The objective of the present study includes estimation of total phenolic and total flavonoid
contents and evaluation of antioxidant and antibacterial activities of various extracts
of Inula cuspidata stem. I. cuspidata belongs to family Compositae; it is an erect shrub, distributed
in western Himalaya, usually found growing on steep rocky or precipitous ground.
Total phenolic and flavonoid contents were estimated by Folin–Ciocalteu and aluminum
chloride method. Antioxidant activity was performed by four methods: DPPH (1,1-diphenyl-
2-picryl hydrazyl radical),ferrous chelating activity, reducing power and nitric oxide scavenging
activity.These extracts were screened for antibacterial studies using macro-dilution method.
