Leaf extract is hypotensive. Powdered stem showed antifertility activity in male mice (Asolkar et al., 1992). Andrographolide contained in the plant possesses strong anti-inflammatory and also cytotoxic activity (Ghani, 2003). Both aqueous and ethanolic extract of the plant possesses significant blood sugar lowering effect in both glucose-loaded and alloxen induced diabetic rat (Hossain et al., 2007).
The plant contains principally a resinous bitter sunstance, kalmeghin, the diterpens, andrographolide, andrographiside and neoandrographolide. Extract of the plant also contains 14-deoxy-11-oxoandrographolide, 14-deoyandrographolide, 14-didehydro-andrographolide, epigenin ethers and other flavonoids, phenols and stigmasterol. Leaves contain ß-sitosterol glucoside, andrographolide and panicolide, polyphenols caffeic and chlorogenic acids and a mixture of dicaffeoylquinic acid. Roots contain the flavones, andrographin and panicolinn. The flavonoid glycoside, dihydorxy, dimethoxy-flavone glucoside and diterpene glucoside- neoandrographolide have also been isolated from the roots. Pigments andrographin and panicolin have also been isolated from roots. The ash contains considarable quantities of sodium chloride and potassium salts (Ghani, 2003).
