Rapid assessment of quality of deer antler slices by using an electronic nose coupled with chemometric analysis

Abstract

Electronic noseDeer antler Lu-Rong Quality A B S T R A C T Deer antler is a precious animal-sourced traditional Chinese medicine. We aimed to rapidly assess the quality of deer antler slices by electronic nose so that we can ensure medical safety. In this study, response intensity of the electronic nose was favorably optimized, and samples were well assessed by using an electronic nose based on LDA model. The results obtained herein suggested that electronic nose could be an effective method to rapidly assess the quality of deer antler slices, and could also be an important tool for categorization of complex aroma mixtures for the control of quality of drugs or food.

Is it possible to rapidly and noninvasively identify different plants from Asteraceae using electronic nose with multiple mathematical algorithms?

“…In CHM identification, E-nose has been used in identification [ 17 ], quality assessment [ 18 ], and geoherbalism evaluation [ 19 ] combined with various multiple mathematical algorithms, such as diffusion maps, or principal component analysis (PCA).…”

Rapid and Accurate Identification of Adulterants via an Electronic Nose and DNA Identification Platform: Identification of Fake Velvet Antlers as an Example

“…Actually, rare studies had reported about discrimination of animalsourced medicinal materials based on specific smells. We firstly established the electronic nose to assess the quality of different deer antler slices [13], and this study is the first attempt to test the electronic nose for discrimination of fake animal-sourced medicinal species. We previously had understood that LDA model was suitable for modeling of velvet antlers [13], so LDA directly was used to test their applicability of discriminating fake velvet antlers in this study.…”

“…A FOX-3000 (Alpha MOS, Toulouse, France), which consisted of a sampling apparatus, array of Table 2. The response values of samples of fake velvet antlers were recorded according to the previous work [13]. The data sets of official or authentic velvet antlers also referred to our previous work [13].…”

Determination of the geographical origin of Tetrastigma hemsleyanum Diels & Gilg using an electronic nose technique with multiple algorithms

“…DNA fingerprinting and microsatellites (including restriction fragment length polymorphisms and amplified fragment length polymorphisms) are effective tools for distinguishing between plant populations. Fingerprinting analysis of traditional Chinese medicine (TCM) represents a comprehensive qualitative approach to species authentication and quality evaluation, and ensures a consistent quality of TCMs ( Wang et al., 2011 ; Xu et al., 2014 ). Gas chromatography (GC) is the preferred method for the analysis of volatiles because of its high reproducibility, while all other methods involve high capital costs, complex operations, and are time consuming ( Tao et al., 2014 ; Yang et al., 2016 ).…”
