Abstract:
Methanol extract (ME) of flowerheads Sphaeranthus indicus Linn. and its chromatographic methanol fraction (CMF) were screened for in-vitro antioxidant activity subjecting to DPPH free radical scavenging assay, superoxide scavenging assay, in-vitro lipid peroxidation and determination of reducing power. Both ME and CMF showed potent in-vitro antioxidant activity, whereas, CMF was more effective as free radical scavenger than ME. HPTLC fingerprint were undertaken for identification of active components. Flower-heads of Sphaeranthus indicus demonstrated in-vitro antioxidant activity in present study.

Keywords: Sphaeranthus indicus, DPPH, Superoxide, Lipid Peroxidation.
