Abstract The roots of Ruta chalepensis, collected from the northern Saudi desert, yielded two new quinoline alkaloids, namely, 2-¿6'-(2H-benzo[d]1' ',3' '-dioxolen-5' '-yl)hexyl¿-hydroquinolin-4-one (1) and 2-¿6'-(2H-benzo[d]1' ',3' '-dioxolen-5' '-yl)hexyl¿-4-methoxy-quinoline (2). Nine previously reported alkaloids, dictamnine, pteleine, skimmianine, rutacridone, isogravacridonechlorine, maculosidine, graveoline, graveolinine, and 4-methoxy-1-methyl-2(1H)-quinolinone, and coumarins, chalepensin, and umbelliferone were also isolated. Structure elucidations were based primarily on 1D and 2D NMR analyses and chemical transformations. Antimicrobial activity of these compounds is discussed.
