“…However, no studies were performed on the effect of water stress on the composition of essential oils, phenolics, flavonoids, and antioxidant capacity of different populations of D. anethifolia in two consecutive years. As gas chromatography results provide valuable data with many information that is difficult to process based on univariate methods, multivariate analyses provide new tools for exploration and interpretation of chromatographic data [21][22][23] .…”

Ducrosia anethifolia Boiss is a medicinal and aromatic plant that is used as a food additive and drug in the areas of natural distribution. In this study, eight populations from different geographical regions of Iran were evaluated for their essential oil composition, total phenolics and flavonoids as well as for free radical scavenging activity during two consecutive years under water deficit. Analysis of variance was performed using a randomized block design at three levels of irrigation and 2 years, using the GLM procedure of SAS software and cluster analysis was used according to Ward's method using squared Euclidean dissimilarity. The highest essential oil and total phenolics/flavonoids content were obtained in the second year. GC–MS analysis was used to analyze the essential oil components. In normal conditions, cis-chrysanthenyl acetate (39.1–66.4%) and α-pinene (1.02–4.7%) were recognized as major compounds. The essential oil components were elevated under water stress. The highest increase in cis-chrysanthenyl acetate (21.32%) in response to water stress was observed in Abarkuh1. Elevation in total phenolic, flavonoid and antioxidant activity was also observed in plants subjected to water deficit. The highest content of phenolic acids was measured in Semirom (136.74 mg TAE/g DW), while the highest flavonoid content was in Kerman (6.05 mg QUE/g DW) in severe water stress condition. Finally, a high diversity in the studied populations can be used to select advantageous populations for other pharmaceutical and food purposes.

“…Principal component analysis (PCA) is a widely used tool in food and natural-product research. The method has been employed to develop techniques for flour [ 24 ] and honey authentication [ 25 ]. The effect of deep-frying potato and tofu on thermo-oxidative changes in cold-pressed rapeseed oil, high-oleic rapeseed oil and palm olein was investigated by Wroniak et al [ 26 ], and a volatile profile for Kumpiak podlaski dry-cured ham during traditional ripening was developed by Karpinski et al [ 27 ].…”

“…In order to investigate the relationships between the identified polyphenolic compounds and antidiabetic and antioxidant properties on one side and the different extraction conditions on the other, within a multivariate data space, principal component analysis (PCA) and Pearson’s correlation analysis were applied [ 24 ]. PCA is one of the most common multivariate data analysis tools for unsupervised dimensionality reduction and pattern recognition.…”

To study the efficiency of two green-based extraction techniques for the isolation of bioactive constituents from black elderberry press cake, changes in phenolic compounds and main anthocyanin contents were analyzed. Polyphenolic content was correlated with antioxidant and antidiabetic potential by radical-scavenging activity and monitoring of α-amylase inhibition. Black elderberry press-cake extracts were obtained by ultrasound-assisted (UAE) and microwave-assisted (MAE) extractions under different extraction conditions. High-performance liquid chromatography (HPLC) analysis revealed that cyanidin-3-sambubioside and cyanidin-3-glucoside were the principal anthocyanins in all the obtained extracts, with their content being highest in MAE obtained at 80 °C over 5 min. The same extract induced two-fold higher antioxidant activity (IC50 6.89 μg/mL) and α-amylase inhibitory potential (IC50 2.18 mg/mL) in comparison to UAE extracts. The main compositional differences between extracts obtained by the same extraction technique were assigned to the extraction temperature. A principal component analysis confirmed that the antidiabetic feature is to be attributed to the rich content of anthocyanins in black elderberry press cake. Our results indicate the great potential of underutilized black elderberry press cake for the development of novel food and herbal formulations due to notable anthocyanin contents highly correlated with antidiabetic activity.

“…ARs were reported to be stable markers with strong genetic background, unaffected by environmental influences (cultivation place, season, farming system). 6 Pastor et al 7,8 succeeded in differentiating between small-grain flour (wheat, barley, triticale, rye, oat) and corn flour using soluble sugars as target markers, measuring them by gas chromatography-mass spectrometry (GC-MS) and applying multivariate statistics to the obtained data. The comparative study of Zörb et al 9 demonstrated that spelt had 27% higher content of cumulative free sugars than wholemeal common wheat, but our results, presented in figures, were within the range of sugar concentrations reported for wheats in other studies.…”

Identification of biomarkers in hydrosoluble extracts from spelt and wheat cultivated in different production systems

et al. 2020

BACKGROUND: In the present paper, a method for differentiation between common and spelt wheat grown in different farming systems (biodynamic, ecological, integrated, conventional), based on biomarkers identified from aqueous flour extracts (nitrogen and 14 soluble carbohydrates) was employed. RESULTS:The identification and determination of soluble carbohydrate content were carried out using gas chromatographymass spectrometry, with the UV spectrum generated by mass spectrometry for comparison with the WILEY database. Soluble carbohydrates were determined in the peak area between 21.92 and 43.63 min −1 retention time. The obtained data set was analyzed by multivariate statistical techniques. It was revealed that common wheat exerted a much more pronounced tendency than spelt wheat to be influenced by the farming system. CONCLUSION: This differentiation was particularly well visualized after subjecting the data set to principal component analysis (PCA) and cluster analysis (CA). In the PCA graph, all spelt samples were positioned closer to the corresponding control sample, in contrast to the wheat samples, which were distributed over a huge area in the factor space. CA showed that the spelt samples grown under different farming systems were highly similar and grouped into one cluster. Common wheat samples cultivated under organic, biodynamic and integrated system were similar and represented the second cluster, whereas that cultivated under the conventional system was clearly separated from other samples.
