Analysis of the Composition of Fatty Acids from Avocados (Persea Americana Mill) with the GC-MS Analysis Method and the Test of Antibacterial Activity

Introduction

Avocados (Persea Americana Mill) are widely recognized for their rich taste and nutritional value, but they also contain potential health benefits, including the seeds that are often overlooked. This study aims to analyze the composition of fatty acids from avocado seeds and evaluate its antibacterial activity using the Chromatography-Mass Spectrometry (GC-MS) gas method.

Materials and Methods

In this study, avocado seeds that have been mashed are extracted using the method of maceration with the N-HEXANE solvent. This extraction process aims to take oil from seeds that are rich in fatty acids. After the oil is obtained, the next step is the esterification process before the analysis using GC-MS. The analysis shows that avocado seeds contain a number of fatty acids, including linoleic acid (25.68%), stearic acid (25.19%), palmitic acid (22.05%), oleic acid (2.52%), palmitoleic acid (1.66%), and behenic acid (1.28%).

Results

The analysis revealed that avocado seeds have a significant proportion of fatty acids. Linoleic acid, which is an essential fatty acid, has an important role in heart health and can help reduce inflammation. Meanwhile, oleic acid is known to have benefits in reducing the risk of heart disease and improving metabolic health.

In addition to the analysis of the composition of fatty acids, this study also assesses the antibacterial activity of avocado seed extract. The test was carried out on several pathogenic bacteria such as E. coli, S. typhi, and S. Aureus with a concentration of 500 mg/ml. The results show that avocado seed extract has significant antibacterial activity, with the inhibition zone of each bacterium is 11.74 mm for E. coli, 12.94 mm for S. typhi, and 13.81 mm for S. Aureus. This shows that avocado seeds not only function as a source of nutrition, but also have the potential as a natural antibacterial agent.

Discussion

The results of this study demonstrate that avocado seeds have a composition of fatty acids that are beneficial for health and also show promising antibacterial activity. The presence of linoleic acid and oleic acid in avocado seeds suggests that they may have a positive impact on heart health and metabolic function. Additionally, the antibacterial activity of avocado seed extract suggests that it may have potential as a natural remedy for infections caused by pathogenic bacteria.

The discovery of the antibacterial activity of avocado seed extract is significant, as it may provide a new avenue for the development of natural antibacterial agents. The use of natural products as antibacterial agents is becoming increasingly popular, as they are often less toxic and more environmentally friendly than synthetic antibiotics.

Conclusion

In conclusion, this study demonstrates that avocado seeds have a composition of fatty acids that are beneficial for health and also show promising antibacterial activity. This discovery can open the way for the development of avocado seed-based health products, as well as educating the public to further appreciate and utilize parts of this frequently neglected fruit. In the future, further research needs to be done to explore other potentials of avocado seeds and the mechanism of action of bioactive compounds contained in it.

Future Directions

Further research is needed to explore the potential of avocado seeds as a source of bioactive compounds. This may involve investigating the effects of different extraction methods on the composition of fatty acids and the antibacterial activity of avocado seed extract. Additionally, studies may be conducted to investigate the mechanism of action of bioactive compounds contained in avocado seeds, as well as their potential applications in the development of natural health products.

Limitations

This study has several limitations. Firstly, the sample size was relatively small, and further studies may be needed to confirm the results. Secondly, the study only investigated the antibacterial activity of avocado seed extract against a limited number of pathogenic bacteria, and further studies may be needed to investigate its activity against other types of bacteria. Finally, the study did not investigate the potential toxicity of avocado seed extract, and further studies may be needed to determine its safety for human use.

Recommendations

Based on the results of this study, it is recommended that further research be conducted to explore the potential of avocado seeds as a source of bioactive compounds. This may involve investigating the effects of different extraction methods on the composition of fatty acids and the antibacterial activity of avocado seed extract. Additionally, studies may be conducted to investigate the mechanism of action of bioactive compounds contained in avocado seeds, as well as their potential applications in the development of natural health products.
