mono‐demethylated pterostilbene sulfate, mono‐hydroxylated pterostilbene, mono‐hydroxylated pterostilbene glucuronide, mono‐hydroxylated pterostilbene sulfate, and mono‐hydroxylated pterostilbene glucuronide sulfate, using liquid chromatography/atmospheric pressure chemical ionization and electrospray ionization tandem mass spectrometry. The structures of these metabolites were confirmed by analyzing the MSn
藜芦醇,白藜芦醇的二甲氧基衍生物,由于其潜在的有益健康作用,近来备受关注。然而,人们对萜烯的代谢命运知之甚少。在本研究中,我们鉴定了9种新颖的小鼠泌尿性蕨类植物代谢物,萜类植物葡糖醛酸,萜品硫酸盐,单去甲基化的蕨类植物葡糖醛酸,单去甲基化的萜品硫酸盐,单羟基化的萜烯,单羟基化的萜烯,单羟基化的使用液相色谱/大气压化学电离和电喷雾电离串联质谱法对单羟基化的萜茂硫酸葡萄糖苷 通过分析MS n确认这些代谢物的结构(n = 1-3)个光谱。据我们所知,这是鉴定小鼠中蝶形苯尿代谢物的首次报道。版权所有©2010 John Wiley&Sons,Ltd.
