“…In addition to the HAp IR spectral bands, the IR bands specific to lavender EO can also be observed in Figure 4 b. Thus, the bands at 692, 917, 1375 cm −1 correspond to C–H vibrations, while the band at 1640 cm −1 was associated with the C=C stretching vibrations [ 23 , 24 ]. The 1235 cm −1 IR band belongs to the C–O stretching vibration of the ester group, and the 1740 cm −1 band was related to the C=O stretching vibration.…”

The research conducted in this study presented for the first time results of physico-chemical properties and in vitro antimicrobial activity of hydroxyapatite plant essential oil against Gram-positive bacteria (methicillin-resistant Staphylococcus aureus (MRSA) and S. aureus 0364) and Gram-negative bacteria (Escherichia coli ATCC 25922). The samples were studied by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy to determine the morphology and structure of the nanocomposites of hydroxyapatite coated with basil (HAp-B) and lavender (HAp-L) essential oils (EOs). The values of the BET specific surface area (SBET), total pore volume (VP) and pore size (DP) were determined. The results for the physico-chemical properties of HAp-L and HAp-B revealed that lavender EOs were well adsorbed on the surface of hydroxyapatite, whereas basil EOs showed a poor adsorption on the surface of hydroxyapatite. We found that the lavender EOs hydroxyapatite (HAp-L) exhibited a very good inhibitory growth activity. The value of the minimum inhibitory concentration (MIC) related to growth bacteria was 0.039 mg/mL for MRSA, 0.02 mg/mL for S. aureus and 0.039 mg/mL E. coli ATCC 25922. The basil EO hydroxyapatite (HAp-B) showed poor inhibition of bacterial cell growth. The MIC value was 0.625 mg/mL for the HAp-B sample in the presence of the MRSA bacteria, 0.313 mg/mL in the presence of S. aureus and 0.078 mg/mL for E. coli ATCC 25922.

“…The C=C-C stretching vibrations are manifested at 1516 and 1589 cm −1 . The C-H vibrational groups coupled in different chemical configurations present specific IR bands in 2800-3400 cm -1 and 700-1500 cm −1 spectral ranges (see Table 3) [31][32][33][34][35]. The antioxidant and antibacterial properties of A. absinthium L. essential oil and extracts and the antimicrobial mechanisms involved, were reported in several papers.…”

There is significant research showing that essential oils extracted from the plants have antibacterial effects. The purpose of this study was to develop a biocomposite based on hydroxyapatite coated with Artemisia absinthium essential oil and to highlight its antibacterial activity. Therefore, present studies are aimed at developing new materials combining hydroxyapatite with Artemisia absinthium essential oil, in order to avoid postoperative infections. The purpose of this work is to highlight the antimicrobial properties of the Artemisia absinthium essential oil-hydroxyapatite composites obtained by a simple method and at low costs. The structural properties and antimicrobial efficiency of the Artemisia absinthium essential oil-hydroxyapatite composite have been studied. The samples based on Artemisia absinthium essential oil analyzed in this study showed that wormwood essential oil presented the highest efficacy against the fungal strain of C. parapsilosis. It has been shown that wormwood essential oil has a strong antimicrobial effect against the microbial strains tested in this study. Furthermore, the antimicrobial properties of the biocomposites based on hydroxyapatite and essential oil are due to the presence of the essential oil in the samples.

“…Meanwhile, it was overlapping with the CH stretching vibrations in the 3,100–3,000 cm −1 range. Two strong absorption peaks, at 2,940 and 2,860 cm −1 , were associated with the symmetric and asymmetrical stretching vibrations of the saturated CH bonds, from the methyl and methylene groups (Borràs et al, ; Lafhal, Vanloot, Bombarda, Kister, & Dupuy, ). And the absorption peak of the walnut, at 1,470 cm −1 , was linked to the anti‐symmetric deformation of the CH bonds, from the methyl groups, or symmetric deformation of the CH bonds, from the methylene groups.…”

Multiple techniques were employed to extract characteristic fingerprint information of walnuts from the different regions of Xinjiang. Analysis was conducted using near‐ and mid‐infrared spectroscopy, fatty acid and element data to establish geographic classification models of walnuts combined with chemometrics. The least squares discriminant analysis (PLSDA) model had a classification accuracy result of 98.8–100% for walnut samples from different geographical origins by NIR spectra. For the same variety of samples, PLSDA model also had high classification accuracy of 91–100% by MIR spectra. However, variance analysis showed that single element or fatty acid could not be differentiated between the three geographical origins of walnuts. In addition, the back propagation neural network classification model was used to analyze the elements found in the walnut specimens provided results with a mean accuracy of 89.7% for validation. This work demonstrated an acceptable feasibility of using multisource fingerprinting for differentiating regional and characteristic agriculture product to prevent frauds. Practical applications Currently, there is no effective, simple and rapid technology to prevent frauds of walnuts in Xinjiang occurring in the market, especially walnuts with adulteration or which has been counterfeited. Hence, in this research, we provided a feasible method to differentiate the walnut from different regions based on multiple fingerprinting and geographic traceability techniques, which could be applied to prevent frauds of walnuts occurring in the market in the future.
