Objective：To analyze the chemical constituents of volatile oils extracted from Caesalpinia sappan L. , and provide scientific basis for quality evaluation of it. Methods： Volatile oils were extracted from Caesalpinia sappan L. by water steam distillation and the components were identified by GC-MS. Results ：Altogether,38 peaks were detected and 16 compounds were identified, accounting for 42.01% of the total volatile oils. Among them, （Z, Z ）-9, 12- Octadecadienoic acid （ 10. 53% ）, dibutylphthalate （ 5.02% ）, （ E, E） -2,4-decadienal （ 4. 36% ）, phthalic acid isobutyl nonyl ester （ 3.01% ）, spathulenol （ 2.27% ）, 1,2, 3, 4-Tetrahydro-3- isopropyl-5- methyl-l-oxonaphthalene （ 2. 08% ） were main components, accounting for 27.27% of the total volatile oils. Conclusion： The study provides a scientific basis for the development and utilization of volatile oil from Caesalpinia sappan L..
