Roots are stimulant and tonic (Yusuf et al. 2009). Petrolium ether extract of roots showed anti-ovulatory activity in rabbits (Rastogi & Mehrotra, 1993).
Aerial parts contain several flavonols and flanone glycosides, including quercetin, quercitrin, kaempferol, rutin, persicarin and its methyl ester, hyperoside (quercetin-3-galactoside), rhamnacin and its ester, a dialdehyde sesquiterpene, tadeonal (polygodial) and its isomers, iso-tadeonal and confertifolin, iso-rhamnetin and rhamnazin. The leaves contain an acric essential oil and dimethyl anthraquinones. Presence of tendines, a glucoside, polygopiperin, an inactive alkaloid, tannins and a number of organic acids have also been reported in this plant. Roots contain tannins, ellagic acid, methyl ether, gallic acid, anthraquinone and oxymethyl anthraquinone, quercetin glycosides and iso-coumarin polygonolide. A sesquiterpene dialdehyde, polygodial has also been isolated from this plant (Ghani, 2003).
