The samples were purified and concentrated by solid phase extraction, followed by HPLC separation and quantification using a C18 column. The LAS homologues were well separated with prominent peaks corresponding to the different alkyl groups with carbon chainlengths from C10 to C14. The elution of ...
HPLC analysis system using the corresponding commercial C18 column as stated in the experimental procedures at 25 °C with the PDA detector at 300 nm.1H NMR spectra were recorded on Bruker 500 MHz or 400 MHz NMR spectrometers. TopSpin 4.0.5 software was used for NMR data collection and...
The concentration of HMF was carried out by HPLC analysis (Shimadzu LC-20AD, Japan) supplied with an Ultimate Plus-C18 column (150 mm × 4.6 mm) at 30°C. Methanol aqueous (18:82, v:v) solution as the eluent at a flow rate of 1 ml/min. Before the analysis, all the sampl...
In the next step of purification, the crude anthocyanins were separated by semi-preparative HPLC on a Protonsil Eurobond (Bischof, Germany) reverse-phase C18 column (5 μm packing, 4 mm i.d. × 250 mm) protected with a guard column of the same material. Solvents used for the separation...
Overall, the observed and much faster dewetting of water from C8 column than that from C18 column is primarily explained by a higher internal pore connectivity due to the thinner thickness of the alkyl-bonded layer (7 Å versus 15 Å) and, to a lesser extent, by a higher extrusion...
