugar levels in the positive and negative control groups. The
reason blood sugar levels in the positive control group increased was that the
dose of metformin in this study could not have an effect in reducing blood
sugar levels in mice. The second reason is that each white rat has a different
metabolism in receiving metformin solution into the white rat's digestive
system, so there are mice whose blood sugar levels decrease. There are mice
whose blood sugar levels increase. Most of the sample group experienced a
decrease in blood sugar levels. For sample groups 1 to 3, blood sugar levels in
these sample groups mostly experienced a decrease in blood sugar levels
compared to sugar levels after administering alloxan with blood sugar levels on
the 14th day. Among the three sample groups, those that had good effectiveness
in lowering blood sugar levels were sample group 1 and sample group 3. This was
because grape seed extract samples given orally to white mice could lower blood
sugar levels in white mice compared to those with lower blood sugar levels.
High blood pressure decreased simultaneously with the extract treatment for 14
days. This is reinforced by grape seed extract containing flavonoids, which
have a mechanism for stimulating insulin to release pancreatic beta cells and
flow into the blood. Besides stimulating insulin, flavonoids can also improve
or restore insulin sensitivity in cells (Chan et al., 2019). Sample group 2 showed good
data regarding the ability of grape seed extract samples to lower blood sugar.
However, some mice showed that during treatment, both on day seven and day 14,
when blood sugar tests were carried out, they did not show a decrease in blood sugar
levels.
Based
on the data in the table, it shows the blood sugar levels in the treatment
group, both the control group and the sample group, on the 14th day after being
given alloxan. The results showed that blood sugar levels in the control group
and sample group experienced changes when compared with blood sugar levels
after administering alloxan. This is proven by the positive control group's
blood sugar levels still increasing and the sample group experiencing a
decrease in blood sugar levels. Among the three sample groups, those that had
high effectiveness in reducing blood sugar levels on the 14th day were sample
group 1 and sample group 3.
CONCLUSION
as an antidiabetic drug
in Wistar strain white rats. It can be concluded that this research shows that grape seed
extract is effective in lowering blood sugar levels in Wistar strain white
rats. This is indicated by blood sugar levels on day seven and day 14, showing
a decrease in blood sugar levels. The dose of grape seed extract that
effectively reduces blood sugar levels is a dose of 75 mg/200 gramsBB (Sample
I) and 250 mg/200 gramsBB (Sample III). This is shown in sample group I; the
average blood sugar levels on days seven and 14 were 113 mg/dL and 144 mg/dL.
Sample group II with average blood sugar levels on days seven and 14 were 161.4
mg/dL and 188 mg/dL. Sample group III average blood sugar levels on days seven
and 14 were 201.8 mg/dL and 185.6 mg/dL. The three sample groups showed a good
reduction in blood sugar levels compared to the positive and negative control
groups.
