[Study on the chemical constituents of Rhizoma Cyperi].
OBJECTIVE
To study the chemical constituents of Rhizoma Cyperi.


METHODS
The constituents were separated and purified by silica gel column chromatography, their structures were identified on the basis of physico-chemical properties and spectral data.


RESULTS
Six compounds were isolated and identified as physicion (1), hexadecanoic acid (2), beta-sitosterol (3), stigmasterol (4), catenarin (5), daucosterol (6).


CONCLUSIONS
Compounds 1, 4, 5 were isolated from this plant for the first fime.
