Furthermore, the warping was assisted by HPLC-PDA-SPE-NMR-MS (SPE = solid-phase extraction) experiments that yielded 鹿H NMR and 13C NMR data (from 鹿H-detected heteronuclear correlations), as well as ESI-MS and HRMS data, which enabled the identification of all major mixture constituents...
采用UHPLC- 高分辨率 MS 快速分析降解产物。高质量的 HRMS 全扫描图谱为测定降解产物的元素组成提 供了重要信息,并从随后的数据依赖 MS/MS 获得分子离子的裂解信息。 II. 高分辨率 MS/MS 鉴定降解产物的结构 具备阶梯式碰撞能量的高分辨高能碰撞解离功能产生了信息量丰富的碎片,能更轻松地完成降解产物的结构鉴定。
HPLC–PDA/MS/MS based metabolite profiling of avocado seeds In total, fifty-one individual metabolites were tentatively identified in the studied avocado seed hydro-ethanolic extracts via HPLC-PDA/MS/MS analysis. The UV maxima of the metabolites along with their MS/MS parent peaks, daughter fragme...

The HRMS data of these identified metabolites are summarized (seeTable 4andSupplementary: pages S52–S66). The BPCs detected in NI mode were recorded (seeFigure 3c). In addition, the main proposed structures of these metabolites identified from the urine samples of rats that had been administrate...
In the three different methods, the PDA or the UV-Vis detector were set to acquire at 250 or 205 nm, respectively, for the keto boswellic acids (AKBA, KBA) and the boswellic acids (A-BA, B-BA, A-ABA, A-BBA). Slit width was set at 1.2 nm. Acquisition bandwidth was set at ±4...
