Abstract: Objective: To establish a method for determination of Irone in Iris tectorum. Method: The three isomers of Irone were quantitatively analyzed by GC-MS. Irone in Iris tectorum was determinated according to the extra-calibration curve by GC. Results: The three isomers of irone was speculated according to the MS _ splitting _decomposition law. Irone in two passel of Iris tectorum material was determinated. Conclusion: The analysis method for irone using GC-MS and GC was high- efficient, precise. The analysis time was acceptable.

Key words: Irone, GC, GC-MS
