RESUMEN

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). CONCLUSION: Compounds 1, 4, 5 were isolated from this plant for the first fime.
