Although dihydrobenzofuran neolignans (DBNs) display a wide diversity of biological activities, the identification of their in vivo metabolites using liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI‐MS/MS) remains a challenge to be overcome. Recently, ESI‐MS/MS data of protonated DBNs have been reported, but they were shown to be limited due to the scarcity of diagnostic ions.

去质子化的二氢苯并呋喃新木脂素的电喷雾电离串联质谱

尽管二氢苯并呋喃新木脂（DBN）具有广泛的生物活性，但使用液相色谱/电喷雾串联质谱（LC / ESI-MS / MS）鉴定其体内代谢产物仍然是一个有待克服的挑战。最近，已经报道了质子化DBN的ESI-MS / MS数据，但是由于缺乏诊断离子，因此显示出有限的数据。
