Itır (Pelargonium graveolens) Uçucu Yağının FTIR, Raman ve GC-MS Teknikleri Kullanılarak Kimyasal Parmak İzinin Tespit Edilmesi

Itır uçucu yağı, keskin gül benzeri kokusu ile gül esansiyel yağının bir çeşit ikamesi olarak bilinir ve en değerli esansiyel yağlardanbiridir. Eşsiz kalite özellikleri, ıtır esansiyel yağını gıda endüstrisi uygulamaları için çekici kılmaktadır. Bu çalışma, güçlü titreşimspektroskopisi teknikleri (Fourier dönüşümlü kızılötesi spektroskopisi ve Raman spektroskopisi) kullanarak ıtır esansiyel yağının kimyasal parmak izini belirlemiştir. FTIR ve Raman karakterizasyonları, ıtır esansiyel yağının fonksiyonel kimyasal gruplarıtemelinde gerçekleştirilmiştir. Itır uçucu yağının uçucu bileşenlerinin tespiti ve miktarının belirlenmesi için GC-MS (gazkromatografisi-kütle spektroskopu) tekniği kullanılmıştır. 37 (otuz yedi) uçucu bileşen GC-MS analizi ile belirlenmiştir. Relatifolarak en bol miktarda bulunan bileşikler sitronellol (%30.68), geraniol (%9.68) ve sitronelil format (%9.90) olarak belirlenmiştir.

Chemical Fingerprinting of the Geranium (Pelargonium graveolens)Essential Oil by Using FTIR, Raman and GC-MS Techniques

Geranium oil is known as a floral substitute for rose essential oil with its pungent rose-like odor and is one of the most valuableessential oils. Favorable quality properties make the geranium essential oil exigible for food industry applications. This studydetermined the chemical fingerprint of geranium essential oil using robust vibrational spectroscopy techniques (Fourier transforminfrared spectroscopy and Raman spectroscopy). The mid-infrared characterization was accomplished on the basis of functionalchemical groups of geranium essential oil. GC-MS (gas chromatography-mass spectroscopy) technique was used for the detection andquantification of the volatile constituents of geranium essential oil. 37 (thirty-seven) volatile compounds were determined by the GC MS analysis. The most abundant compounds were determined as citronellol (30.68 %), geraniol (9.68%) and citronelly formate(9.90%).
