Today, most investigations of the plant metabolome tend to be based on either nuclear magnetic resonance (NMR) spectroscopy or mass spectrometry (MS), with or without hyphenation with chromatography. Although less sensitive than MS, NMR provides a powerful complementary technique for the identification and quantification of metabolites in plant extracts. NMR spectroscopy, well appreciated by phytochemists as a particularly information-rich method, showed recent paradigm shift for the improving of metabolome(s) structural and functional characterization and for advancing the understanding of many biological processes. Furthermore, two dimensional NMR (2D NMR) experiments and the use of chemometric data analysis of NMR spectra have proven highly effective at identifying novel and known metabolites that correlate with changes in genotype or phenotype. In this review, we provide an overview of the development of NMR in the field of metabolomics with special focus on 2D NMR spectroscopic techniques and their applications in phytomedicines quality control analysis and drug discovery from natural sources, raising more attention at its potential to reduce the gap between the pace of natural products research and modern drug discovery demand.
如今,大多数植物代谢组学的研究往往基于核磁共振(NMR)光谱或质谱(MS),或与色谱联用,或不与色谱联用。尽管 NMR 的灵敏度不如 MS,但它为鉴定和定量植物提取物中的代谢物提供了一种强大的互补技术。NMR 光谱作为一种特别信息丰富的方法,深受植物化学家的赞赏,它最近为代谢组学的结构和功能表征的改善以及对许多生物学过程的理解的推进带来了范式转变。此外,二维 NMR(2D NMR)实验和 NMR 光谱的化学计量数据分析的应用已被证明在鉴定与基因型或表型变化相关的新型和已知代谢物方面非常有效。在这篇综述中,我们概述了代谢组学领域中 NMR 的发展,特别关注 2D NMR 光谱技术及其在植物药质量控制分析和天然来源药物发现中的应用,更多地关注其在缩小天然产物研究和现代药物发现需求之间的差距方面的潜力。
