Research articles related to Cymbopogon martinii:
Anti- bacterial activity: The present study was designed to judge the in vitro antibacterial activity and comparision of Ocimum basilicum and Cymbopogon martinii. The antibacterial activity was studied in three different concentrations (10μl, 15μl, 20μl) were tested against Streptococcus faecalis and Staphylococcus aureus. At highest concentration of 20μl exhibits more Antibacterial activity and Cymbopgon martini shows more antibacterial activity than Ocimum basilicum in all three concentrations by using Well diffusion method.
Anti- oxidant activity: The present study deals with the in vitro study of antioxidant activity of essential oil from Palmarosa (Cymbopogon martini) of family gramineae. The in vitro study of antioxidant activity of Palmarosa essential oil has been done by using DPPH assay, Nitrogen oxide assay, reducing power assay, carotene bleaching assay and FRAP method. IC50 values observed for DPPH and NO assay were 0.125 mg/mL and 12.5 μg/mL, respectively.In beta carotene bleaching method, the oil showed 93.15% bleaching for the first hour and it increased to 51.1% in second hour. There was a constant increase in the reducing activities with the increase in concentrations in both reducing activity and FRAP methods. In all the methods BHT and Gallic acid were kept as standards. The results clearly indicate that Palmarosa essential oil is effective in scavanging free radical and has the potential to be powerful antioxidant.
