dcterms:description
Desorption electrospray ionization (DESI) mass spectrometry appears to be a useful technique applicable in different areas (e.g. analysis of pharmaceuticals, identification of biologically active compounds in tissues, imaging mass spectrometry). Its modification termed desorption nano-electrospray (nano-DESI) was tested for analysis of anthocyanins. Acidifying of samples and acidic spray liquid (methanol:water = 75:25 with 0.2% HCOOH) were essential for obtaining good quality spectra. Profiles of main anthocyanins in wine samples, two vintages (2005 and 2007) of three cultivars (Alibernet, Neronet and Rubinet), were successfully acquired. They were in agreement with results of LC/MS experiments (anthocyanins isolated by solid phase extraction were separated by mu-HPLC with gradient elution and detected by ESI-MS). Nano-DESI-MS data also allowed to determine ratio of two cultivars (Neronet and Rubinet) in their mixture and to detect coloring of wine by tenturier or elderberry extract. Detection of main anthocyanins in slices of wine grape, chokeberries and elderberries or in a wine stain on cotton fabric is also presented.
