Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

Fermentation characteristics of four southern sichuan citrus cultivars
Abstract Background Sichuan, China's leading citrus‐producing region has strong potential for citrus wine development. Citrus is rich in bioactive compounds that enhance flavor and health value, yet current citrus wines often show weak aroma and bitterness.

Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Abstract BACKGROUND Abelmoschus sagittifolius stands out as a valuable medicinal source for developing functional food targeting type 2 diabetes. This study investigated the α‐glucosidase inhibitory potential of an active fraction obtained from A. sagittifolius roots (ASR), enriched in (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid (OA), using both enzyme ...

Evaluation of a retention model in comprehensive two-dimensional gas chromatography
Journal of Separation Science, 2005AbstractModeling the retention in comprehensive two‐dimensional gas chromatography (GC×GC) was achieved using retention indices obtained in conventional GC. Predicted results were compared with experimental data obtained in the two‐dimensional separation of a synthetic hydrocarbon mixture.

The analysis of complex matrices, such as perfumes, by means of gas chromatography-olfactometry (GC-O) can be rather imprecise due to the co-elutions, leading to a possible masking of odour-active trace-level compounds by major interferences or agglomeration of olfactive impressions resulting in unreliable olfactive characterization.

Comprehensive two-dimensional gas chromatography: metrics, potentials, limits
Journal of Chromatography A, 2003Metrics for evaluation of separation performance of comprehensive two-dimensional gas chromatography (GCxGC) and for quantitative comparison of that performance with similar performance of its 1D (one-dimensional) counterparts are described. The performance improvement can be expressed via reduction in the saturation of a chromatogram or-in the case of

Qualitative and quantitative approaches in comprehensive two-dimensional gas chromatography
Journal of Chromatography A, 2012Comprehensive two-dimensional gas chromatography (GC×GC) offers advantages over one-dimensional gas chromatography (GC) including, high peak capacity, signal enhancement, and structured chromatograms. These advantages have been exploited to solve several analytical problems that are difficult to achieve in GC.
