This has been made possible by the production of stable permanent magnet technologies that allow high-resolution 1H NMR spectra to be obtained in a process environment. In recent years, NMR has moved out of the research laboratory and into the on-line process analyzer market. Another well-known product of NMR technology has been the Magnetic Resonance Imager (MRI), which is utilized extensively in the medical radiology field to obtain image slices of soft tissues in the human body. Over the next 50 years NMR developed into the premier organic spectroscopy available to chemists to determine the detailed chemical structure of the chemicals they were synthesizing. With the newly developed hardware physicists and chemists began to apply the technology to chemistry and physics problems. The radar technology developed during World War II made many of the electronic aspects of the NMR spectrometer possible. This article provides an overview of the potential uses of NMR techniques and methodologies in an attempt to further promote their recognition and utilization in the field of botanical health products analysis and quality control.Nuclear magnetic resonance spectroscopy (NMR) was first developed in 1946 by research groups at Stanford and M.I.T., in the USA. Furthermore, applications of NMR together with other analytical techniques in a variety of domains of botanical health products investigation, such as plant species differentiation, adulteration detection, and bio-activity evaluation, are discussed and illustrated with typical examples. In this review, NMR techniques and methodologies that have been successfully applied to the research and development of botanical health products in all stages, from plants to products, are discussed and summarized. Nuclear magnetic resonance (NMR) spectroscopy has proven to be a powerful and useful tool for the investigation of botanical health products.

Chemical analytical technologies play an imperative role in addressing these issues. Whereas, quality, safety and efficacy concerns have continuously been critical issues due to the intrinsic chemical complexity of botanicals. During the past few decades in particular, the use of botanical health products has gained more popularity. Botanicals have played an important role in maintaining human health and well-being throughout history.
