Application of two-dimensional near-infrared correlation spectroscopy to the discrimination of Chinese herbal medicine of different geographic regions

Recent analytical approaches in quality control of traditional Chinese medicines—A review

“…As a result, in recent years, there has been an increasing trend on the use of NIR for the qualitative and quantitative analysis of TCMs [95]. However, the limitation of NIR is that the classification and quantitation models have to be established before analysis of test samples and that the time required for model development is very long [96].…”

“…Lu et al used such 2D-NIR to discriminate the fruits of Lycium spp. of four different geographic regions successfully [95].…”

Two-dimensional correlation spectroscopy — Biannual survey 2007–2009

“…Issues associated with unevenly sampled data, especially with a relatively large gap, was also discussed by Ashton et al [62]. Lu et al [65] applied vector normalization of raw NIR spectra as a data pretreatment.…”

“…Lu et al [65] used 2D NIR analysis for differentiation of traditional Chinese medicine Fructus lycii from four different geographic regions based on thermal perturbation. Temperature-based 2D IR was used by Jin et al [194] to compare different parts, e.g., radix, stem, and leaf, and extracts of medicinal herb Acanthopanax senticosus Harms.…”

Application of near-infrared spectroscopy for the rapid analysis ofLonicerae Japonicae Flossolution extracted by water

“…15,16 This method is more useful than other analytical techniques because of its rapid speed, accurate prediction, eco-friendliness and low cost. [17][18][19][20][21] This work aims to establish an NIR method for the rapid determination of the concentrations of three active ingredients, chlorogenic acid, secologanic acid and galuteolin, of Lonicerae Japonicae Flos solution extracted by water using high-performance liquid chromatography-diode array detection (HPLC-DAD) as the reference method.…”
