Antibacterial Activity Test: Ethanol Extract and Chopped Leaf Fraction (Allium schoenophrasum L.) Against Escherichia coli and Staphylococcus aureus Bacteria

Introduction

Kucai (Allium Schoenophrasum L.): A Plant with Multifaceted Properties

Kucai, also known as chives, is a plant that originates from North America and Northern Europe, belonging to the Allliaceae family. This plant has been widely used as a culinary herb, but its potential as a medicinal plant has not been fully explored. In this study, we aim to investigate the antibacterial activity of ethanol extract and chopped leaf fraction of kucai against Escherichia coli and Staphylococcus aureus bacteria.

Methodology

Characterization of Simplicia and Phytochemical Screening

The methodology used in this study includes the characterization of simplicia, phytochemical screening, as well as extraction and fractionation using 96% ethanol solvent, N-Hexane, and ethyl acetate. The characterization of simplicia involves the determination of water content, water-soluble juice levels, ethanol-soluble juice levels, total ash content, and ash content not soluble in acid. Phytochemical screening is used to identify the presence of various groups of active compounds, including alkaloids, flavonoids, glycosides, tannins, saponins, and steroids/triterpenoids.

Extraction and Fractionation

The extraction and fractionation process involves the use of 96% ethanol solvent, N-Hexane, and ethyl acetate to obtain the ethanol extract and chopped leaf fraction. The N-Hexane fraction is expected to contain steroids/triterpenoids, while the ethyl acetate fraction is expected to contain alkaloids, flavonoids, glycosides, tannins, and saponins.

Results

Antibacterial Activity Test

The antibacterial activity test is performed using the diffusion method, where a pertiner paper is used to measure the diameter of the inhibitory zone of bacterial growth. The results show that the ethanol extract with a concentration of 25 mg/ml has the ability to inhibit the growth of both Escherichia coli and Staphylococcus aureus bacteria. The N-Hexane fraction does not show antibacterial activity against Escherichia coli, but effectively inhibits the growth of Staphylococcus aureus at a concentration of 300 mg/ml. The ethyl acetate fraction can inhibit the growth of both bacteria at a concentration of 5 mg/ml, while the remaining fraction can inhibit both at a concentration of 200 mg/ml.

Discussion

Potential of Kucai as an Antibacterial Agent

The results of this study suggest that the ethanol extract and chopped leaf fraction of kucai have the potential as antibacterial agents. This shows that chives are not only useful as food, but also have biological activity that can be utilized in the health sector. The presence of active compounds such as alkaloids, flavonoids, glycosides, tannins, saponins, and steroids/triterpenoids in the kucai plant may contribute to its antibacterial activity.

Implications for the Development of Natural Antibacterial Products

The existence of active compounds with antibacterial potential in the kucai plant provides great opportunities for the development of plant-based products as a solution to the problem of resistant bacteria to conventional antibiotics. Further research is needed to explore the action mechanisms of these compounds and the possibility of its use in the development of natural antibacterial products.

Conclusion

Conclusion and Future Directions

In conclusion, the results of this study suggest that the ethanol extract and chopped leaf fraction of kucai have the potential as antibacterial agents. This study highlights the importance of exploring the multifaceted properties of plants like kucai, which can provide new opportunities for the development of natural antibacterial products. Further research is needed to fully understand the action mechanisms of these compounds and to explore their potential applications in the health sector.
