“…In terms of some components, this study was in agreement with the previous study on Helianthus annuus L. by Ceccarini et al (2004), which belongs to the same sunflower family as yacon, but the main compounds of the essential oil of yacon, such as β-phellandrene, β-cubebene and β-bourbonene were not detected at all in the Czech Republic study (Adam et al, 2005). These differences could be related to the distinct habitat in which the plant was collected, the developmental stage and seasonal variation.…”

The essential oil from the leaves of yacon grown in China was isolated by hydrodistillation and distillation-extraction. Chemical constituents of the essential oil were separated and identified by means of gas chromatography/mass spectrometry (GC/MS) for the first time, and the relative content of each constituent was determined by area normalization. Twenty-one chemical constituents were identified, and their amounts accounted for 96.2% of the total composition. The main components of the essential oil were β-phellandrene (26.3%), β-cubebene (17.7%), β-caryophyllene (14.0%) and β-bourbonene (10.2%). Therefore, in the volatile oil from the leaves of yacon, sesquiterpenes are major compounds, accounting for 52.2%.

“…ards dissolved in p-xylene (A) together with an example of the real HS-SDME extract of M. piperita (B). The chromatographic conditions, including the column selection, were used according to our previous experience [27]. Also herein, these conditions were found as adequate for the evaluation of the HS-SDME chromatograms of analysed samples.…”

A method employing the headspace single-drop microextraction (HS-SDME) is presented for the determination of essential oils in dried herbal leaves. By optimising the key experimental parameters, a linear response for the individual target compounds was obtained in the concentration range from LOQ to 4 mg/mL (r(2) = 0.9912-0.9998), with LODs from 3.3 up to 20.5 microg per 100 g of dried leaves, and the repeatability within the RSD of 2.1-8.9%. The HS-SDME-based procedure, enabling a rapid and simple analysis of essential oils in herbs, was applied to selected real samples (nine essential oils in four different samples) in combination with GC-FID identification and quantification of the target volatiles.

A number of SPME fibers of different polarity and coating thickness are commercially available and have been used for extraction of the volatile compounds in medicinal plants [10][11][12][13][14][15][16][17][18]. Among the fibers, PDMS or PDMS-based mixed fibers are most commonly used.…”
