Phytochemical and Antibacterial Screening Tests from the Ethanol Extract of the Ceremai Leaf Against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli

Introduction

The increasing prevalence of antibiotic-resistant bacteria has led to a growing interest in the discovery of new antibacterial agents from natural sources. One such source is the Ceremai leaf (Phyllanthus acidus (L) Skeels), a plant that has been traditionally used in various cultures for its medicinal properties. This study aims to evaluate the potential of phytochemicals and antibacterial activity of the ethanol extract of the Ceremai leaf against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli.

Materials and Methods

The extraction process of the Ceremai leaf was carried out using the maceration method, where the leaf powder was soaked in 96% ethanol solvent for 48 hours. After this process, the extract was processed using a rotary evaporator to get a concentrated extract that is ready to be tested.

Phytochemical Screening Test Results

The results of the phytochemical screening test showed that the ethanol extract of Ceremai leaves contain active compounds, namely saponins and tannins. Saponins are known to have various benefits, including as an antibacterial and antifungal agent. Meanwhile, tannins can have an astringent effect and function as antioxidants. The existence of these compounds is an indication that Ceremai leaves have the potential as a source of natural ingredients that can be used in treatment.

Antibacterial Activity Test

The antibacterial activity test was performed to assess the effectiveness of the ethanol extract of Ceremai leaves against pathogenic bacteria, namely Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. The test results show that the extract at a concentration of 20% gives a significant inhibitory zone diameter, which is 10.05 mm for Staphylococcus epidermidis and Staphylococcus aureus, and 9.00 mm for Escherichia coli.

Analysis of Results

The diameter of the inhibition zone produced shows that the extract of Ceremai leaf has the potential as an effective antibacterial agent. This can be utilized in the development of safer and natural herbal medicinal products compared to synthetic antibiotics. Given the increase in bacterial resistance to antibiotics, the discovery of antibacterial compounds from natural sources is very important in the world of health.

Discussion

The results of this study suggest that the ethanol extract of Ceremai leaves has potential as an antibacterial agent against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. The presence of saponins and tannins in the extract is a strong indication of its potential as a natural antibacterial agent. The inhibitory zone diameter produced by the extract is significant, indicating its effectiveness against these pathogenic bacteria.

Conclusion

Overall, this study provides insight into the potential of Ceremai leaf ethanol extract in the pharmaceutical field, especially as a natural antibacterial. Further studies are needed to identify active compounds and the mechanism of action of this extract, so that it can be developed into a product that is useful in the treatment of bacterial infections. With the right attention, Ceremai leaf extract can be a promising alternative in antibacterial therapy.

Future Directions

Future studies should focus on identifying the active compounds responsible for the antibacterial activity of Ceremai leaf extract. Additionally, the mechanism of action of this extract should be investigated to understand how it interacts with bacterial cells. This knowledge will be essential in developing a product that is safe and effective for use in humans.

Limitations

This study has several limitations. Firstly, the sample size was small, and further studies should be conducted to confirm the results. Secondly, the study only tested the antibacterial activity of Ceremai leaf extract against three pathogenic bacteria, and further studies should be conducted to test its activity against other bacteria. Finally, the study did not investigate the toxicity of Ceremai leaf extract, and further studies should be conducted to determine its safety for use in humans.

Conclusion

In conclusion, this study provides insight into the potential of Ceremai leaf ethanol extract as a natural antibacterial agent. The results suggest that the extract has potential as an effective antibacterial agent against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. Further studies are needed to identify active compounds and the mechanism of action of this extract, so that it can be developed into a product that is useful in the treatment of bacterial infections. With the right attention, Ceremai leaf extract can be a promising alternative in antibacterial therapy.
