of tomato skin extract, which has an antiallergic activity. In this study, naringenin chalcone was orally administered to rats, and the chemical structures and levels of the major metabolites in the plasma and urine of rats were determined. HPLC analysis indicated the presence of three major metabolites in the urine. LC-MS and NMR analyses tentatively identified these as naringenin chalcone-2′-O-β-d-glucuronide
柚皮素查尔酮是番茄皮提取物的主要活性成分,具有抗过敏作用。在这项研究中,对大鼠口服柚皮苷查尔酮,并测定了大鼠血浆和尿液中主要代谢产物的化学结构和水平。HPLC分析表明尿液中存在三种主要代谢产物。LC-MS和NMR分析初步确定为柚皮苷查尔酮-2' - O - β - d-葡糖醛酸苷,柚皮苷-7- O - β - d-葡糖醛酸苷和柚皮素-4' - O - β - d-葡糖醛酸苷。柚皮素查尔酮-2'- O - β - d-葡萄糖醛酸是血浆中唯一检测到的代谢物,在给予柚皮素查尔酮后1小时观察到其血浆峰值水平。柚皮素查尔酮-2' - O - β - d-葡萄糖醛酸苷还抑制化合物48/80刺激的大鼠腹膜肥大细胞中组胺的释放。此活性可能有助于柚皮素查尔酮在体内的抗过敏活性。据作者所知,该研究是第一个报告测定大鼠血浆和尿液中柚皮素查尔酮代谢物的方法。
