Cass. belonging to family Asteraceae was subjected to hydro distillation for essential oil extraction and was chemically analyzed by GC/MS for its phytochemical composition. Thirty-five compounds were identified comprising 88.1% of total essential oil composition. Limonene (12.2%) along with sesquisabinene isomer (7.3%) and caryophyllene oxide (5.9%) were the prominent compounds of the essential oil. In-vitro antioxidant activity of essential oil was investigated by DPPH free radical scavenging activity and metal chelating activity having IC50 value of 326.77 ± 5.34 μL and 14.853 ± 0.106 μL respectively whereas reducing power activity having RP50 value of 14.011 ± 0.0446 μL. The essential oil exhibited potent anti-inflammatory activity with IB50 value of 5.629 ± 0.0311 μL compared to standard Diclofenac sodium salt having IB50 value of 23.693 ± 0.306 μg/mL. The essential oil displayed exceedingly marked anti-inflammatory as well as antioxidant activities as compared to standard marketed drugs. Manuscript profile
