IR (infrarosso) (8 picchi)
Lo spettro IR (infrarosso) contiene 8 bande identificate. L'analisi seguente spiega che cosa significa ciascuna di esse dal punto di vista strutturale e perché compare in quel determinato intervallo.
C–H stretch (sp3, alkyl)CH3/CH2● high
La banda "C–H stretch (sp3, alkyl)" compare nei casi: 2,898.0 cm⁻¹ (debole (w)). È lo stretching dei legami C–H alifatici sp³. Presente praticamente in ogni composto organico con una catena alchilica.
C–O stretch (alcohol primary, ester)CO● medium
La banda "C–O stretch (alcohol primary, ester)" compare nei casi: 1,092.0 cm⁻¹ (forte (s)). Il gruppo funzionale è identificato in base al suo intervallo caratteristico (Pavia/Silverstein) — il preciso meccanismo fisico dipende dai vicini chimici più prossimi.
C–N stretch (amine), C–O stretch (alcohol/ether)CN/CO● medium
La banda "C–N stretch (amine), C–O stretch (alcohol/ether)" compare nei casi: 1,296.0 cm⁻¹ (debole (w)). Il gruppo funzionale è identificato in base al suo intervallo caratteristico (Pavia/Silverstein) — il preciso meccanismo fisico dipende dai vicini chimici più prossimi.
O–H stretch (broad, COOH dimer)COOH● medium
La banda "O–H stretch (broad, COOH dimer)" compare nei casi: 2,978.0 cm⁻¹ (debole (w)). Un O–H molto largo (~2500–3300) + C=O (~1710) insieme costituiscono la classica firma di un acido carbossilico (dimero).

📖 Sintesi tossicologica
Dimetylosulfotlenek (DMSO, CAS 67-68-5; EC 200-664-3) jest aprotonowym polarnym rozpuszczalnikiem o wyjątkowo niskiej toksyczności ostrej. LD50 doustnie u szczura wynosi 14 500 mg/kg masy ciała wg dossier ECHA REACH [1] i danych RTECS [2]; cross-referencja [1,2]; substancja klasy 5 Hodge'a i Sternera ("praktycznie nieszkodliwa"). NIOSH nie ustala limitów narażenia zawodowego; substancja nie figuruje w listach OSHA PEL ani ACGIH TLV [3]. IARC nie zaklasyfikowała DMSO [4]; brak CMR w Aneksie VI CLP [1]. DMSO jest zatwierdzonym przez FDA nośnikiem farmaceutycznym (Inactive Ingredient Database) w preparatach miejscowych i pozajelitowych; lecznicze zastosowanie DMSO zostało zatwierdzone przez FDA w 1978 r. dla śródpęcherzowego leczenia śródmiąższowego zapalenia pęcherza (DMSO 50%) [5]. Wyjątkowa właściwość penetracji: DMSO przenika skórę i błony biologiczne w ciągu sekund, transportując jednocześnie cząsteczki rozpuszczone — wymaga ostrożności przy jednoczesnej ekspozycji na inne substancje chemiczne. Charakterystyczny marker narażenia: przenoszenie zapachu "czosnku/ostryg" do wydychanego powietrza i moczu przez metabolit dimetylosulfid [6].

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.

Park Y, Jang S, Lee H, Kang S, Seo H, Yeon S, et al. Identification of the Antidepressant Function of the Edible Mushroom Pleurotus eryngii. Journal of Fungi. 2021;7:190. doi:10.3390/jof7030190
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.

Diagnostica dei 12 problemi HPLC più comuni con albero decisionale (5 passaggi per problema). Fonte: Snyder/Kirkland/Dolan 3rd ed. Chapter 17 + LCGC LC Troubleshooting columns 1989-2024.
Picchi allargati (broad peaks) medium
Sintomo: Tutti i picchi nel cromatogramma sono più larghi del previsto (FWHM > 2× della norma)
🔍 Albero diagnostico:
1. Verifica se tutti i picchi sono allargati o solo alcuni → SÌ: Tutti → problema strumentale (colonna o sistema) → NO: Solo alcuni → problema chimico (interazione con la colonna per analiti specifici)
2. Sostituisci con una colonna di prova — il problema scompare? → SÌ: COLONNA usurata — packing danneggiato, void nei primi mm. Sostituiscila. → NO: Problema nel sistema LC
3. Controllare il volume morto (dead volume) — loop di iniezione, connessioni, rivelatore → SÌ: Loop > 100 µL per una colonna da 4.6 mm o connessioni allentate → sostituire le ferrule, accorciare i tubi → NO: Continua diagnostica
4. Test di temperatura: aumentare la colonna da 25°C a 40°C → SÌ: Picchi più stretti → cinetica di trasferimento di massa troppo lenta (aumentare T) → NO: Continue
5. Controllare il flow rate rispetto al valore ottimale di van Deemter per questa colonna → SÌ: Ottimale per 4.6mm/5µm = 1.0 mL/min, per 2.1mm/3µm = 0.4 mL/min → NO: Continue
⚠️ Cause comuni:
Colonna usurata (>2000 iniezioni senza guard)
Volume morto del sistema > 100 µL (loop errato, tubi lunghi, ferrule allentate)
Temperatura troppo bassa (cinetica di trasferimento di massa)
Flow rate al di fuori dell'ottimale di van Deemter
Solvente del campione più forte della fase A
✓ Soluzioni:
✓ Sostituire la colonna (quando >2000 iniezioni)
✓ Controllare tutte le connessioni — tubi il più corti possibile
✓ Aumentare la T della colonna a 40°C (se la sostanza è stabile)
✓ Ridurre il flow all'ottimale di van Deemter
✓ Sciogliere il campione nella fase A (non in organico puro)
Coda dei picchi (tailing, T > 1.5) high
Sintomo: I picchi presentano una "coda" prolungata sul lato di eluizione tardiva (asimmetria T = b/a > 1.5 secondo USP)
🔍 Albero diagnostico:
1. La sostanza contiene gruppi basici (ammino, piridina)? → SÌ: Sì → interazioni silanoliche! Aggiungere 0.1% TFA o 5-10 mM TEA alla fase A. → NO: Continue
2. Controllare il pH della fase mobile rispetto al pKa della sostanza → SÌ: pH = pKa ± 1 → ionizzazione parziale, peak split. Portare il pH a ≥ 2 unità di distanza dal pKa. → NO: Continue
3. Controllare l'età della colonna (>1500 iniezioni?) → SÌ: Sì → silanoli esposti (column bleed). Sostituire con una colonna con endcapping più elevato (XTerra, Symmetry). → NO: Continue
4. Il campione contiene metalli (Fe, Cu dalle fiale di vetro)? → SÌ: Sì → utilizzare fiale incolori di tipo II o PFA. EDTA 0.1mM nel campione. → NO: Continue
⚠️ Cause comuni:
Interazioni silanoliche (analita basico + silanoli liberi del gel di silice)
pH al limite del pKa dell'analita (peak split)
Colonna vecchia (column bleed, elevata attività silanolica)
Metalli nel campione (chelazione → tailing)
Sovraccarico della colonna (>50 µg su una colonna da 4.6mm)
✓ Soluzioni:
✓ Aggiungere 0.1% TFA (UV) o 0.1% acido formico (LC-MS) alla fase A
✓ Scegliere una colonna con endcapping ad alta purezza: Waters XBridge BEH, Phenomenex Kinetex
✓ Lavorare a pH ≥ 2 unità di distanza dal pKa
✓ EDTA 0.1mM nel campione (chelazione Fe/Cu)
✓ Ridurre il volume di iniezione a ≤ 20 µL per una colonna da 4.6mm
Deriva della linea di base (baseline drift) medium
Sintomo: La linea di base aumenta o diminuisce sistematicamente per >5 minuti
🔍 Albero diagnostico:
1. Si sta utilizzando un gradiente (B% in aumento)? → SÌ: Sì → assorbimento diverso delle fasi A e B a dλ. Cambio di solvente nell'UV-cutoff. Controllare l'assorbanza UV del % di organico. → NO: Continua (isocratico)
2. Controllare la temperatura della colonna — è stabile a ±0.5°C? → SÌ: Sì (stabile) → continua → NO: Instabile → attivare il termostato della colonna (>25°C controllato)
3. Test: spegnere l'autosampler, far funzionare solo pompa+colonna+rivelatore → SÌ: La deriva scompare → contaminazione dell'autosampler (pulire l'ago, il septum) → NO: Continue
4. Controllare l'età della lampada (D2 per UV) → SÌ: Sì (>1500 ore) → sostituire la lampada → NO: Continue
⚠️ Cause comuni:
Eluizione a gradiente con UV-cutoff diverso delle fasi
T della colonna instabile
Contaminazione dell'ago/septum dell'autosampler
Lampada UV vecchia (>1500h)
Cella di flusso del rivelatore sporca
Colonna non equilibrata (<10 volumi di colonna)
✓ Soluzioni:
✓ Pre-equilibrare la colonna per 10-15 volumi di colonna al 100% A
✓ Termostato colonna attivo, T 30-40°C stabile
✓ Pulire la flow cell del rivelatore con soluzione ACN:H2O 50:50
✓ Sostituire la lampada D2 se >1500h
✓ Usare la baseline subtraction (funzione nativa Chromeleon, Empower)
Nessun picco / picco perso (no peak) critical
Sintomo: Il picco atteso dell'analita non compare nel cromatogramma
🔍 Albero diagnostico:
1. L'iniezione è stata effettivamente eseguita? → SÌ: Controllare il log dell'autocampionatore, la pressione della pompa (dovrebbe calare durante l'iniezione) → NO: Problema dell'autocampionatore → controllare il loop, l'ago, il campione nella fiala
2. Il campione è nella fiala (volume corretto, non evaporato)? → SÌ: Continue → NO: Nessun campione — ri-pipettare
3. Stabilità del campione — preparato >24h fa? → SÌ: Sì → degradazione. Ri-preparare un campione fresco. → NO: Continue
4. Controllare la lunghezza d'onda di rilevazione rispetto al λmax della sostanza → SÌ: Rilevazione a λ NON corrisponde al λmax → nessun segnale. Scansione DAD 200-400nm. → NO: Continue
5. Test: iniettare uno standard puro (di concentrazione nota, fresco) → SÌ: Lo standard dà un picco → problema con il campione (matrice, derivatizzazione) → NO: Nessun picco anche con lo standard → problema di sistema (colonna, fase, gradiente)
⚠️ Cause comuni:
Campione non prelevato dalla fiala (bug dell'autocampionatore)
Campione degradato (>24h pH/temp/luce)
Rilevazione alla lunghezza d'onda errata
Fase mobile errata (es. TFA dimenticato)
Colonna invertita / fase stazionaria errata
La sostanza eluisce sul fronte (V0) → non trattenuta, non visibile
✓ Soluzioni:
✓ Ri-preparare un campione fresco secondo il protocollo esatto
✓ Scansione UV-Vis DAD 200-400nm + ricerca del λmax
✓ Controllare la composizione della fase mobile — TFA aggiunto?
✓ Testare la direzione inversa della colonna (con cautela!)
✓ Per ritenzione <1 min — abbassare il % B, MeOH al posto di ACN
✓ Controllare la tabella "expected_rt" in wp_molgod_hplc_methods
Pressione troppo alta (pressure too high) critical
Sintomo: Pressione della pompa > 80% del massimo della colonna o shutdown del sistema con errore high-pressure
🔍 Albero diagnostico:
1. Controllare che la colonna sia collegata correttamente (direzione della freccia) → SÌ: OK → NO: Colonna invertita → invertirla (non lavorare mai "al contrario")
2. Test: rimuovere la colonna dal sistema, far girare pompa+rivelatore da soli → SÌ: La pressione scende a <50 bar → problema nella colonna (intasata) → NO: La pressione rimane alta → filtro in-line intasato, frit sporco
3. Controllare il filtro pre-colonna (frit in-line) → SÌ: Sporco e brunastro → sostituire → NO: Continue
4. Retro-lavare la colonna con ACN:H2O 50:50 senza la colonna — scompare? → SÌ: Particelle bloccate nel primo mm — un flush di 30 min può recuperarla → NO: Sostituire la colonna
⚠️ Cause comuni:
Filtro in-line (frit) intasato da particelle
Salting-out del buffer (precipitazione ad alto %B)
Il campione contiene materiale in sospensione (filtrare a 0.22 µm prima dell'iniezione)
Colonna intasata (compattazione del letto della colonna)
Gradiente con fase buffer + molto organico → precipitazione del sale
✓ Soluzioni:
✓ Filtrare SEMPRE il campione con PVDF 0.22 µm prima dell'iniezione
✓ Sostituire il filtro in-line ogni 100 iniezioni (o quando la pressione aumenta >20%)
✓ NON usare buffer fosfato >20mM + >70% ACN (il sale precipita)
✓ Lavare la colonna per 30 min con ACN:H2O 50:50 in direzione inversa (quando il produttore lo consente)
✓ Pre-colonna 4×3mm per proteggere la colonna principale
Picchi fantasma (ghost peaks) high
Sintomo: Picchi inspiegabili sul cromatogramma assenti nella calibrazione
🔍 Albero diagnostico:
1. Test: iniezione in bianco (solvente puro del campione) → SÌ: Compare un ghost → contaminazione del sistema o degli eluenti → NO: Compare solo con il campione → matrice
2. Il ghost cresce con il gradiente (eluisce ad alta %B)? → SÌ: Sì → colonna sovraccarica o composti fortemente trattenuti dalla corsa precedente → NO: Indipendente dal gradiente → carryover dell'autocampionatore
3. Increase carryover wash (between injections) → SÌ: Aiuta → il carryover era la causa. Protocollo di lavaggio più forte. → NO: Continue
4. Iniezione di acqua pura — c'è un picco? → SÌ: Sì → contaminazione della fonte d'acqua (sostanze organiche dal sistema DI) → NO: Continue
⚠️ Cause comuni:
Carryover nell'ago/loop dell'autocampionatore
Contaminazione dell'eluente (anche di grado HPLC)
Componenti fortemente trattenuti da corse precedenti
Plastica nelle fiale (ftalati, PEG dai tappi)
Acqua DI insufficientemente purificata
✓ Soluzioni:

❓ 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).

⚠️ Interakcje lekowe (1)MolGod_DRUGINT_1
Znane interakcje farmakokinetyczne i farmakodynamiczne dla CAS 67-68-5 wg konsensusowych źródeł klinicznych. Niniejsze informacje są edukacyjne — nie zastępują konsultacji lekarskiej.
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.
