Abstract

Deep eutectic solvents (DESs) were investigated as extracting solvent for headspace single-drop microextraction (HS-SDME). The extraction efficiency of 10 DESs mainly composed of tetrabutylammonium bromide (N 4444 Br) and long-chain alcohols was evaluated for the extraction of terpenes from six spices (cinnamon, cumin, fennel, clove, thyme, and nutmeg). The DES composed of N 4444 Br and dodecanol at a molar ratio of 1:2 showed the highest extraction efficiency and was selected to conduct the extractions of terpenes in the rest of the study. HS-SDME was optimized by design of experiments. Only two parameters from the four studied showed a significant influence on the efficiency of the method: the extraction time and the extraction temperature. The optimal extraction conditions were determined by response surface methodology. All extracts were analyzed by gas chromatography coupled to mass spectrometry (GC-MS). More than 40 terpenes were extracted and identified in nutmeg, the richest extract in terpenes in this study. Quantitative analysis based on 29 standards was conducted for each extract. Good linearity was obtained for all standards (R 2 > 0.99) in the interval of 1 to 500 μg/g. Limits of quantification ranged from 0.47 μg/g (borneol) to 86.40 μg/g (α-farnesene) with more than half of the values under 2 μg/g. HS-SDME is simple, rapid, and cheap compared with conventional extraction methods. The use of DESs makes this extraction method "greener" and it was shown that DESs can be suitable solvents for the extraction of bioactive compounds from plants.

  • Triaux et al.'s DES-HS-SDME application to 27 terpenes showed that half of the studied compounds had LOQs lower than 2 μg/g.

    “The application to 27 different terpens showed that half of the studied compounds had LOQs lower than 2 μg/g”

    From Microextraction Techniques with Deep Eutectic Solvents (2020) · cites this paper as [96]

    Section 3.3 (Calibration) reports that more than half of the studied compounds had LOQs below 2 µg/g, but it gives the calibration count as 29 terpenes, not 27. Section 3.1 uses 27 for a separate solvent-screening comparison, not for the LOQ result. (LLM, conf=0.91)

  • DES-HS-SDME is a simple, cheap, green, and efficient technique for the extraction of terpenes.

    “Therefore, DES-HS-SDME is a simple, cheap, green, and efficient technique for the extraction of terpenes [96].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
