Abstract:
Objective: To study the chemical components from the rhizomes of Cyperus rotundus. Methods: The compounds were isolated and purified by chromatographic techniques, and their structures were elucidated by spectral methods. Results: A new isoflavonoid, 5, 7, 4'-trihydroxy-2'-methoxy-3'-prenylisoflavone (1), along with nine phenolic compounds, 6-O-p-hydroxybenzoyl- 6-epi-aucubin (2), 6-O-p-hydroxybenzoyl-6-epi-monomelittoside (3), verproside (4), syringopicroside B (5), syringopicroside C (6), oleuropeinic acid (7), oleuroside (8), 10-hydroxyoleuropein (9), and senburiside I (10), were obtained from the rhizomes of C. rotundus. Conclusion: Compound 1 is a new isoflavone, named cyperotundone A, and compounds 2-10 are isolated from this plant for the first time.
