COMPARATIVE ANALYSIS OF ANTIOXIDANT AND FREE RADICALS SCAVENGING ACTIVITY OF LEMONGRASS OIL AND LAVENDER OIL

Abstract

ABSTRACT
Objective: To compare the free-radical scavenging activity of lemongrass oil and lavender oil.
Methods: Lemongrass oil and lavender oil were used to assess their antioxidant effect by in vitro methods such as phytochemical tests, nitric oxide
radical scavenging activity, and estimation of total phenolic content (TPC).
Results: The oils were studied for different phytoconstituents and show the presence of carbohydrates, tannins, quinones, cardiac glycosides,
terpenoids, phenols, and steroids in both the oils. These constituents can be used in the treatment of diarrhea, hemorrhage, cardiac failure, bacterial
and fungal infections, dermatoses, burns and swollen joints, etc. The TPC of the oils were measured, and results show their use in anticancer and
antioxidant effect. The nitric oxide assay of two oils shows their scavenging activity and their use in controlling blood pressure, platelet functions, etc.
Conclusion: Both the oils show great antioxidant effect. They can be used as a medicinal supplement due to its natural availability and its use in cancer
treatment.
