n-Butylidenephthalide (NBDP) is one of the bioactive constituents originally isolated from Ligusticum chuanxiong Hort. The aim of this study was to study the metabolic profiles of NBDP in rat and human liver microsomes. NBDP was individually incubated with liver microsomes of rat and human at 37°C for 1 h and the samples incubated were analyzed by ultra-high-performance liquid chromatography combined with high-resolution mass spectrometry. The identities of the metabolites were identified by accurate masses, product ions and retention times. Under the current conditions, a total of 14 metabolites were detected and identified. M12, M13 and M14 were biosynthesized and unambiguously characterized by nuclear magnetic resonance spectroscopy. All the metabolites can be detected in rat liver microsomes, whereas in human liver microsomes, M1, M3, M4, M5, M6 and M7 were not detected. Our results demonstrated that the metabolic pathways of NBDP included hydroxylation, hydration, hydrolysis and glutathione conjugation. This study provides an overview of the metabolic profiles of NBDP in vitro, which is helpful to understand the action of this compound.
正丁烯基苯酞（NBDP）是最初从川芎中分离得到的生物活性成分之一。本研究旨在研究 NBDP 在大鼠和人肝微粒体中的代谢谱。将 NBDP 分别与大鼠和人肝微粒体在 37°C 下孵育 1 小时，然后通过超高效液相色谱与高分辨率质谱联用分析孵育样品。通过精确质量、产物离子和保留时间确定代谢物的身份。在当前条件下，共检测到并鉴定了 14 种代谢物。M12、M13 和 M14 通过核磁共振波谱法生物合成并明确表征。所有代谢物均可在大鼠肝微粒体中检测到，而在人肝微粒体中未检测到 M1、M3、M4、M5、M6 和 M7。我们的研究结果表明，NBDP 的代谢途径包括羟化、水合、水解和谷胱甘肽结合。本研究提供了 NBDP 在体外代谢谱的概述，有助于了解该化合物的作用。
