LDB Lichen Database MS/MS spectra of 241 small molecules isolated from lichens collected in the chemical library of S. Huneck (Berlin Garden and Botanical Museum) provided by Harrie Sipman and Robert L??cking. The spectra were produced by three different LC-MS machines, ie and Agilent 6530 qToF (Pierre Le Pogam, University of Paris-Sud, University of Paris-Saclay, Joel Boustie, University of Rennes 1), a Waters Xevo G2-XS qToF (David Rondeau, Thomas Delhaye, University of Rennes 1) and a Thermo Q-Exactive Orbitrap (Jean-Luc Wolfender, Pierre-Marie Allard, University of Geneva). The LDB currently contains more than a thousand spectra across different machines, including diverse adduct spectra in addition to the [M+/-H]. The most common scaffolds in lichens are represented : depsidones, dibenzofuranes, pulvinic acids, paraconic acids, chromones, quinones, xanthones, monoaromatic compounds, quinones, xanthones and chromones. These spectra are not single energy but the consensus of spectra produced at different energies. For Agilent, these were 10, 25 and 40 eV in ESI-, (and also 2.5, 5.0 and 7.5 eV for the more fragile depsides), and 5, 20 and 35 eV in ESI+ or APCI+ for terpenes. For Waters, the collision energies were 10, 20, 30 and 40 eV in ESI- and ESI+. The Thermo spectra were acquired using Normalized Collision Energy (NCE) based on the measured m/z value and three energies : 15, 30, 45 eV.

View GNPS Sciex Library The Sciex dataset contains authentic standards from different compound libraries and single reference standards were used. Specifically, the Agilent LC/MS Pesticide Comprehensive mix, Sigma Aldrich Bile Acid/Carnitine/Sterol Metabolite Library of Standards, Sigma Aldrich Fatty Acid Metabolite Library of Standards and Sigma Aldrich Acid Metabolite Library of Standards were used. Standards were dissolved in suitable solvents and mixed in 43 mixtures in such way to avoid overlap of isomeric and isobaric substances. Standard mixtures were analyzed using a Sciex Exion AD liquid chromatography system coupled to a Sciex X500R QTOF-MS. Separation was achieved on a Phenomenex Kinetex F5 column (150 mm ?? 2.1 mm ID, 2.6 ??m particle size) with a gradient from eluent A (100 % H 2 O + 0.1 % formic acid) to eluent B (100 % acetonitrile + 0.1 % formic acid) using the following gradient: 100/0 at 0 min, 100/0 at 2.1 min, 5/95 at 14 min, 5/95 at 16 min, 100/0 at 16.1 min, and 100/0 at 20 min. Column temperature was set to 30 ??? C and flow rate to 200 ??L/min. Data was acquired by data dependent acquisition of MS/MS spectra using a collision energy ramp from 20 to 50 eV. The MS was automatically recalibrated every five injections in MS1 and MS/MS mode.

View Bile Acid Modifications Library This library consists of 21,549 MS/MS spectra of highest intensity from from the clustered spectra of public data on GNPS/MassIVE recovered using MassQL queries designed for non-, mono-, di-, tri-, tetra- and penta-hydroxylated bile acids. Based on delta masses from unmodified bile acids, the library accounts for 5,576 modified bile acids. Molecular formulae for the delta masses are provided as predicted by two in silico tools, BUDDY and SIRIUS, along with putative explanations when available. In addition, this library also contains MS/MS spectra from synthetic standards of 38 amino acids and 28 polyamines conjugated to bile acids. If the end-users are interested in using this spectral library for structure annotation, they are encouraged to carefully inspect the MS/MS spectrum, perhaps in comparison to the MS/MS spectrum of the conjugate portion proposed to be appended onto the bile acids (if available), to match reporter ions between the two spectra. A very careful manual interpretation of the presence/absence and ratio of ions by bile acid MS/MS fragmentation experts, along with retention time inspection, may facilitate distinction between regioisomers or stereoisomers. This spectral resource can provide unprecedented insights into the new biology of bile acids. Note: This library is not selected by default for search in GNPS and must be explicitly selected in the GNPS workflow from CCMS_SpectralLibraries/GNPS_Propogated_Libraries/GNPS-BILE-ACID-MODIFICATIONS
