Analysis of essential oil from different parts of Pelargonium odoratissimum and its application in cigarette

Objective: Develop new natural characteristic plant tobacco flavor. Methods: The volatile oil from the seeds, leaves and stems of Pelargonium odoratissimum 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 Cardamom geranium in cigarette flavoring and conventional components of smoke were compared. Results: The volatile oil of Cardamom geranium seeds was mainly terpinen-4-ol（110.54 mg/g），myristicin（81.81 mg/g），β-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 D-limonene （45.56 mg/g）， linalool（13.26 mg/g）， 3,7-dimethyl-1,5,7-octatrien-3-ol （12.11 mg/g）. Conclusion: Three kinds of volatile oils can give cigarettes unique flavor in varying degrees, improve aroma quality and aroma quantity, and reduce irritation.
