LC-HRMS Q-TOF method was used to identify and quantify metabolites of Foleyola billotii Maire 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 glycosylated trans-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 in F. billotii compound profile was more quantitative rather than qualitative.

通过 LC-HRMS Q-TOF 对西撒哈拉特有的十字花科植物 Foleyola Billotii 进行次级代谢物分析

LC-HRMS Q-TOF 方法用于鉴定和定量 Foleyola billotii Maire 植物的代谢物。初步鉴定了 15 种化合物:3 种硫代葡萄糖苷、2 种脂肪族化合物(前甲状腺素和葡糖苷酸)和 1 种吲哚酸(葡糖苷);六种绿原酸、四种香豆酰奎尼酸 (CoQA) 异构体和两种阿魏酰奎尼酸 (FQA) 异构体;两种二糖基化黄酮醇,一种来源于槲皮素,一种来源于山奈酚;三种芥子酸衍生物,芥子酰苏糖酸,己糖芥子酸酯和一种推测归因于阿魏酰奎尼酸芥子酸酯的第三衍生物;最后,一种糖基化的反式肉桂酸,它可以对应于阿魏酰苏糖酸 (FTA)。栽培植物中硫代葡萄糖苷的含量高出 55 倍;绿原酸和黄酮醇也分别增加了 5 倍和 3.5 倍。相比之下,栽培植物中的芥子酸减少了 3 倍,这最后的结果可以用阿尔及利亚北部的 UV-B 强度降低来解释。F. billotii 化合物谱的变化更多是定量的而不是定性的。
