Two new alkaloids, komavine (1) and acetylkomavine (2) were isolated for th
e first time from the aerial part of Nitraria komarovii. Their H-1 and C-13
NMR spectra were studied. Komavine was synthesized by condensation of tryp
tamine with cyclohexanone. These same alkaloids were also isolated from Nit
raria schoberi.
