    GC–MS study of compounds isolated from Coffea arabica flowers by different extraction techniques
    (2013-07) Stashenko, Elena E.; Martínez Morales, Jairo René; Cárdenas Vargas, Silvia; Saavedra Barrera, Rogerio; Durán, Diego Camilo
    Headspace (HS), extractive, and distillative methods were employed to isolate volatile and semivolatile compounds from fresh Coffea arabica flowers. Static HS solid-phase microextraction (HS-SPME), microwave-assisted HS-SPME (MW-HS-SPME) with simultaneous hydrodistillation, and extraction with hexane or supercritical CO2-isolated mixtures in which around 150 different chemical substances were identified or tentatively identified by GC–MS analysis. n-Pentadecane (20–37% relative peak area, RPA) was the most abundant compound in the HS fractions from fresh flowers, followed by 8-heptadecene (8–20% RPA) and geraniol (6–14% RPA). Hydrocarbons (mostly C13–C30 paraffins) were the predominant compound class in all the sorptive extractions (HS-SPME, MW-HS-SPME, distillate), followed by terpenoids or oxygenated compounds (which varied with the isolation technique). Caffeine, a distinctive component of coffee fruits and beans, was also found in relatively high amounts in the supercritical CO2 extract of C. arabica flowers.
