Chemistry
A series of furanoacridones and of two acridone alkaloids (arborinine and evoxanthine) can be isolated from Ruta graveolens. It also contains coumarins and limonoids.
Cell cultures produces the coumarins umbelliferone, scopoletin, psoralen, xanthotoxin, isopimpinellin, rutamarin and rutacultin (6,7-dimethoxy- 3-(1,1-dimethylallyl)coumarin), and the alkaloids skimmianine, kokusaginine, 6-methoxydictamnine and edulinine (1-methyl-4-methoxy-3--2-quinolone).
The ethyl acetate extract of Ruta graveolens leaves yields two furanocoumarins, one quinoline alkaloid and four quinolone alkaloids.
The chloroform extracts of the root, stem and leaf shows the isolation of the furanocoumarin chalepensin.
The essential oil of R. graveolens contains two main constituents undecan-2-one (46.8%) and nonan-2-one (18.8%).
