“…The quantitative analysis of the above six compounds showed that the content of 8-HOcA in ACH was significantly higher than that in AMH ( P < 0.05). Here, we notice that the content of DEA in natural honey measured by Kim et al was about 10.9–14.8 mg kg –1 honey, which differs significantly from the content range of this study, probably due to the following reasons: the extraction solvent in this study is ether with weak polarity, which is more suitable for the extraction of lipid-soluble substances, and the addition of a silylation derivatization step further conforms to the gas chromatographic injection conditions; the difference in measurement methods gave a large difference in experimental results. Research results of Kim et al showed that DEA may be involved in the sugar metabolism process in honey bee organisms, while Wurzenberger and Grosch suggested that DEA is generated from linolenic acid (18:3) by oxidation of related enzymes .…”

The authenticity of honey is generally a worldwide concern, and there is a pressing need to establish a suitable entomological method to identify the authenticity of Apis cerana cerana (A. cerana) and Apis mellifera ligustica (A. mellifera) honey. Hydroxy fatty acids as bee-derived components are known to widely exist in honey and other biosamples. Herein, we present an identification strategy for hydroxy fatty acids based on the relative quantification with reference to royal jelly and targeted quantification combined with multivariate statistical analysis to identify the honey entomological origin. Multivariate statistical analysis was used to further determine differential hydroxy fatty acids between A. cerana honey and A. mellifera honey. Results showed that 8-hydroxyoctanoic acid (96.20–253.34 versus 0–32.46 mg kg–1) and 3,10-dihydroxydecanoic acid (1.96–6.56 versus 0–0.35 mg kg–1) could be used as markers for accurate identification of the honey entomological origin, while the three fraud honey samples were recognized using this method. This study provides the novel marker hydroxy fatty acids to identify A. cerana honey and A. mellifera honey from the perspective of bee-derived component differences.

“…To do so, it must present comparability, traceability, and reliability in chemical measurements, proving its adequacy to the intended purpose 10 . The validation of analytical methodologies for the analysis of emerging pollutants in environmental samples has made use of different validation strategies, described in INMETRO 11 and in the literature 12 . In the present work, a laboratory validation study was developed for quick, simple and low-cost quantification of copper and iron metals in aqueous and ethanolic media using an electrode containing a mixed morphology that until now has not been addressed in the literature.…”

Currently, the search for a more economical alternative with adequate selectivity, sensitivity and reproducibility in the determination of metallic ions is important for the development of reliable methodologies for the determination of these contaminants. This work investigates a boron-doped micro/nano diamond electrode, with different morphology and structure compared to those discussed in the literature, for the detection of copper and iron in aqueous and ethanolic environments. Internal validation of the Square Wave Voltammetry was applied. The methodology was submitted to validation by: selectivity, linearity, precision (interday test), accuracy (percentage of recovery) and detection and quantification limits. The results indicated that this type of electrode showed good response to determinations in aqueous and ethanolic environments, with good selectivity, linearity, accuracy (recovery between 70% and 110%) and precision, presenting the best detection and quantification limits for the aqueous. The methodology using a boron-doped diamond micro/nano electrode was suitable for the determination of copper and iron metals in both matrices.
