Glucotropaeolin is a glucosinolate that has been found in cruciferous plants such as L. sativum. It has antiprotozoal activity against HM1-IMSS E. histolytica, reducing the number of trophozoites with an IC50 value of 20.4 µg/ml. Dietary administration of glucotropaeolin (1,000 mg/kg), unlike administration of whole glucosinolate extract, does not induce the activity of anticarcinogenic mixed-function oxidases in rat large intestines. Glucotropaeolin is inactive against the fungi F. culmorum and does not have antitumor activity, however, it is metabolized into isothiocyanate products that have these activities.

Screening, identification and quantification of glucosinolates in black radish (Raphanus sativus L. niger) based dietary supplements using liquid chromatography coupled with a photodiode array and liquid chromatography-mass spectrometry
J Chromatogr A 2011 Jul 15;1218(28):4395-405.PMID:21640355DOI:10.1016/j.chroma.2011.05.012
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.
