Direct flow injection/electrospray ionization/ion trap tandem mass spectrometry was used to investigate the presence of proanthocyanidins (PAs) in the methanolic extract of B. simaruba bark. Additionally, an LC-ESI-MS qualitative study was performed by using a monolithic stationary phase. The fragmentation pattern obtained evidenced the presence in B. simaruba bark of PAs belonging to the series of polymers of epicatechin, along with their glycosilated derivatives.
采用直接流动注射/电喷雾电离/离子阱串联质谱法研究了苦木树皮甲醇提取物中原花青素（PAs）的存在情况。此外，还使用整体固定相进行了液相色谱-电喷雾质谱定性研究。所得的裂解模式证明了苦木树皮中存在属于表儿茶素聚合物系列的原花青素及其糖基化衍生物。
