Ruta graveolens has been included among unapproved herbs by German Commission E.
The herb contains a volatile oil, with 2-undecanone (30.73) 2-nona- none (18.06), 2-nonyl acetate (11.03), psoralen (1.28) and bergapten and xanthotoxin (7.24%); rutin (about 2%). The flavonoids include quercetin; coumarins include bergapten, daphnoretin, isoimperatorin, naphthoherniarin, psoralen, pangelin, rutamarin, rutarin, scop oletin and umbelliferone. Tissue culture of the plant gave furacridone alkaloids. Tissue culture of the root gave gravacridondiol and its glucoside.
The spasmolytic activity of the herb is attributed to the presence of bergapten, xanthotoxin and the essential oil. Anti-inflammatory and antitumour activity is due to rutin. The furocoumarins are responsible for the herb’s phototoxicity.
