A LC-ES-MS/MS method for the identification of dilignols formed by the oxidative cross-coupling of coniferyl alcohol and apocynol has been developed. The identification is based on the generation of ammonium adduct ions M + NH(4) by electrospray ionization and thereafter the following fragmentation patterns for the selected precursor ions. Fragmentation of several arylglycerol-beta-aryl ether (beta-O-4) and phenyl coumarane (beta-5) model compounds were studied as a reference.
已开发出一种用于鉴定松柏醇和夹竹桃酚氧化交叉偶联形成的二芳基木脂醇的液相色谱-电喷雾串联质谱（LC-ES-MS/MS）方法。该鉴定基于通过电喷雾电离产生铵加合离子M + NH₄，以及随后所选前体离子的以下碎裂模式。作为参考，研究了几种芳基甘油-β-芳基醚（β-O-4）和苯基香豆烷（β-5）模型化合物的碎裂情况。
