Ale-hoof, Gundelrebe, Gundermann. Nepeta glechoma Benth., Nepeta hederacea (L.) Trevis.
Ground ivy contains flavonoids including isoquercitrin, luteolin diglucoside and rutin, and other polyphenohc compounds such as glycosides of icariol, cistanoside E and rosmarinic acid. Other compounds present include beta-sitosterol, the triterpenes oleanolic acid, and alpha- and beta-ursolic acids, and a volatile oil containing the monoterpenes p-cymene, linalool, limonene and terpineol, among others. The sesquiterpene glechomafuran and the diterpene marrubiin are also present. Two alkaloids, hederacine A and B, which may have cytotoxic activity, have been found in very small amounts in the plant.
