<b>Objective:</b> Develop new natural characteristic plant tobacco flavor. <b>Methods:</b> The volatile oil from the seeds, leaves and stems of <i>Pelargonium odoratissimum</i> was extracted by simultaneous steam distillation solvent extraction （SDE）. The chemical components of volatile oil were analyzed by GC/MS, and the effects of volatile oil from different parts of <i>Cardamom</i> geranium in cigarette flavoring and conventional components of smoke were compared. <b>Results:</b> The volatile oil of <i>Cardamom geranium</i> seeds was mainly terpinen-4-ol（110.54 mg/g），myristicin（81.81 mg/g），<i>β</i>-phellandrene（58.33 mg/g）. The main components of leaf essential oil were linalool（90.04 mg/g），myristicin（59.09 mg/g）terpinen-4-ol（39.69 mg/g）. The stem essential oil was dominated by <i>D</i>-limonene （45.56 mg/g）， linalool（13.26 mg/g）， 3,7-dimethyl-1,5,7-octatrien-3-ol （12.11 mg/g）. <b>Conclusion:</b> Three kinds of volatile oils can give cigarettes unique flavor in varying degrees, improve aroma quality and aroma quantity, and reduce irritation.
