Chloroform fumigation-extraction procedure were used to evaluate microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN), as described by [63]. To compute the microbial biomass, a conversion factor of 0.45 was used for MBC, and a factor of 0.54 was used for MBN [35]. Soil enzym...
This comparative study, which focused for the first time on different extraction techniques, showed MAE as the most promising procedure to obtain multifunctional AG extracts rich in SAC. The combination of the analytical data provided by the HILIC-ELSD and HPLC-Q MS methods developed in this work...
Briefly, an absolute is an extract obtained from at least two extraction steps. A first extraction step is realized with a nonaqueous volatile extraction solvent—especially non benzenic—and allows to obtain a concrete, when the starting plant matter is fresh or defrosted (after being frozen fo...

3.3. Extraction Procedure The extraction process was performed in an ultrasonic bath (Bandelin Electronic GmbH & Co. KG, Berlin, Germany). Accordingly, 2 g portions of samples were extracted 2-times with 40 mL of 80% ethanol for 40 min at a temperature of 60 °C, ultrasound frequency of ...
The extraction system was by steam distillation in an industrial boiler. The composition of the essential oil is detailed in Table 1, according to an analysis performed by gas chromatography-mass spectrometry (GC–MS) analysis. Oregano oil (1 µL diluted 5% in hexane) was subjected to ...
Finally, the extraction with DCM was performed twice instead of once. A mixture of hexane/ EtOAc (7/3) was used as solvent for the column chromatography. Yield: 3.87 g, 29.72 mmol, 83%. 1H-NMR (600 MHz, CDCl3, RT): δ (ppm) = 5.89 (m, 2H, 2); 5.41–5.50 (m, 4H, 1); ...

For the extraction of pigments from wild garlic leaves, 0.2 g ± 0.01 of the fresh plant material was weighed, and a total of 15 mL of acetone (p.a.) was added three times. After each addition of acetone, the samples were homogenized using a laboratory homogenizer (IKA, UltraTurrax T-...
