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