Extract Antioxidant Activity Test and Jamblang Leaf Fraction (Syzigium cumini L.) with the DPPH Method

Introduction

Jamblang, or Syzygium cumini L., is a traditional medicine that has been widely used for centuries. This plant is rich in active compounds, especially from polyphenol groups that function as a source of natural antioxidants. The aim of this study is to compare the antioxidant activity of ethanol extract, N-Hexan fraction, ethilatate fraction, and residual fractions of jamblang leaves.

Background of Jamblang (Syzygium cumini L.)

Jamblang, or Syzygium cumini L., is a member of the Myrtaceae family that has been widely used as a traditional medicine. This plant is rich in active compounds, especially from polyphenol groups that function as a source of natural antioxidants. The antioxidant activity of jamblang leaves has been reported to be high, making it a potential source of natural antioxidants.

Materials and Methods

In this study, simplicia powder from jamblang leaves is characterized and tested, then extracted using a maceration method with 80% ethanol solvent. Furthermore, jamblang leaf extract is difraxinated using N-Hexan and ethilatate solvents. The antioxidant activity test was carried out using the DPPH method (1,1-difenil-2-picrilhydrazil) where DPPH absorbance was measured using a spectrophotometer at a wavelength of 516 Nm in the 15th minute after the addition of methanol solvents. As a comparison, quercetin is used.

Characterization of Jamblang Leaf Extract

The results of the characterization of simplicia powder and jamblang leaf extract showed the water content of 7.94% and 6.61% respectively. Water soluble levels are recorded at 15.58% and in ethanol 15.92%. In addition, the total ash content is 6.06% for simplicia powder and 4.75% for extracts, while the insoluble ash content is 0.83% and 0.75% respectively.

Phytochemical Analysis

Phytochemical analysis shows that jamblang leaves contain important chemical compounds such as flavonoids, glycosides, tannins, saponins, and triterpenoids/steroids. These compounds are known to have antioxidant activity, making jamblang leaves a potential source of natural antioxidants.

Antioxidant Activity Test

From the analysis of antioxidant activity, ethanol extract has an IC50 value of 13.54 μg/ml, while the ethilatate fraction shows the lower IC50 value of 5.32 μg/ml, followed by the residual fraction with an IC50 value of 14.13 μg/ml, and quercestine with an IC50 value of 4.36 μg/ml. All of these values indicate very strong antioxidant activity, while the N-Heksan fraction has an IC50 value of 53.5 μg/ml which is still classified as strong, but lower than the ethilatate fraction and ethanol extract.

Conclusion

The conclusion of this study shows that the ethilatate fraction has higher antioxidant activity compared to other solvents. These results confirm the importance of jamblang leaves as a potential source of natural antioxidants, which can be utilized in the development of herbal medicines and other health products.

Implication of the Study

This study not only provides information about the potential of jamblang leaves in the health sector, but also adds insight into the importance of further research on other medicinal plants that can provide similar benefits. The results of this study can be used as a reference for further research on the antioxidant activity of jamblang leaves and other medicinal plants.

Future Research Directions

Future research directions include the isolation and characterization of the active compounds responsible for the antioxidant activity of jamblang leaves. Additionally, the study of the antioxidant activity of other medicinal plants that have similar chemical compounds to jamblang leaves can provide valuable information for the development of new herbal medicines and health products.

Conclusion

In conclusion, this study has shown that the ethilatate fraction of jamblang leaves has higher antioxidant activity compared to other solvents. The results of this study confirm the importance of jamblang leaves as a potential source of natural antioxidants, which can be utilized in the development of herbal medicines and other health products.
