OBJECTIVE: In order to exploit the medicinal resources and provide a scientific evidence for the clinical use and quality of Cynomorium songaricum control, the chemical constituents and pharmacological effects of the stem of the plant were studied preliminarily. METHOD: The chemical constituents were studied by spectral analysis and chemical method. The pharmacological effects were studied by an experiment on the defecation and deficiency of kidney function. RESULT AND CONCLUSION: Seven compounds were isolated from the stem of C. songaricum and identified as beta-sitosterol(I), palmitic acid (II), ursloic acid (III), daucosterol (IV), (-)-catechin (VI), naringenin-4'-O-pyranogluoside (VII) and succinicyacid (XII). Compounds VI and XII were isolated from this species for the first time. The pharmacological results show that the different extracts facilitate catharsis and replenish the deficiency of kidney yang.
