Secondary Metabolite Profiling Via LC-HRMS Q-TOF of Foleyola Billotii , an Endemic Brassicaceae Plant of North-Western Sahara

摘要: LC-HRMS Q-TOF method was used to identify and quantify metabolites of Foleyola billotii Maire plant. A series 15 compounds were tentatively identified: three glucosinolates, 2 aliphatic (progoitrin gluconapin) 1 indolic (glucobrassicin); six chlorogenic acids, four coumaroyl quinic acid (CoQA) isomers two feruloyl (FQA) isomers; diglycosylated flavonols, one quercetin-derived kaempferol-derived; sinapic derivatives, sinapoyl threonic acid, hexose sinapate a third derivative supposedly attributed sinapate; finally, glycosylated trans-cinnamic which could correspond feruloylthreonic (FTA). Glucosinolates content 55 times higher in cultivated plants; acids flavonols increased too by 5 3.5 times, respectively. In contrast, sinapates decreased 3 plants, this last result can be explained reduced UV-B intensity the north Algeria. The change F. compound profile more quantitative rather than qualitative.
