Near-infrared Spectroscopy of Natural Products Including Miniaturized Instruments and Novel Methods of Spectral Analysis
Wednesday, March 10, 2021: 8:30 AM - 8:50 AM
Near-infrared (NIR) spectroscopy is a powerful tool for qualitative and quantitative analysis involving natural products, e.g. plant medicines and also food raw material and processed products. NIR spectroscopy as a rapid and high-throughput analytical method, with on-site capability, high chemical specificity, and no/minimal sample preparation offers significant practical advantages compared to the conventional methods of analysis. Novel portable NIR spectrometers further enhance the potential of this technique. The advantages of NIR spectroscopy are particularly exposed in the field of phytonalaysis. In contrast to synthetic medicines, natural products feature chemical diversity that can vary depending on the medicinal plant cultivation conditions, geographical origin or harvest time. The content bioactive compounds and their derivatives, and thus, the quality parameters of the natural medicine need to be controlled with respect to a number of conditions. NIR spectroscopy is particularly competitive in such difficult scenarios. In recent years, remarkable advances in the field of spectroscopic instrumentation and methods of analysis have appeared. Dynamic development of miniaturized, on-site capable NIR spectrometers and new tools of spectral analysis increase the potential and reliability of NIR spectroscopy in phytonalaytical applications. This talk discusses the major principles of this technique and critically assesses its future application potential in analytical spectroscopy of natural products. The techniques necessary for enabling effective NIR spectral analysis are included as well; the synergy between NIR spectroscopy and reference analysis (separation techniques, e.g. HPLC) and chemical and physical characterization of plant materials including NIR spectral imaging.
