The human health benefits of anthocyanins (Anc) and other flavonoids are widely recognized. However, the flavonoid-based urinary metabolites arising in vivo after Anc intake are not well described. Human (n = 17) urine was collected while blueberry juice (BJ) was consumed daily for 28 days and once after a 7 day washout. MS/MS scanning of 664 urine samples for 18 parent Anc (PAnc) and 42 predicted Anc metabolites (AncM) yielded 371 products (i.e., MS/MS × retention time (RT)). Flavonoid-based AncM, which were likely underestimated, were almost 20 times more abundant than PAnc. Together, PAnc and AncM accounted for about 1% of the daily Anc dose. Aglycone forms were >94% of the total. Cluster analysis of the 371 Anc identified about 55 major Anc that contributed about 80% to the total Anc. The abundance of flavonoid-based Anc-derived products in the gastrointestinal tract could contribute to the health benefits of Anc-rich berries.
花色苷(Anc)和其他类黄酮对人类健康的益处已得到广泛认可。然而,Anc 摄入后在体内产生的基于类黄酮的尿代谢产物尚未得到很好的描述。17 名志愿者连续 28 天每天饮用蓝莓汁(BJ),并在 7 天洗脱期后再次饮用,在此期间收集他们的尿液。对 664 个尿液样本进行 664 次 MS/MS 扫描,以检测 18 种母体Anc(PAnc)和 42 种预测Anc 代谢物(AncM),共产生 371 种产物(即 MS/MS×保留时间(RT))。AncM 是基于类黄酮的AncM,其含量可能被低估,其丰度几乎是 PAnc 的 20 倍。PAnc 和 AncM 共同占每日 Anc 剂量的约 1%。总共有超过 94%的物质为糖苷形式。对 371 种Anc 的聚类分析确定了大约 55 种主要Anc,它们约占总Anc 的 80%。消化道中基于类黄酮的Anc 衍生产物的丰度可能有助于富含Anc 的浆果发挥其健康益处。
