An expanded database of high-resolution MS/MS spectra for lichen-derived natural products
Abstract The history of lichen compound identification has long relied on techniques such as spot tests and TLC, which have been surpassed in sensitivity and accuracy by modern metabolomic techniques such as high-resolution MS/MS.In 2019, Olivier-Jimenez et al.released the Lichen DataBase (LDB), a library containing the Q-TOF MS/MS spectra of 251 m
