Abstract :
The glucosinolate profile of black radish (Raphanus sativus L. niger) based dietary supplements has been investigated by HPLC-PDA, LC-ESI-MS/MS and LC-APCI-MS/MS systems. Optimization of the MS/MS parameters and LC conditions was performed using sinigrin reference standard and rapeseed certified reference material (BC190) respectively. An LC-ESI-MS/MS system was used to detect (screen) and identify the naturally occurring intact glucosinolates (GLs). The intact GLs identified were then desulfated and quantified on an HPLC-PDA system as desulfo-glucosinolates (DS-GLs). Prior to quantification, the DS-GLs were identified using an APCI-MS/MS. The HPLC-PDA method performance criteria were evaluated using glucotropaeolin potassium salt. The validated method was applied for the analysis of six dietary supplements. In total, six glucosinolates were identified and quantified in the dietary supplements; glucoraphasatin (0.2–0.48 mg/g), glucosisaustricin (0.37–0.91 mg/g), glucoraphenin (0.84–1.27 mg/g), glucoputrajivin (0.14–0.28 mg/g), glucosisymbrin (0.70–0.99 mg/g) and gluconasturtiin (0.06–0.12 mg/g). Glucoraphenin was the most abundant glucosinolate in all samples.
