Advances of Infrared Spectroscopic Imaging and Mapping Technologies of Plant Material

Infrared spectroscopic imaging studies of medicinal plants

“…The sample itself is analysed either directly or as a thin film mounted onto a calcium or barium fluoride window. 49…”

Recent Developments in Solid-Phase Extraction for Near and Attenuated Total Reflection Infrared Spectroscopic Analysis

“…In attenuated total reflection (ATR) spectroscopy solid and liquid samples can be analyzed without any further sample pre-treatment, mainly in the MIR-region. Fourier-transform infrared (FTIR) spectroscopic microscopy can be used for the investigation of the samples’ composition with a resolution down to approximately 4 µm [56]. Finally, nowadays there is a strong trend towards the miniaturization of spectrometers [57].…”

Infrared Spectroscopic Technologies for the Quality Control of Herbal Medicines

“…The goals of plant IR spectroscopic imaging are to determine the severity of plant diseases, detect defects and contaminations, and determine the distribution of certain chemical components such as cellulose, hemicelluloses, lignin, lipids, proteins, and DNA [64]. An approach to understanding the function and the biochemical composition of plant tissue is one aim of imaging studies.…”

“…IR spectroscopic imaging and mapping technologies have proven to be powerful options for generating new information on plant tissue compositions and alterations. The use of FTIR imaging to evaluate differences in the chemical composition of the Urtica dioica root tissue was described by Pallua et al [64]. Tissue specimens were cut on a microtome at 5-mm thickness and mounted onto CaF 2 -slides.…”
