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

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