Gynura bicolor is a medicinal plant recognized for its antioxidant potential and natural pigments. This study aimed to evaluate antioxidant activities and bioactive compounds’ contents of G. bicolor extracts and solvent fractions prepared using different drying methods and solvent partitioning. Ethanol extracts were obtained from freeze-dried (FD) and hot-air-dried (HD) samples, followed by sequential partitioning with n-hexane (n-Hex), methylene chloride (MC), ethyl acetate (EA), and n-butanol (n-BuOH). Total polyphenol (TP) and flavonoid (TF) contents were measured. Antioxidant activities were assessed via DPPH and ABTS radical scavenging assays. The FD-EtOH extract showed the highest TP (100.8±0.29 mg TAE/mL) and TF (4.72±0.03 mg QE/mL) contents. EA and n-BuOH fractions exhibited significantly higher antioxidant activity than other fractions, suggesting that bioactive compounds were effectively concentrated through selective solvent extraction. These findings indicate that drying and solvent fractionation can significantly affect antioxidant functionality and phytochemical yield. G. bicolor may serve as a promising natural antioxidant and pigment source for functional food and beverage development.

The aim of this study was to produce a fermented rice bran extract with enhanced ferulic acid γ-oryzanol contents and high antioxidant activities. The ferulic acid content in the freeze-dried extract of rice bran treated with plantase PT enzyme, increased by 4.1-fold compared to that of untreated sample, the DPPH radical scavenging activity also increased by 1.5-fold and 1.2-fold, respectively. The γ-oryzanol content of the dried powder prepared by inoculating Apergillus oryzae BOT1869 onto steamed rice bran for solid-state fermentation followed by extraction with 80% ethanol, increased 2.3-fold compared to that in an 80% ethanol extract powder of raw materials. The ABTS scavenging activity also increased 1.5-fold. When the ferulic acid content-enhanced extract and the γ-oryzanol content-enhanced extract of rice bran were mixed and subjected to liquid fermentation with Lactiplantibacillus pentosus BOT406 and then freeze-dried, the ferulic acid content of the extract powder increased about 3.0 times compared to that of original extract powder. In addition, its γ-oryzanol content increased about 1.5 times, the DPPH radical scavenging activity increased 1.4 times, and the ABTS radical scavenging activity increased 1.6 times.

This study investigated nutrition quotient (NQ) scores of 283 Vietnamese marriage migrant women and their children in Korea and analyzed the influence of maternal dietary adaptation factors on children's dietary quality. The survey was conducted from February 3, 2025 to February 28, 2025. Based on the acculturation theory, mothers were classified into five dietary adaptation types: complete-assimilation, mixed assimilation-separation, integrated-separation, marginalization, and passive-adaptation. Among preschoolers, the complete-assimilation type had the highest total scores of balance (89.0) and practice (83.4), the lowest score of moderation (30.8), and the highest overall NQ-P score (77.8). Among preschool children, the passive-adaptation type showed the lowest total scores for all domains except moderation. In school-age children, the mixed assimilation-separation type had the highest total scores, while the passive-adaptation type had the lowest scores across all domains except moderation. Among mothers, the complete-assimilation type had the highest total scores in balance (88.0), moderation (66.1), and practice (89.6) domains with, the highest overall NQ-A score (82.1), while the passive-adaptation type had the lowest total scores in all domains except moderation. These results confirm that maternal dietary adaptation can affect children's dietary quality highlighting the importance of dietary education and support for mothers during this stage.
