Application of UPLC-Q Exactive™ HF-X MS-based untargeted metabolomics reveals variations in Moringa oleifera Lam. leaves from different regions
The metabolites of Moringa oleifera Lam. (M. oleifera) leaves are involved in their biological function. However, a thorough examination of metabolites has not been possible due to the complex nature of metabolite distribution in M. oleifera leaves from different regions. The purpose of this study was to investigate regional differences in M. oleifera leaf metabolite profiles. Leaves from the Dehong, Baoshan, and Yuanmou regions of Yunnan Province were studied using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-Q Exactive™ HF-X MS)-based untargeted metabolomics. A total of 2084 electrospray ionization-positive compounds and 1294 electrospray ionization-negative compounds were identified. The three sample groups were found to be in different quadrants of the principal component analysis (PCA) map; hierarchical cluster analysis (HCA) indicated that variations in habitat conditions were the cause of the unstable quality of M. oleifera leaves; and Kyoto Encyclopedia of Genes and Genomes (KEGG) and orthogonal partial least squares-discrimination analysis (OPLS-DA) showed regional differences in metabolite numbers and associated pathways. These were the observed variations in the chemical compositions of M. oleifera leaves. Flavonoid and phenylpropanoid biosyntheses were the main focus in pathways related to the biosynthesis of other secondary metabolites. Phenolic substances played a significant role as either leaders or connectors in metabolic pathways. The results provide a deeper understanding of phytochemical variations in M. oleifera leaves from different geographical regions which has potential application in the quality control of raw materials.
期刊介绍：
Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology).
In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
