Efficient analysis of phytochemical constituents in the peel of Chinese wild citrus Mangshanju (Citrus reticulata Blanco) by ultra high performance liquid chromatography-quadrupole time-of-flight-mass spectrometry

An efficient ultra high‐performance liquid chromatography coupled with quadrupole time‐of‐flight mass spectrometry method was developed for separation and profiling of phytochemical constituents of Chinese wild mandarin Mangshanju ( Citrus reticulata Blanco). All constituents were well separated within 16 min. Based on retention times, accurate mass, MS E fragments, and/or reference standards as well as databases, a total of 81 compounds were...
