OBJECTIVE: To study the microstructure characteristics of nine eyes of Chinese medicine and analyze its volatile oil and trace element composition. Methods: Microscopic observation; Gas chromatogrammass spectrometrycomputer coupled technique for the analysis of volatile oil constituents; Atomic absorption spectrophotometry for the determination of trace elements. RESULTS: The microscopic identification basis for nine eyes was proposed; 36 volatile oil components were identified and the contents of 12 trace and major elemental components were determined. Conclusion: The basis for the microscopic identification of the nine eyes of the Chinese medicine is established, and the reliable data of its volatile oil and trace elements are provided.
