Introduction
Pentacyclic triterpenoids (PCTs) are secondary plant metabolites. They are of exceptional interest as biologically active substances and raw materials for a wide range of medications. Thus, the development of a methodology for rapid screening of PCTs in plant biomass is an important task.
Objective
The goal of this work was to develop an approach for simultaneous screening and semi‐quantitative...
An array of similar halogenated nitrogen-containing compounds with elemental composition CnH2nNO2X, CnH2n–2NO2X and CnH2n-1NOX2 (X = Cl, Br; n = 16, 18, 22) was detected in drinking water with high performance liquid chromatography – high resolution mass spectrometry (HPLC-HRMS) method. Compounds of this type were never mentioned among disinfection by-products. Tandem mass spectrometry allowed referring...
