Screening Of Phytochemical Constituents And Potential Antioxidant, Antibacterial And Anticancerous Activities Of Carpesium Nepalense Seeds Oil

The pharmacological importance and ecofriendly nature of medicinal plants holding a unique edge in the arena of pharmaceutical industries. Therefore, the current research was aimed to evaluate the phytochemical constituents and potential antioxidant, in vitro anticancer and antibacterial activity of Carpesium nepalense seeds essential oil. The analysis performed through Gas chromatography/Mass spectroscopy confirmed the presence of different types of biologically active compounds. At the concentration of 500 mu g/mL, n-hexane fraction of C. nepalense showed highly significant (P<0.001) antioxidant activity in 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6sulfonic acid and superoxide assays with the percentage inhibitions of 86.60 +/- 1.6%, 82.55 +/- 1.0% and 80.50 +/- 1.0% respectively. The extract also produced highly significant anticancerous activity against different cell lines at 500 mu g/mL. The significant antibacterial activity of extract was observed against bacterial strains with the zone of inhibitions of 24.3 +/- 0.8, 28.20 +/- 0.10, 22.33 +/- 0.11 and 33.22 +/- 0.10 mm respectively. The significant damage in bacterial cell membranes was also observed in atomic force microscopic analysis. In the light of obtained findings, it is concluded that C. nepalence proved to be a potential candidate as an alternative medicinal agent.
