Antimicrobial, Pesticidal and Food Preservative Applications of Lemongrass Oil Nanoemulsion: A Mini-Review.

BACKGROUND

Essential oils that are extracted from plants have shown beneficial effects on humans and animals, evidenced by traditional medicine. They possess many essential phytocomponents that act as antimicrobial agents, and most of them are safe for external usage.

INTRODUCTION

Lemongrass essential oil is extracted from the grass, such as Cymbopogon flexuosus, and is used for antimicrobial activity for a long time. The efficacy of this oil is limited due to the poor solubility and microbial penetration, easy vaporization, and lower stability. Nanoformulations and nanoencapsulations are nanotechnology fields that aim to improve the bioavailability of many natural compounds and enhance their stability. Lemongrass oil has also been nanoformulated as nanoemulsion, and various antimicrobial activities against various pathogens have been demonstrated, which are superior to free lemongrass oil.

METHODOLOGY

We have used the search engines PubMed and Google Scholar for the mentioned keywords and selected the recent references related to this topic.

CONCLUSION

In this review, we have discussed various antimicrobial properties of lemongrass essential oil nanoemulsion and its application, such as antibacterial, antifungal, pesticidal, food preservative, and antibiofilm activity.
