Summary of article contents:
Introduction
Nerium oleander, commonly known as Arali and belonging to the family Apocynaceae, is widely distributed throughout India and utilized in traditional medicine. This plant has various medicinal applications, including the treatment of cancer, cardiac conditions, leprosy, and skin diseases, with significant therapeutic potential due to its active phytochemical constituents. This study aims to analyze the phytochemical properties of Nerium oleander and to assess its antibacterial activity against selected bacterial strains using different solvent extracts.
Phytochemical Analysis and Antibacterial Activity
The phytochemical analysis of Nerium oleander revealed the presence of various bioactive compounds such as terpenoids, alkaloids, cardiac glycosides, saponins, tannins, and carbohydrates, while no flavonoids, phenolic compounds, or phlobatannins were detected. The antibacterial evaluation was conducted through the Disc Diffusion Method, with select bacterial strains (Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella typhimurium) showing notable zones of inhibition in response to the extracts. Specifically, the ethanolic extract exhibited the most significant antibacterial effects, with inhibition zones measuring 10 mm, 9 mm, and 7 mm against Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella typhimurium, respectively.
Conclusion
The findings from this study indicate that Nerium oleander possesses essential phytochemicals that contribute to its antibacterial properties. Given its effectiveness in inhibiting the growth of harmful bacterial species, further research is warranted to isolate the active compounds within the plant extracts. This could pave the way for the development of new drug formulations that leverage the medicinal properties of Nerium oleander to combat various bacterial infections, potentially enhancing traditional medicinal practices with scientific backing.
