Chemical Compositions, Effect on Gut Microbiota of Mice, and Flavonoid Transformation of Melanoidin from Guangchenpi of Different Aging-Year wang (25077388) Traditional Chinese medicine and treatments Food sciences not elsewhere classified Biologically active molecules melanoidin, Guangchenpi, gut microbiota, flavonoid transformation, chemical composition <p dir="ltr">The micromorphology characteristics of melanoidin was observed by field emission scanning electron microscope. The Fourier transform infrared spectroscopy and ultraviolet spectroscopy were employed to analyze chemical construction and compositions of melanoidin. The ABTS and DPPH method were used to determine the<i> in vitro</i> antioxidant activity of melanoidins. 16S rRNA gene sequencing technology was employed to investigate the diversity of microorganisms in the feces. We employed gas chromatography-mass spectrometry (GC-MS) targeted metabolomics to detect short-chain fatty acids (SCFAs) in the feces. The <i>in vitro </i>fermentation method was used to investigate the transformation of feces on flavonoid components. The animal experiment was approved by the Experimental Animal Ethics Committee of Guangdong Pharmaceutical University (No.gdpulac2025245).</p> 2026-09-27T01:59:50Z Dataset Dataset 10.6084/m9.figshare.34004103.v1 https://figshare.com/articles/dataset/Chemical_Compositions_Effect_on_Gut_Microbiota_of_Mice_and_Flavonoid_Transformation_of_Melanoidin_from_Guangchenpi_of_Different_Aging-Year/34004103 CC BY 4.0
