Citronella Essential Oil - ¹H and ¹³C NMR Analysis

The data below shows the ability of ¹³C NMR to assign the natural product distribution found in essential oils. Once assignment of the oil hgas been obtained by ¹³C NMR the ¹H NMR can also be assigned. For QA/QC a benchtop 60 MHz system has enough resolution that authenticity of essential oils can be performed either visually of by PCA type analysis.

Ger - Geraniol         GerAc - Geranyl Acetate        iEugMe - Methylisoeugenol       Bor - Borneol

aPin - alpha-pinene        Lim -  Limonene        tOci - trans-beta-Ocimene      Cen - Camphene

Cllo - Citronellol        Clla - Citronellal        GenD - Germacrene D         aCal - Citral A (Geranial)

aTol - alpha-Terpiniol         cOci - cis-beta-Ocimene        Myr - Myrcene
