Chemical analysis of sweet flag shows that it contains phenyl propanoids, sesquiterpenes and monoterpenes, xanthone glycosides, flavones, steroids, α- and β-asarone and various other constituents. Several, recently published reports have revealed many newer useful bioactivities of leaves and rhizome extracts, essential oils and isolated chemical constituents such as anti-inflammatory, immunosuppressive, anti-adipogenic, antimicrobial, fungicidal, insulin sensitizing/Antidiabetic, neuroprotective, mitogenic, insecticidal, anthelmintic, allelopathic, antiepileptic, insecticidal, larvicidal.
