Natural products, derived from plants, animals, and microorganisms, have played a pivotal role in human well-being throughout history. Their diverse therapeutic applications, ranging from traditional medicine to modern pharmaceuticals, underscore their immense value. To fully harness the potential of natural products, comprehensive and accurate analysis is crucial, driving the continuous development of innovative analytical techniques and methodologies. This article delves into the recent advancements in natural products analysis, providing researchers with a comprehensive overview of cutting-edge tools and strategies revolutionizing the field.

Chromatographic Techniques

Chromatography remains a cornerstone of natural products analysis, offering unparalleled separation and identification capabilities. Recent years have witnessed substantial advancements in chromatographic techniques, pushing the boundaries of resolution, sensitivity, and automation.

• Ultra-high-performance liquid chromatography (UHPLC) utilizes sub-2 µm particles and high-pressure pumps to achieve ultra-fast separations. This technique has revolutionized the analysis of complex natural product mixtures, enabling the rapid identification and quantification of target compounds.
• Gas chromatography-mass spectrometry (GC-MS) combines the separation power of gas chromatography with the identification capabilities of mass spectrometry. Recent developments in GC-MS technology include the use of advanced mass analyzers, such as time-of-flight (TOF) and quadrupole-time-of-flight (QTOF),providing enhanced sensitivity and accuracy.
• Supercritical fluid chromatography (SFC) utilizes carbon dioxide as the mobile phase, offering unique advantages for the analysis of non-polar and thermally labile natural products. SFC has gained prominence in the analysis of essential oils, lipids, and other lipophilic compounds.

Spectroscopic Techniques

Spectroscopic techniques play a pivotal role in the characterization and identification of natural products. These techniques provide detailed information about the molecular structure and functional groups present in the compound of interest.

• Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for elucidating the structure of natural products. Recent advancements in NMR technology include the development of cryoprobes and high-field magnets, significantly enhancing sensitivity and resolution.
• Mass spectrometry (MS) provides precise mass measurements and fragmentation patterns, facilitating the identification and characterization of natural products. Advances in MS technology include the development of high-resolution mass analyzers and tandem MS techniques, enabling detailed structural analysis.
• Infrared (IR) spectroscopy provides information about the functional groups present in a natural product. Recent developments in IR spectroscopy include the use of Fourier transform infrared (FTIR) and attenuated total reflectance (ATR) techniques, offering enhanced sensitivity and versatility.

Hyphenated Techniques

Hyphenated techniques combine multiple analytical techniques, providing complementary information and enhanced analytical capabilities. These techniques have revolutionized natural products analysis, enabling the comprehensive characterization and identification of complex mixtures.

• Liquid chromatography-mass spectrometry (LC-MS) couples the separation power of LC with the identification capabilities of MS. LC-MS is widely used for the analysis of natural products, providing detailed information about the molecular structure, identity, and quantification of target compounds.
• Gas chromatography-mass spectrometry (GC-MS) combines the separation power of GC with the identification capabilities of MS. GC-MS is particularly valuable for the analysis of volatile natural products, such as essential oils and terpenes.
• Liquid chromatography-nuclear magnetic resonance (LC-NMR) couples the separation power of LC with the structural elucidation capabilities of NMR. LC-NMR is a powerful tool for the identification and characterization of complex natural product mixtures.

Emerging Techniques

In addition to the well-established techniques discussed above, several emerging techniques are gaining prominence in natural products analysis. These techniques offer unique capabilities and hold the potential to further revolutionize the field.

• Metabolomics is a rapidly growing field that utilizes high-throughput analytical techniques to study the comprehensive metabolic profile of an organism or biological system. Metabolomics has the potential to provide unprecedented insights into the biosynthesis, regulation, and biological activity of natural products.
• Imaging mass spectrometry enables the visualization and localization of natural products within complex biological samples. This technique is particularly valuable for the study of natural products in their native environment, providing spatial information about their distribution and localization.
• Biosensors are devices that utilize biological recognition elements to detect and quantify specific analytes. Biosensors have the potential to provide rapid, sensitive, and selective detection of natural products, offering promising applications in quality control and environmental monitoring.
