Abstract: Generally, near infrared spectrum can give information concerning macromolecular high order-vibration energy like carbohydrate, fat and protein. Aromatic citronella oil is composed of compounds with carbon chains of which also has a vibration energy characteristic that is a stretch of near infrared energy range. This paper gives information about characteristics of citronellal, geranial, and citronellol as well as aromatic compounds using of near infrared transflectans spectroscopy that operated on 4,000-10,000 cm-1. Aromatic compounds has been carried out measurements on citronella oil using NIR spectroscopy and gas chromatography mass spectroscopy (GC-MS). Method of measurement i.e. through measuring of spectrum of aromatic compounds on pure aromatic citronella oil, and the aromatic citronella oil also analyzed using of GC-MS. The results showed absorption area aromatics citronella oil ranges between 4000-6200 cm-1. Results of the analysis by GC-MS showed fifteen aromatic compounds contained in the citronella oil with highest percentage citronellal compound (32.9%), geraniol (30.4%) and citronellol (14.3%) compounds respectively, as well as other twelve compounds of as the derivatives of citronellal, geranial and citronellol compounds as much as 22.4%.
