Comment lire un spectre IR
  • 3200-3600 cm⁻¹ — élongation O-H (pic large = liaison hydrogène)
  • 2850-3000 cm⁻¹ — élongation C-H (sp³)
  • 1650-1750 cm⁻¹ — élongation C=O (cétones, aldéhydes, esters)
  • 1400-1600 cm⁻¹ — vibrations du cycle aromatique
  • 1000-1300 cm⁻¹ — élongation C-O (éthers, alcools)
  • Aucune absorption = aucun groupe fonctionnel → comparer avec une référence

Dong R, Tian Q, Shi Y, Chen S, Zhang Y, Deng Z, et al. An Integrated Strategy for Rapid Discovery and Identification of Quality Markers in Gardenia Fructus Using an Omics Discrimination-Grey Correlation-Biological Verification Method. Frontiers in Pharmacology. 2021;12:705498. doi:10.3389/fphar.2021.705498
Background: Gardenia Fructus (GF), a traditional Chinese medicine of Gardenia Ellis in Rubiaceae family, has the potential to clear heat and purge fire and has been widely used to treat multiple infection-related diseases. However, the quality markers (Q-Markers) of GF have not been revealed comprehensively. Methods: In this experiment, the transgenic zebrafish lines, Tg (l-fabp:EGFP) and Tg (lyz:EGFP), were used to evaluate two main kinds of traditional efficacies of GF, hepatoprotective and anti-inflammatory effects. All the GF samples from different production areas were tested their anti-liver injury and anti-inflammantory activities. High-performance liquid chromatography-quadrupole time-of-flight mass spectrometry method (HPLC-Q-TOF/MS) was employed for herbal metabonomic analysis of GF samples. Gray correlation analysis (GCA) was utilized to screen out the components closely associated with the activities. Finally, the zebrafish model was applied to verify the bioactivity of the crucial components to determine the Q-Markers of GF. Results: The zebrafish models were established by inducing with hydrogen peroxide or copper sulfate and applied to quickly evaluate the hepatoprotective effect and inflammation of GF samples. 27 potentially active components for liver protection and 21 potentially active components with anti-inflammatory properties were identified by herbal metabolomic analysis based on HPLC-Q-TOF/MS. The GCA result showed that five of the 27 components were highly correlated with liver protection, 15 of the 21 components were highly correlated with anti-inflammatory activity. Among them, geniposide and crocin-1 were confirmed their bioactivities on zebrafish experiment to be responsible for the protective effects of GF against liver injury, and genipin-1-β-D-gentiobioside, quinic acid, gardenoside, d-glucuronic acid, l-malic acid, mannitol, rutin, and chlorogenic acid were confirmed to be responsible for the anti-inflammatory effects. Finally, acco...

Grzelecka M, Siudem P, Tyburc N, Triyasmono L, Holzgrabe U, Paradowska K. Comparison of Quantification Using UV-Vis, NMR, and HPLC Methods of Retinol-Like Bakuchiol Present in Cosmetic Products. International Journal of Molecular Sciences. 2025;26:6638. doi:10.3390/ijms26146638
Retinoids are used in cosmetics as anti-aging ingredients, along with other substances. However, due to limitations in use (such as photodegradation), it seems necessary to look for retinoid alternatives to be applied in cosmetic products. Bakuchiol, a natural alternative of retinoids, isolated from Psolarea corylifolia, is one such compound. It has great cosmetic potential and its mechanism of action is not yet fully explored. From the point of view of the bioactive compound, it is also essential to develop a method for rapid quality control of cosmetic preparations containing bakuchiol. The aim of this study was to apply and compare methods for the quantification of bakuchiol in cosmetic products using UV-Vis, 1H qNMR, and HPLC. The results show the possibility of using the 1H NMR method in the routine quality control of cosmetics with bakuchiol because of its comparable results with HPLC analysis and significantly shorter analysis time.

Pleurotus eryngii produces various functional molecules that mediate physiological functions in humans. Recently, we observed that P. eryngii produces molecules that have antidepressant functions. An ethanol extract of the fruiting body of P. eryngii was obtained, and the extract was purified by XAD-16 resin using an open column system. The ethanol eluate was separated by HPLC, and the fraction with an antidepressant function was identified. Using LC-MS, the molecular structure of the HPLC fraction with antidepressant function was identified as that of tryptamine, a functional molecule that is a tryptophan derivative. The antidepressant effect was identified from the ethanol extract, XAD-16 column eluate, and HPLC fraction by a serotonin receptor binding assay and a cell-based binding assay. Furthermore, a forced swimming test (FST) showed that the mice treated with purified fractions of P. eryngii exhibited decreased immobility time compared with nontreated mice. From these results, we suggest that the extract of P. eryngii has an antidepressant function and that it may be employed as an antidepressant health supplement.

    → OUI : Boucle > 100 µL pour une colonne de 4.6 mm ou connexions desserrées → remplacez les ferrules, raccourcissez les tubes
    → NON : Continuer le diagnostic
  4. 4. Test de température : augmentez la colonne de 25°C à 40°C
    → OUI : Pics plus étroits → cinétique de transfert de masse trop lente (augmentez T)
    → NON : Continue
  5. 5. Vérifiez le débit par rapport à l'optimum de van Deemter pour cette colonne
    → OUI : Optimum pour 4.6mm/5µm = 1.0 mL/min, pour 2.1mm/3µm = 0.4 mL/min
    → NON : Continue
⚠️ Causes courantes :
  • Colonne usée (>2000 injections sans précolonne)
  • Volume mort du système > 100 µL (mauvaise boucle, tubes longs, ferrules desserrées)
  • Température trop basse (cinétique de transfert de masse)
  • Débit hors de l'optimum de van Deemter
  • Solvant d'échantillon plus fort que la phase A
✓ Solutions :
  • ✓ Remplacez la colonne (si >2000 injections)
  • ✓ Vérifiez toutes les connexions — tubes aussi courts que possible
  • ✓ Augmentez la T de la colonne à 40°C (si la substance est stable)
  • ✓ Réduisez le débit à l'optimum de van Deemter
  • ✓ Dissolvez l'échantillon dans la phase A (pas dans un solvant organique pur)
Traînée des pics (tailing, T > 1.5) high

Symptôme : Les pics présentent une "traînée" allongée du côté de l'élution tardive (asymétrie T = b/a > 1.5 selon l'USP)

🔍 Arbre diagnostique :
  1. 1. La substance contient-elle des groupes basiques (amino, pyridine) ?
    → OUI : Oui → interactions silanol ! Ajoutez 0.1% de TFA ou 5-10 mM de TEA à la phase A.
    → NON : Continue
  2. 2. Vérifiez le pH de la phase mobile par rapport au pKa de la substance
    → OUI : pH = pKa ± 1 → ionisation partielle, peak split. Placez le pH à ≥ 2 unités du pKa.
    → NON : Continue
  3. 3. Vérifiez l'âge de la colonne (>1500 injections ?)
    → OUI : Oui → silanols exposés (column bleed). Remplacez par une colonne à endcapping supérieur (XTerra, Symmetry).
    → NON : Continue
  4. 4. L'échantillon contient-il des métaux (Fe, Cu provenant des flacons en verre) ?
    → OUI : Oui → utilisez des flacons incolores de type II ou en PFA. EDTA 0.1mM dans l'échantillon.
    → NON : Continue
⚠️ Causes courantes :
  • Interactions silanol (analyte basique + silanols libres du gel de silice)
  • pH à la limite du pKa de l'analyte (peak split)
  • Colonne ancienne (column bleed, activité silanol élevée)
  • Métaux dans l'échantillon (chélation → traînée)
  • Surcharge de la colonne (>50 µg sur une colonne de 4.6mm)
✓ Solutions :
  • ✓ Ajoutez 0.1% de TFA (UV) ou 0.1% d'acide formique (LC-MS) à la phase A
  • ✓ Choisissez une colonne à endcapping haute pureté : Waters XBridge BEH, Phenomenex Kinetex
  • ✓ Travaillez à un pH ≥ 2 unités du pKa
  • ✓ EDTA 0.1mM dans l'échantillon (chélation Fe/Cu)
  • ✓ Réduisez le volume d'injection à ≤ 20 µL pour une colonne de 4.6mm
Dérive de la ligne de base (baseline drift) medium

Symptôme : La ligne de base monte ou descend systématiquement pendant >5 minutes

🔍 Arbre diagnostique :
  1. 1. Utilisez-vous un gradient (B% augmente) ?
    → OUI : Oui → absorption différente des phases A vs B à dλ. Changement de solvant dans la coupure UV. Vérifiez l'absorbance UV du % d'organique.
    → NON : Continuer (isocratique)
  2. 2. Vérifiez la température de la colonne — est-elle stable à ±0.5°C ?
    → OUI : Oui (stable) → continuer
    → NON : Instable → activez le thermostat de colonne (>25°C contrôlé)
  3. 3. Test : coupez l'échantillonneur automatique, faites fonctionner seuls pompe+colonne+détecteur
    → OUI : La dérive disparaît → contamination de l'échantillonneur automatique (nettoyage de l'aiguille, septum)
    → NON : Continue
  4. 4. Vérifiez l'âge de la lampe (D2 pour UV)
    → OUI : Oui (>1500 heures) → remplacez la lampe
    → NON : Continue
⚠️ Causes courantes :
  • Élution en gradient avec coupure UV différente des phases
  • T de colonne instable
  • Contamination de l'aiguille/septum de l'échantillonneur automatique
  • Lampe UV ancienne (>1500h)
  • Cellule à circulation du détecteur encrassée
  • Colonne non équilibrée (<10 volumes de colonne)
✓ Solutions :
  • ✓ Pré-équilibrez la colonne sur 10-15 volumes de colonne à 100% A
  • ✓ Thermostat de colonne activé, T 30-40°C stable
  • ✓ Nettoyez la cellule à circulation du détecteur avec une solution 50:50 ACN:H2O
  • ✓ Remplacez la lampe D2 si >1500h
  • ✓ Utilisez la soustraction de ligne de base (Chromeleon, fonction native d'Empower)
Absence de pic / pic perdu (no peak) critical

Symptôme : Le pic d'analyte attendu n'apparaît pas sur le chromatogramme

🔍 Arbre diagnostique :
  1. 1. L'injection a-t-elle réellement eu lieu ?
    → OUI : Vérifiez le journal du passeur d'échantillons, la pression des pompes (elle devrait chuter lors de l'injection)
    → NON : Problème de passeur d'échantillons → vérifiez la boucle, l'aiguille, l'échantillon dans le flacon
  2. 2. L'échantillon est-il dans le flacon (volume correct, non évaporé) ?
    → OUI : Continue
    → NON : Pas d'échantillon — repipetez
  3. 3. Stabilité de l'échantillon — préparé il y a >24h ?
    → OUI : Oui → dégradation. Préparez un nouvel échantillon frais.
    → NON : Continue
  4. 4. Vérifiez la longueur d'onde de détection par rapport au λmax de la substance
    → OUI : La détection à λ ne correspond PAS au λmax → pas de signal. Scannez le DAD 200-400nm.
    → NON : Continue
  5. 5. Test : injectez un étalon pur (de concentration connue, frais)
    → OUI : L'étalon donne un pic → problème avec l'échantillon (matrice, dérivatisation)
    → NON : Pas de pic même avec l'étalon → problème du système (colonne, phase, gradient)
⚠️ Causes courantes :
  • Échantillon non prélevé du flacon (bug du passeur d'échantillons)
  • Échantillon dégradé (>24h pH/temp/lumière)
  • Détection à la mauvaise longueur d'onde
  • Phase mobile incorrecte (p. ex. TFA oublié)
  • Colonne inversée / phase stationnaire incorrecte
  • La substance est éluée au front (V0) → non retenue, non visible
✓ Solutions :
  • ✓ Préparez un nouvel échantillon frais selon le protocole exact
  • ✓ Scan UV-Vis DAD 200-400nm + recherche du λmax
  • ✓ Vérifiez la composition de la phase mobile — le TFA a-t-il été ajouté ?
  • ✓ Testez le sens inverse de la colonne (prudemment !)
  • ✓ Pour une rétention <1 min — abaissez le % B, MeOH au lieu d'ACN
  • ✓ Vérifiez la table "expected_rt" dans wp_molgod_hplc_methods
Pression trop élevée (pressure too high) critical

Symptôme : Pression des pompes > 80% du maximum de la colonne ou arrêt du système avec une erreur de haute pression

🔍 Arbre diagnostique :
  1. 1. Vérifiez que la colonne est raccordée correctement (sens de la flèche)
    → OUI : OK
    → NON : Colonne inversée → retournez-la (ne jamais l'utiliser "à l'envers")
  2. 2. Test : retirez la colonne du système, faites tourner la pompe+le détecteur seuls
    → OUI : La pression chute à <50 bar → problème dans la colonne (bouchée)
    → NON : La pression reste élevée → filtre en ligne bouché, fritte encrassée
  3. 3. Vérifiez le filtre de pré-colonne (fritte en ligne)
    → OUI : Encrassé et brun → remplacez-le
    → NON : Continue
  4. 4. Rincez la colonne à contre-courant avec 50:50 ACN:H2O sans la colonne — cela disparaît-il ?
    → OUI : Particules coincées dans le premier mm — un rinçage de 30 min peut la récupérer
    → NON : Remplacez la colonne
⚠️ Causes courantes :
  • Filtre en ligne (fritte) bouché par des particules
  • Relargage du tampon (précipitation à un % B élevé)
  • L'échantillon contient des matières en suspension (filtrer à 0.22 µm avant l'injection)
  • Colonne bouchée (column bed compaction)
  • Gradient avec phase tampon + beaucoup d'organique → précipitation de sel
✓ Solutions :
  • ✓ Filtrez TOUJOURS l'échantillon à 0.22 µm PVDF avant l'injection
  • ✓ Remplacez le filtre en ligne toutes les 100 injections (ou lorsque la pression augmente de >20%)
  • ✓ N'utilisez PAS >20mM de tampon phosphate + >70% d'ACN (le sel précipite)
  • ✓ Rincez la colonne 30 min avec 50:50 ACN:H2O en sens inverse (lorsque le fabricant l'autorise)
  • ✓ Pré-colonne 4×3mm pour protéger la colonne principale
Pics fantômes (ghost peaks) high

Symptôme : Pics inexpliqués sur le chromatogramme, absents de la calibration

🔍 Arbre diagnostique :
  1. 1. Test : injection à blanc (solvant pur de l'échantillon)
    → OUI : Un pic fantôme apparaît → contamination du système ou des éluants
    → NON : Apparaît uniquement avec l'échantillon → matrice
  2. 2. Le pic fantôme croît-il avec le gradient (élue à % B élevé) ?
    → OUI : Oui → colonne surchargée ou composé fortement retenu d'un cycle précédent
    → NON : Indépendant du gradient → effet mémoire (carryover) du passeur d'échantillons
  3. 3. Increase carryover wash (between injections)
    → OUI : Cela aide → l'effet mémoire (carryover) était en cause. Protocole de lavage plus puissant.
    → NON : Continue
  4. 4. Injection d'eau pure — y a-t-il un pic ?
    → OUI : Oui → contamination de la source d'eau (organiques provenant du système DI)
    → NON : Continue
⚠️ Causes courantes :
  • Effet mémoire (carryover) dans l'aiguille/la boucle du passeur d'échantillons
  • Contamination de l'éluant (même de qualité HPLC)
  • Composants fortement retenus de cycles précédents
  • Plastique dans les flacons (phtalates, PEG des capuchons)
  • Eau DI insuffisamment purifiée
✓ Solutions :
  • ✓ Renforcez le protocole de lavage : 100% B → 100% A → 50:50 (3 cycles)
  • ✓ Lavage puissant : DMSO 100% ou MeOH 100% avant la calibration
  • ✓ Filtrez les éluants à 0.22 µm PTFE en cas de doute
  • ✓ Utilisez du verre ambré + des capuchons à revêtement Téflon pour les échantillons
  • ✓ Rampe de gradient périodique jusqu'à 100% B pendant 10 min (nettoyage)

📚 FAQ technique — Dimethyl Sulfoxide (5) MolGod_TECHFAQ_1
❓ Jak przygotować roztwór standardowy DMSO o stężeniu 0.1 M?
Aby przygotować roztwór standardowy DMSO o stężeniu 0.1 M, należy obliczyć masę potrzebnej substancji. Masa molowa DMSO wynosi 78.14 g/mol. Dla 1 litra roztworu (1000 ml) o stężeniu 0.1 M, potrzebna masa DMSO to: 0.1 mol/l * 78.14 g/mol = 7.814 g. Następnie należy odważyć 7.814 g DMSO i rozpuścić w około 900 ml wody destylowanej, a następnie uzupełnić do 1 litra wodą destylowaną.
Utile ?
❓ Jak przechowywać DMSO, aby zachować jego stabilność?
DMSO należy przechowywać w temperaturze pokojowej (15-25°C), z dala od bezpośredniego światła słonecznego i źródeł ciepła. Wilgotność powietrza nie powinna być zbyt wysoka, ponieważ DMSO jest higroskopijny. Zaleca się przechowywanie w szczelnie zamkniętym pojemniku z ciemnego szkła lub tworzywa sztucznego odpornego na rozpuszczalniki organiczne.
Utile ?
❓ Jaka metoda analityczna jest najbardziej odpowiednia do analizy czystego DMSO?
Najbardziej odpowiednią metodą analityczną do analizy czystego DMSO jest chromatografia gazowa (GC) ze względu na jego niską masę molową (78.14 g/mol) i lotność. Alternatywnie, można zastosować wysokosprawną chromatografię cieczową (HPLC), jeśli wymagana jest wyższa rozdzielczość lub analiza w warunkach niskiej temperatury.
Utile ?
❓ Jakie są potencjalne reaktywności i niezgodności chemiczne DMSO?
DMSO jest silnym rozpuszczalnikiem aprotycznym i może reagować z niektórymi metalami, tworząc kompleksy. Może również reagować z silnymi utleniaczami. Nie należy go mieszać z reduktorami organicznymi ani stosować w obecności substancji wrażliwych na utlenianie. DMSO może powodować korozję niektórych metali, takich jak aluminium.
Utile ?
❓ W jakich praktycznych zastosowaniach laboratoryjnych wykorzystuje się DMSO?
DMSO jest powszechnie stosowany jako rozpuszczalnik w syntezie organicznej, do ekstrakcji substancji czynnych z roślin, jako środek konserwujący próbki biologiczne oraz jako nośnik w dostarczaniu leków. Jest również używany w spektroskopii NMR jako rozpuszczalnik deuterowany (DMSO-d6).

  • Heparyna
    Umiarkowane
    CAS partnera: 9005-49-6 · DrugBank DB01109

    Mechanizm: DMSO zwiększa przepuszczalność błon biologicznych i może nasilać układową absorpcję heparyny stosowanej miejscowo. Dodatkowo DMSO wykazuje słabe działanie antyagregacyjne (hamowanie OH• i fibryny).

    Skutek kliniczny: Możliwe nasilenie efektu antykoagulacyjnego i ryzyka krwawienia, zwłaszcza przy aplikacji przezskórnej DMSO + heparyna.

    Postępowanie: Unikać łączenia w aplikacjach skórnych. Monitorować APTT/anty-Xa przy heparynie systemowej i ekspozycji zawodowej na DMSO.
