Objective: The present study deals with the in vitro study of antioxidant activity of essential\udoil from Palmarosa (Cymbopogon martini) of family gramineae. Methods: The in vitro study\udof antioxidant activity of Palmarosa essential oil has been done by using DPPH assay,Nitrogen\udOxide assay , reducing power assay, 毬 -carotene bleaching assay and FRAP method. Results:\udIC\ud50 values observed for DPPH and NO assay are 0.125 mg/ml and 12.5 毺 g/ml respectively.In beta\udcarotene bleaching method the oil showed 93.15% bleaching for the first hour and it increased to\ud51.1% in second hour. There was a constant increase in the reducing activities with the increase\udin concentrations in both reducing activity and FRAP mehods. In all the methods BHT and Gallic\udacid were kept as standards. Conclusions: The results clearly indicate that Palmarosa essential\udoil is effective in scavanging free radical and has the potential to be powerful antioxidant An\udessential oil is a liquid that is generally distilled (more frequently by steam or water) from the\udleaves, stems, flowers, bark or roots or other elements of the plant [1]. These are also known as\udvolatile or ethereal oils. Medicinal applications of essential oils range from skin treatment to\udremedies for cancer
