Evaluation of Leaf Extract for its Antibacterial Properties, Mechanism of Action, and Corneal Ulcer Healing Effects in Rabbits' Eyes.

BACKGROUND

is the most adapted tree species in different medicinal eco-systems and has resilience against climate changes. This multiple-use tree provides healthy foods, snacks, honey, and fuel. Besides this, it has immense promising applications by offering antimicrobial and antibacterial activities for targeted uses. This validates the court of Hippocrates that let food be the medicine and medicine be the food for which moringa qualifies.

OBJECTIVE

The objective of this study is to assess the antioxidant properties of antibacterial activity of hydro-ethanolic extract, and further investigate healing potential of for corneal ulcers and analysis.

METHODS

To evaluate the antioxidant and in vitro antibacterial potency of the hydro-ethanolic extract of on clinically isolated multidrug-resistant strains of Staphylococcus aureus using agar well diffusion assay. Furthermore, , healing response of extract was analysed on corneal ulcers induced in rabbit eyes infected with methicillin-resistant Staphylococcus aureus.

RESULTS

The extract exhibited exponential antioxidant activity. antibacterial activity was evaluated by agar well diffusion assay showing zone of inhibition ranging from 11.05 ± 0.36 to 20 ± 0.40 mm at concentrations of 20, 40, 80, and 160 mg/ml, whereas, in our finding, no zone of inhibition was observed below 20 mg/ml concentration, which indicated that there is threshold limit below which the antibacterial activity of extract is not observed. Furthermore, continuous application of 3% and 5% extract (eye drop) four times a day for 14 consecutive days showed a significant healing response of the eyes of rabbits with corneal ulcers.

CONCLUSION

These results suggest that extract could be a viable alternative or in combination could be used in existing antibacterial therapies for corneal ulcers. Additionally, there is a possibility of commercial formulation of extract in the form of deliverable pharmaceutical products; therefore, it should be explored further.
