Objective: To identify dihydroflavonol glycoside isomers in Smilax glabra.
Method: The sample was analyzed by HPLC-MS in combination with HPLC-1H-NMR.
Result: Four dihydroflavonol glycoside isomers were identified as astilbin, neoastilbin, isoastilbin, neoisoastilbin.
Conclusion: The method is simple and rapid for the identification of dihydroflavonol glycosides in S. glabra.

The color variation of the leaves in autumn is a significant ornamental feature of Bunge, especially when the leaves gradually become redder. Many studies focused on leaf color changes; however, less research has been conducted on the mechanism by which 's autumn leaves turn red. Red, middle and green leaves of were used as the study materials to evaluate their flavonoid-related metabolites and infer gene and metabolite expression patterns in conjunction with transcriptome expression.

Article Synopsis
- * A study on white, red, and black currants utilized transcriptomics and metabolomics to identify key anthocyanins that determine the fruits' red and purple colors.
- * The research found specific genes and transcription factors that regulate anthocyanin production, enhancing color development in currants during their growth stages.

Anthocyanin-enriched Chinese cabbage has health-enhancing antioxidant properties. Although various regulators of anthocyanin biosynthesis have been identified, the role of individual repressors in this process remains underexplored. This study identifies and characterizes the R2R3-MYB BrMYB32 in Chinese cabbage (Brassica rapa), which acts as a repressor in anthocyanin biosynthesis.

Article Synopsis
- - The study investigates the changes in anthocyanin content and related regulatory genes during the ripening of oil palm fruit, which is important for both its commercial and ornamental value.
- - Analyzing oil palms at different developmental stages revealed a significant decrease in total anthocyanin content as the fruits matured, demonstrating a clear trend over time.
- - Nine genes linked to the anthocyanin biosynthesis pathway were found to be up-regulated during the early developmental stages of the fruit, suggesting their critical role in color development and maturity identification.
The Genome-Wide Identification of the Dihydroflavonol 4-Reductase (DFR) Gene Family and Its Expression Analysis in Different Fruit Coloring Stages of Strawberry.

Dihydroflavonol 4-reductase (DFR) significantly influences the modification of flower color. To explore the role of in the synthesis of strawberry anthocyanins, in this study, we downloaded the CDS sequences of the gene family from the genome database TAIR; the DFR family of forest strawberry was compared; then, a functional domain screen was performed using NCBI; the selected strawberry DFR genes were analyzed; and the expression characteristics of the family members were studied by qRT-PCR. The results showed that there are 57 members of the DFR gene family in strawberry, which are mainly expressed in the cytoplasm and chloroplast; most of them are hydrophilic proteins; and the secondary structure of the protein is mainly composed of α-helices and random coils.
