UHPLC flow rates were varied from 200 - 500 渭L/min, with and without the addition of reverse composition of mobile phases, at the parent drug retention time. This change was necessary to achieve uniform MS responses for drugs and their metabolites. In this study, HRMS data, obtained using...

All the three bioactive extracts were subjected to HPLC-DAD and UHPLC-ESI()-HRMS & MS/MS dereplication procedures for correlation purposes. Interesting comparative results related to known constituents such as naphodianthrones, phloroglucinol derivatives and flavonoids were elucidated. To our knowledge,...
The UHPLC-ESI-HRMS/MS analysis of phenolic compounds was performed using a Transcend™ TLX-2 multiplexed LC system coupled to a Q-Exactive hybrid quadrupole-orbitrap mass spectrometer (Thermo Scientific, Hudson, New Hampshire, USA) with a heated electrospray ionization (HESI–II) source. The se...
