Unlocking the Antioxidant Potential of Jackfruit Leaves: A Study on the Ethanol Extract's Activity using the DPPH Method

Introduction

In recent years, the world has witnessed a growing interest in natural antioxidants, which are compounds that can neutralize free radicals and prevent oxidative stress. Among the various sources of natural antioxidants, plants from the Moraceae family have been widely recognized for their potential health benefits. One such plant is the jackfruit tree (Artocarpus heterophyllus), which is native to tropical regions and has been used for centuries in traditional medicine. The leaves of the jackfruit tree are rich in secondary metabolites, which are compounds that have significant biological potential, including antioxidant activity. This study aims to investigate the antioxidant activity of jackfruit leaf ethanol extract using the DPPH method, a widely accepted technique for assessing the potential of antioxidants.

Background

Free radicals are unstable molecules that can cause oxidative stress and damage to cells, leading to various degenerative diseases, including cancer and heart disease. Antioxidants, on the other hand, are compounds that can neutralize free radicals and prevent oxidative stress. Plants from the Moraceae family, including the jackfruit tree, have been found to contain various secondary metabolites that have antioxidant activity. These compounds are produced by plants in smaller amounts but have significant biological potential. The antioxidant activity of these compounds is essential in protecting the body's cells from damage caused by free radicals.

The Importance of Antioxidant Activity Testing

Antioxidant activity testing is a crucial step in evaluating the potential of natural antioxidants. The DPPH method is a widely accepted technique for assessing the antioxidant activity of compounds. This method involves the use of DPPH solutions, which are purple. When antioxidants from jackfruit leaf extract are added, DPPH radicals will be reduced, and the color changes from purple to yellow can be measured. The results of this measurement provide information about how effective the extract is in reducing free radicals.

Methodology

In this study, the antioxidant activity of jackfruit leaf ethanol extract was tested using the DPPH method. The extract was prepared by dissolving the dried leaves in ethanol, and the resulting solution was then added to DPPH solutions. The reaction was monitored, and the color change was measured using a spectrophotometer. The results were then analyzed to determine the IC50 value, which is the concentration needed to reduce DPPH activity by 50%.

Results

The test results showed that jackfruit leaf ethanol extract has antioxidant activity with an IC50 value of 57,1552 µg/ml. The IC50 value is a critical parameter in evaluating the antioxidant activity of compounds. A lower IC50 value indicates that the extract is more effective in reducing free radicals. The regression obtained, namely y = 0.7466x + 7,3279, and the correlation coefficient R² = 0.9779, shows that there is a strong relationship between the concentration of extracts and the ability to reduce free radicals.

Conclusion

The results of this study indicate that jackfruit leaf ethanol extract has strong antioxidant activity. The low IC50 value indicates that this extract is effective in neutralizing free radicals. Therefore, the use of jackfruit leaves as a source of natural antioxidants should be considered further. Further research can be carried out to explore other potentials of this plant and its applications in the health sector, as well as for the development of jackfruit leaf extract products that can support public health.

Implications and Future Directions

This study has significant implications for the use of jackfruit leaves as a source of natural antioxidants. The results of this study suggest that jackfruit leaf ethanol extract can be used as a potential health supplement to prevent oxidative stress and damage to cells. Further research can be carried out to explore the potential of jackfruit leaves in preventing various diseases, including cancer and heart disease. Additionally, the development of jackfruit leaf extract products can provide a new source of income for farmers and communities that cultivate jackfruit trees.

Conclusion

In conclusion, this study has demonstrated the antioxidant activity of jackfruit leaf ethanol extract using the DPPH method. The results of this study indicate that jackfruit leaf ethanol extract has strong antioxidant activity, and the low IC50 value suggests that this extract is effective in neutralizing free radicals. Therefore, the use of jackfruit leaves as a source of natural antioxidants should be considered further. Further research can be carried out to explore other potentials of this plant and its applications in the health sector, as well as for the development of jackfruit leaf extract products that can support public health.
