Eight Components were isolated from The Roots Of Murraya siamensis and their Structures determined by spectroscopic techniques. Seven of the components are carbazole alkaloids, three of which, compounds 4, 6, and 7, are new natural products. The other component is the coumarin xanthoxyletin. A detailed1H-Nmr study of the seven carbazoles in three different solvents (CDCl3, Me2CO-d6, and C6D6) is reported, as well as the13C-nmr spectra of these compounds in Me2CO-d6. © 1990, American Chemical Society.
