Fig. 7 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 7. Levels of major glucosinolates in leaves of first year rosette plants of the Gtype (A) and P-type (B) of Barbarea vulgaris in plants subjected to various challenges or no challenge as control. The contrasting general profile of the types is evident from dominance of BAR in the G-type and EBAR in the P-type. Treatment codes are: Control, un-challenged plants harvested after 7 days; Pieris 3d and Pieris 7d, herbivory by Pieris brassicae larvae until harvest at either day 3 or day 7; Plutella, herbivory by Plutella xylostella for 4 days; CuCl2, spraying of leaves with 10 mM CuCl2 (aq.) followed by recovery for 4 days.

Fig. 9 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 9. Extracted ion HPLC-MS chromatograms of desulfoglucosinolates prepared from glucosinolates (GSLs) in seeds (A–F) or leaves (G) of Reseda luteola and seeds of Reseda odorata (H).

A range of putative derivatives were not detected (E, F), but an unidentified hydroxybutylGSL was present (G), as was a known glycoside in R. odorata.
Fig. 5 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 5. MS2 spectra of desulfated glucosinolates (GSLs) confirming the identity of two 2-3homoMet-derived GSLs in C. hirsuta. While the spectrum of desulfo Buen contains only the usual fragments for this type of dGSL (a, [anhydroGlc+Na]+; b, [thioGlc+Na]+), the spectrum of desulfo Peen contains an additional usual fragment (c, [M-anhydroGlc Na]+) and two unusual + fragment ions suggesting a structure-specific cyclization and exchange of O during fragmentation: 201, [gluconolactone Na]+ and 152, [C H NS Na]+. + 6 11 + The unusual fragments can be rationalized as fragment a plus O and fragment c minus O, respectively.
Fig. 3 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 3. HPLC-MS chromatograms of desulfoglucosinolates (dGSLs) prepared from glucosinolates (GSLs) in Planodes virginica (A) and Nasturtium officinale (B–C) seeds, showing qualitative similarities and quantitative contrasts. Major peaks (B) from N. officinale revealed many of the same GSLs as in A, but levels of EBAR (40R) were much lower while levels were much higher for the biosynthetic precursor PE (105). A focus on trace peaks from N. officinale (C) revealed sharp peaks representing a range of minor constituents. Due to the closely eluting peaks, the latter chromatograms (B–C) were made by combining extracted ion chromatograms corresponding to [M+Na]+ of the indicated dGSLs. In C, the m/z 366 signal of d105 was omitted to allow visualization of minor coeluting peaks. An asterisk after a peak number indicates tentative identification. HPLC-MS conditions as in Olsen et al. (2016). TIC, total ion chromatogram, EIC, extracted ion chromatogram.
Fig. 4 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 4. HPLC-MS chromatogram of desulfoglucosinolates (dGSLs) prepared from glucosinolates (GSLs) from leaves (A) and petioles (B) of horseradish (Armoracia rusticana), focusing on trace level GSLs. The chromatograms were made by combining extracted ion chromatograms corresponding to [M+Na]+ of the indicated dGSLs, from analyses that were much overloaded with respect to the dominating dGSL d107 from Pren. In panel A, an insert shows magnification of the chromatogram from 5.2 to 5.8 min. Neither suggested BAR nor EBAR were detectable. In panel B, only extracted ion chromatograms of m/z 382 (BAR/EBAR), 352 (BZ), 366 (PE), 380 (3PP), 394 (4PB), 408 (5PP at high tR and 6mSOh at 5.4 min), 422 (7mSOh) and 436 (8mSOo) are included. Unlabeled trace peaks did not exhibit a combination of tR and m/z suitable for any of the mentioned candidates. HPLC conditions as in Olsen et al. (2016). Panel A depicts analysis of the Copenhagen garden accession; panel B from the naturalized population at Lake Fures¨o. An asterisk after a peak number indicates tentative identification.

(A–C) Analysis of seeds of Arabidopsis thaliana Col-0 used as reference material for characteristic GSLs. Shown are the total ion chromatogram (A) and extracted ion chromatograms for sodium adducts of desulfo 6′Bz 4BzOb (d125) (B) and desulfo 6′Bz 4mSb (d127) (C). (D–F) Analysis of seeds of Barbarea grayi for dominating GSLs. Shown are total ion chromatograms (D), and extracted ion chromatograms for sodium adducts of desulfo 6'iF BAR (d131S) (E) and desulfo 6'iF PE (d129) (F).
Fig. 1 in Glucosinolate profiles and phylogeny in Barbarea compared to other tribe Cardamineae (Brassicaceae) and Reseda (Resedaceae), based on a library of ion trap HPLC-MS/MS data of reference desulfoglucosinolates
Fig. 1. MS2 spectra of pairs of desulfoglucosinolates with and without a side chain double bond. Four short chain desulfoglucosinolates were investigated, including Na+ adducts of all (A–D) and in addition H+ adducts of the methylthio substituted (E–F), as indicated in each spectrum. The desulfo derivative of the putative 9mSn ([89]), poorly characterized in the literature, was also investigated (G).

Electrodialysis with Bipolar Membranes for the Generation of NaOH and HCl Solutions from Brines: An Inter-Laboratory Evaluation of Thin and Ultrathin Non-Woven Cloth-Based Ion-Exchange Membranes
<p>The SEArcularMINE project aims to recover critical raw materials (CRMs) from brines from saltworks, thus facing a CRM shortage within Europe. To promote a fully circular scheme, the project valorises concentrated brines using electrodialysis with bipolar membranes (EDBM) to generate the required amounts of reactants (i.e., acids and bases). Regarding the performances of new non-woven cloth ion-exchange membranes (Suez): (i) an ultra-thin non-woven polyester cloth and (ii) a thin polypropylene cloth acting as the support structures were assessed. Additionally, the anion layer includes a catalyst to promote the water dissociation reaction. The effect of current density (100, 200, and 300 Am−2) on the performance of two combinations of membranes in an inter-laboratory exercise using 2 M NaCl was evaluated. According to statistical analysis ANOVA, there was an agreement on the results obtained in both laboratories. NaOH/HCl solutions up to 0.8 M were generated working at 300 A m−2 using both combinations of membranes. Regarding the performance parameters, stack set-ups incorporating thin polypropylene membranes showed lower specific energy consumption (SEC) and higher specific productivity (SP) than ultra-thin polypropylene ones. Hence, for ultra-thin polypropylene membranes, SEC was reported to be between 2.18 and 1.69 kWh kg−1 NaOH and SP between 974 and 314 kg m−2 y−1.<br> </p>
