An essential oil was extracted from Flos Chrysanthemi Indici by steam distillation with a yield of 0.50%. The oil was analyzed by GC-MS. The analytical conditions were optimized. 54 compounds were separated, and 18 of them were identified from the essential oil. The relative percentage of the constituents were determined by GC with normalization method of area. The relative content of identified constituents accounted for 99.8%.
