“…Fragni et al . 43 investigated forty-one processed tomato samples coming from three different countries by Inductively Coupled Plasma orthogonal acceleration Time-of-Flight Mass Spectrometer (ICP-oa-TOF-MS), exploiting the characteristic of simultaneity of the measurements that is distinctive of this type of instrument. But the objects detected with this method were only metallic elements in plants.…”

Five chemotypes, the isoborneol-type, camphora-type, cineole-type, linalool-type and borneol-type of Cinnamomum camphora (L.) Presl have been identified at the molecular level based on the multivariate analysis of mass spectral fingerprints recorded from a total of 750 raw leaf samples (i.e., 150 leaves equally collected for each chemotype) using desorption atmospheric pressure chemical ionization mass spectrometry (DAPCI-MS). Both volatile and semi-volatile metabolites of the fresh leaves of C. camphora were simultaneously detected by DAPCI-MS without any sample pretreatment, reducing the analysis time from half a day using conventional methods (e.g., GC-MS) down to 30 s. The pattern recognition results obtained using principal component analysis (PCA) was cross-checked by cluster analysis (CA), showing that the difference visualized by the DAPCI-MS spectral fingerprints was validated with 100% accuracy. The study demonstrates that DAPCI-MS meets the challenging requirements for accurate differentiation of all the five chemotypes of C. camphora leaves, motivating more advanced application of DAPCI-MS in plant science and forestry studies.

“…In particular, the capsicum samples from ZYXZ and BJHZ were 100% correctly classified, whereas two capsicum samples from GYHX were incorrectly assigned as samples from ZYXZ (Table 2). Similarly, a good discrimination results of the tomatoes with 99.9% of correctly classified cases was obtained based on LDA in the research of Fragni et al (2015). To assess the predictive ability, the created model was then validated through the leave-one-out cross-validation method.…”

The concentrations of twenty-four elements in twenty-five peppers from three cultivated regions in Guizhou Province (China) were analyzed. The chemometric data processing, including one-way analysis of variance, principal component analysis, linear discriminant analysis (LDA), and orthogonal partial least squares discriminant analysis (OPLS-DA) were executed to differentiate the peppers. Consequently, the contents of 16 elements (Arsenic,

“…Numerous efforts have been devoted to the development of determining the origin of food and plant products (Feligini, Panelli, Sacchi, Ghitti, & Capelli, 2015;Fragni, Trifiro, & Nucci, 2015;Krivachy, Rossmann, & Schmidt, 2015;Popescu et al, 2015). In respect of tea samples, several studies aiming to identify the origin of teas have been performed (Ye, 2012).…”
