Rhomobifoline and 5,6-dehydrolupanine were isolated for the frist time from the leaves and stems of A. foetida L. indigenous to Saudil Arabia. In addition, five other alkaloids, previously identified in A, foetidia L., namely N-methylcytisine, sparteine, anagyrine, lupanine and cytisine, were isolated. The isolated alkaloids were characterized by UV, $^1-NMR,{\;}^{13}H-NMR,{\;}^{13}C-NMR{\;}and{\;}Mass{\;}spectral{\;}data.{\;}^{13}C-NMR$ data of rhombifoline and 5,6-dehydroupanine are reported for the first time.
