[Chemical constituents from root of Psammosilene tunicoides].
OBJECTIVE
To investigate the chemical constituents from the root of Psammosilene tunicoides.


METHODS
Column chromatographic methods were used to isolate the chemical constituents of this plant. ESI-MS, EI-MS and NMR methods were employed for their structural elucidation.


RESULTS
Seven compounds were isolated and identified as goyaprosaponin (1), Soya-cerebroside (2), tectoridin (3), alpha-spinasterol (4), tetracosanoic acid (5), beta-sitosterol (6), daucosterol (7) respectively.


CONCLUSIONS
Compounds 2-7 were obtained from genus Psammosilene for the first time.
