Essential oils are one of nature's most precious gifts with surprisingly potent and outstanding properties. Coniferous oils, for instance, are nowadays being used extensively to treat or prevent many types of infections, modify immune responses, soothe inflammations, stabilize moods, and to help ease all forms of non-acute pain. Given the broad spectrum of usage of coniferous essential oils, a fast, safe, simple, and efficient sample-preparation method is needed in the estimation procedure of essential oil components in fresh plant material. Generally, the time- and energy-consuming steam distillation (SD) is applied for this purpose. This paper will compare SD, pressurized liquid extraction (PLE), matrix solid-phase dispersion (MSPD), and the sea sand disruption method (SSDM) as isolation techniques to obtain aroma components from Scots pine (Pinus sylvestris), spruce (Picea abies), and Douglas fir (Pseudotsuga menziesii). According to the obtained data, SSDM is the most efficient sample preparation method in determining the essential oil composition of conifers. Moreover, SSDM requires small organic solvent amounts and a short extraction time, which makes it an advantageous alternative procedure for the routine analysis of coniferous oils. The superiority of SSDM over MSPD efficiency is ascertained, as there are no chemical interactions between the plant cell components and the sand. This fact confirms the reliability and efficacy of SSDM for the analysis of volatile oil components.
