ABSTRACT
Objective:
To assess in vitro antioxidant activity of the essential oil isolated from fresh rhizomes of garlic (Allium sativum) of the family Alliaceae in an yield of 0.2% (v/w).Methods:
2, 2-diphenyl-1-picrylhydrazyl (DPPH), Nitrogen oxide scavenging, reducing power and毬-carotene bleaching assays were conducted. BHT and gallic acid were kept as standards.Results:
IC50 values observed for DPPH and nitric oxide scavenging assays were 0.5 mg/mL and 50毺g/mL respectively. In reducing power assay absorbance increased linearly with increasing concentration of the oil, in毬-carotene bleaching method also there is 84% bleaching in first one hour and it decreased to 45 % by the completion of second hour.Conclusions:
The results clearly indicate garlic essential oil is effective in scavenging free radical and has the potential to be powerful antioxidant.
