Objective: To study the macroscopic, microscopic identification and chemical components of Cyperus rotundus growing in Wen-River area.
Methods: The features of different parts of Cyperus rotundus were described by material morphology and microscopic identification, the chemical components of aerial part and rhizome of Cyperus rotundus were studied by chemical experiment and GC-MS analysis.
Results: Summarized the transverse section structure of rhizome, stem and leaf of Cyperus rotundus, the chemical components of aerial part and the components and relative content of volatile oil in rhizome were determined.
Conclusion: This study provides reference for the drug identification and the daodi medicinal material exploitation of Cyperus rotundus.
