Summary: This study focused on investigating the antioxidant properties of sulfate monoesters of ferulic, caffeic, dihydroferulic, and dihydrocaffeic acids. These compounds were synthesized in the laboratory as they are not commercially available. LC-MS/MS analysis allowed for the complete characterization of these derivatives, making them reliable standards for further research. The results showed that the hydrogenation of caffeic and ferulic acids improved their reducing properties, but all of the synthesized sulfate monoesters exhibited weak antioxidant properties compared to their precursor compounds.

Summary: Research on mistletoe extracts shows that the chemical composition and antioxidant activity are influenced by factors such as the time and place of harvest, host tree species, and climatic conditions. Chemical analysis and statistical tools were used to evaluate the phenolic composition and antioxidant activity of mistletoe extracts, with findings indicating a rich phenol profile and high antioxidant activity. Chemometric analysis revealed that mistletoe collected from conifers had the most advantageous chemical composition and antioxidant activity, with higher levels of phenolic compounds found in extracts obtained in cold weather with snow and less sunshine.

Summary: This study analyzed the impact of dietary supplementation with blueberry powder on the composition of fecal bile acids (BA). The results showed that the consumption of blueberry powder led to significant increases in glycine-conjugated BAs, glycochenodeoxycholic acid, and glycoursodeoxycholic acid, as well as a significant reduction in secondary BA levels.

Summary: Different culinary techniques have varying effects on the total (poly) phenolic content and antioxidant capacity of artichokes, with frying and griddling showing the lowest content and antioxidant capacity. Boiling also leads to losses of phenolic compounds due to leaching. Overall, heat treatment is shown to best preserve (poly)phenolic compounds in artichokes.

Summary: This study focused on analyzing furan fatty acids (F-acids) in seafood, identifying multiple types of free F-acids in shellfish and salmon. Comparisons revealed basket clams and salmon trout to have significantly higher levels of polyunsaturated fatty acids (PUFAs) among the seafoods analyzed.

Summary: In this study, the metabolomics of Rosa roxburghii fruit at three developmental stages were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). A total of 533 metabolites were identified, with 339 significantly altered. The correlation between total phenols, flavonoids, amino acids and in vitro antioxidant activity was determined. Furthermore, the co-enrichment analysis of metabolome and transcriptome focused on amino acid, phenylpropanoid, and flavonoid biosynthesis pathways. The networks of amino acid, phenolic acid, and flavonol biosynthesis were constructed, and the gene expression was detected in different R. roxburghii genotypes. Key metabolites were identified in the in vitro antioxidant activities at different developmental stages and in different genotypes of R. roxburghii. This study provides novel insights into the synthesis of flavonoids, polyphenols, and amino acids in R. roxburghii.

Summary: This study comprehensively analyzed the antioxidant substances in sour jujube and found that the leaves had significantly higher total phenolic content (TPC) and total flavonoids contents (TFC) than other organs, and exhibited the highest antioxidant activity. The TPC in leaves sampled in May and August was significantly higher than other months. The ethyl acetate fraction obtained from sour jujube leaves displayed the highest TPC and TFC, as well as the best antioxidant activity. LC-MS and HPLC analysis identified several phenolic compounds with high antioxidant activity in sour jujube leaves.
