[Objective] Chemical composition content in volatile oil of Oldham gypsophila was measured by GC-MS analysis, and simultaneous distillation extraction was also adopted. [Method] Volatile oil was extracted from O. gypsophila by simultaneous distillation extraction. Then, extracts were analyzed by GC-MS. Relative contents of the volatile components were determined by peak area normalization. [Result] A total of 61 volatile components were identified. Among them, 2-ethoxy-propane (12.446 5%), (3-methyl-oxiran-2-yl)-methanol (11.878 5%) and 2-methyl-naphthalene (9.358 6%) were the main components constituting volatile components. [Conclusion] This research provided scientific basis for the further development and utilization of O. gypsophila.
