Taking the extraction efficiency of Chrysanthemum morifolium Ramat flavor concret as the index，the L9（34） orthogonal experimentwas applied to optimize．The volatile compositions in the perfume were prepared with simultaneous distillation and extraction equipment (SDE)．They were isolated and indentified by capillary GC-MS method．The optimal extraction conditmns were obtained as followed：φ (alcohol) = 70％，ultrasonic power 800W and time 30 min．88 peaks compounds were isolated and identified. The relative contents of the total peak area were determined by area normalization method. The main volatile compositions were: (+)-Aromadendrene（9.38%）、n-Hexadecanoic acid（5.11%）、β- Panasinsene（4.63%）、Longifolenaldehyde（4.36%）、α-Cedrene oxide（3.97%）、Eudesma-4(14),11-diene（3.67%）、Isoaromadendrene epoxide（3.35%）、1-Fluoro-2-[(Z)-2-methoxyethenyl]benzene（3.17%）、α-Ylangene（3.15%）、Linolic acid（2.68%）、Alloaromadendren（2.54%）、α-Cyperone（2.35%），etc．The optimum process increased the extraction efficiency of Chrysanthemum morifolium Ramat flavor concret．
