Abstract: Extraction of Clitoria ternatea L. flower were prepared respectively by ultrasonic extraction, super-critical CO₂ extraction and molecular distillation. The volatile components in the extraction were analyzed by GC/MS, and the cigarette flavoring test was carried out. The results showed that the super-critical CO₂ extraction oil had the most quantity of volatile components and the highest relative content, most of which were crucial substances that constitute the flavor of cigarettes. Ultrasonic extraction could extract the potential aroma of tobacco from the Clitoria ternatea L. flower. However, the effect is general, the volatile components of the extract are not as rich as other methods, and the application effect on cigarettes is not as good as other methods. The Clitoria ternatea L. flower extract can be used for cigarette flavoring and casing, which can enhance flavor, increase taste, reduce irritation and improve aftertaste, improve the quality of smoking in general.
