Spektren werden bei Bedarf aus 9 Quellen abgerufen. Jedes Spektrum wird in unserer Datenbank gespeichert — beim nächsten Öffnen erfolgt keine Anfrage an die externe API. Laden Sie JCAMP-DX / CSV / PNG zu jedem Spektrum herunter, ohne zu suchen.
Daten werden über MolGod_Spectra_Remote_Fetcher (JCAMP-DX-Parser) abgerufen und in der Tabelle wp_molgod_spectra_cache gespeichert. Keine doppelten Downloads, keine erneuten Anfragen an NIST bei späteren Aufrufen. Lizenzen werden eingehalten (veröffentlicht wird nur ein Deep-Link plus eigene Visualisierung).
Daten werden live aus mehreren Quellen abgerufen (Priority-Chain). JCAMP-DX / CSV / PNG stehen unter jedem Spektrum zum Download bereit. ⓘ Eine Quelle ★★☆☆☆ⓘ Eine Quelle ★★☆☆☆

Gastrodia elata Blume (Tianma in Chinese), a myco-heterotrophic orchid, is widely distributed in China. Tubers derived from this orchid are traditionally used as both medicinal and edible materials. At present, five primary varieties of G. elata are recorded in the “Flora of China.” Among them, the three main varieties currently in artificial cultivation are G. elata f. elata (GR, red stem), G. elata f. glauca (GB, black stem), and G. elata f. viridis (GG, green stem). In our study, the metabolic profiles and chemical composition of these three varieties were determined via UPLC-MS/MS and HPLC-UV. In total, 11,132 metabolites were detected, from which multiple phytometabolites were identified as aromatic compounds, heteroatomic compounds, furans, carbohydrates, organic acids, and their derivatives. A number of differentially expressed metabolites (DEMs) were annotated as bioactive ingredients. Overall, parishins, vanilloloside, and gastrodin A/B in the GB group were markedly higher, whereas gastrodin, gastrol, and syringic acid were more enriched in the GG or GR groups. Moreover, HPLC fingerprint analysis also found six metabolites used as markers for the identification of Gastrodiae Rhizoma in the Chinese Pharmacopoeia, which were also typical DEMs in metabolomics. Of these, gastrodin, 4-hydroxybenzyl alcohol, citric acid, and adenosine were quantitatively detected, showing a similar result with the metabolomic data. In summary, our findings provide novel insights into the phytochemical ingredients of different G. elata varieties, highlighting diverse biological activities and healthcare value.

BMC Complementary and Alternative Medicine. 2018;18:307. doi:10.1186/s12906-018-2374-7
BackgroundThe phytochemical constituents and biological activities of Rosa rugosa Thunb. var. plena Regal flower cell sap (RFCS) were investigated.MethodsVolatile constituent, such as linalool, phenylethyl alcohol, citronellol, α-bisabolol, were identified by GC-MS. The contents of hyperoside, kaempferol-3-O-rutinosid, rutin, and luteolin as well as the total flavonoid content in RFCS were determined by HPLC and HPLC-MS. The total polyphenol content was evaluated by the Folin-Ciocalteu colorimetric method. The antioxidant activities of RFCS and the standards were evaluated by DPPH and ABTS radical scavenging assays. The tyrosinase inhibitory activities of the rose samples and standard substance were determined by a spectrophotometric method. The antimicrobial effects of RFCS were evaluated in terms of minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) or minimum Fungicidal concentrations (MFCs).ResultsThe rose fraction exhibited a high content of biologically active ingredients. The total content of volatile compounds in RFCS was approximately 48.21 ± 2.76 ng/mL. The total phenolic acid content and total flavonoid content were 0.31 ± 0.01 mg/mL and 0.43 ± 0.01 mg/mL, respectively. Its IC50 value in the DPPH assay was 1120 ± 42 μg/mL, and its IC50 value for ABTS radical scavenging activity was 1430 ± 42 μg/mL.RFCS strongly inhibited L-tyrosine oxidation with an IC50 value of 570 ± 21 μg/mL. Every compound identified in RFCS exhibited broad-spectrum antimicrobial activity. F. nucleatum was most susceptible to RFCS with an MIC of 64 μg/mL and MBC of 250 μg/mL.ConclusionsDue to its rose-like aroma, phenylethyl alcohol may be combined with linalool for use as a natural skin-whitening agent and skin care additive in the and pharmaceutical industries.

Qu L, Song K, Zhang Q, Guo J, Huang J. Simultaneous Determination of Six Isoflavones from Puerariae Lobatae Radix by CPE-HPLC and Effect of Puerarin on Tyrosinase Activity. Molecules. 2020;25:344. doi:10.3390/molecules25020344
Tyrosinase inhibitors with excellent inhibitory activities and lower side effects have promising applications in the fields of medicine, agriculture, food sciences and cosmetics. In this study, a method for simultaneous separation and determination of six target compounds (puerarin, daidzin, genistein, daidzein, genistin, and formononetin) in Puerariae Lobatae Radix was established by cloud point extraction (CPE) and concentration combined with high performance liquid chromatography (HPLC). To achieve high extraction yields, an ultrasound-assisted extraction method was developed based on a salt-modified Triton X-100 system. The optimal extraction conditions are: surfactant Triton X-100 concentration 0.07 g/mL, liquid-solid ratio 80:1 (mL/g), NaCl addition amount 0.6 g, equilibrium time 40 min, equilibrium temperature 70 °C. Under the optimal conditions, the total maximum extraction yield of the six target isoflavones reached 8.92 mg/g. Using l-tyrosine and l-dopa as substrates, the effects of puerarin on the monophenolase and diphenolase activity of tyrosinase activity were investigated by the enzyme kinetics method. The results showed that puerarin inhibited monophenolase activity with an IC50 of 0.537 mg/mL and activated diphenolase activity. The inhibition type of puerarin on monophenolase and the activation type of puerarin on diphenolase were analyzed by Lineweaver-Burk plots which show that puerarin showed mixed inhibition on monophenolase and mixed activation on diphenolase. Therefore, puerarin can be used as both a tyrosinase inhibitor and a tyrosinase activator.

❓ Jak przygotować roztwór standardowy L-Tyrosine o stężeniu 1 mg/mL?
MolGod_TECHFAQ_1_Q0
Aby przygotować roztwór standardowy L-Tyrosine (CAS 60-18-4) o stężeniu 1 mg/mL, należy odważyć 1 mg substancji (co odpowiada 1/181.19 g, czyli około 0.00552 g) i rozpuścić w 1 mL rozpuszczalnika, np. wody dejonizowanej lub buforu fosforanowego pH 7.4. Masa molowa L-Tyrosine wynosi 181.19 g/mol, więc 1 mg to 1/181.19 mmol.

❓ Jak przechowywać L-Tyrosine, aby zachować jego stabilność?
MolGod_TECHFAQ_1_Q1
L-Tyrosine należy przechowywać w temperaturze 2-8°C, chroniąc przed światłem (w nieprzezroczystym pojemniku) i wilgocią. Optymalne warunki to chłodna, ciemna i sucha przestrzeń, np. lodówka laboratoryjna z kontrolą wilgotności.

❓ Jaka metoda analityczna jest najlepsza do oznaczania czystości L-Tyrosine?
MolGod_TECHFAQ_1_Q2
Dla L-Tyrosine (MW 181.19 g/mol, logP nieznany) zalecana jest wysokosprawna chromatografia cieczowa (HPLC) z detektorem UV (np. przy 254 nm) lub spektrometrią mas (MS). Jeśli logP jest niski, HPLC jest optymalna; jeśli wysoki - można rozważyć GC po odpowiedniej derywatyzacji.
Hilfreich?
❓ Jakie reakcje uboczne mogą wystąpić podczas syntezy lub oczyszczania L-Tyrosine?
MolGod_TECHFAQ_1_Q3
L-Tyrosine może ulegać hydrolizie w środowisku kwaśnym/zasadowym, utlenieniu (np. do kwasu 4-hydroksybenzoesowego) lub racemizacji. Należy unikać kontaktu z silnymi utleniaczami (np. H2O2), mocnymi kwasami/zasadami oraz wysokich temperatur podczas oczyszczania.

❓ W jakim celu stosuje się L-Tyrosine w laboratoriach badawczych?
MolGod_TECHFAQ_1_Q4
L-Tyrosine jest używana jako substrat w syntezie peptydów i białek, do badań szlaków metabolicznych (np. syntezy katecholamin), oraz jako standard w analizie aminokwasów. Wymaga precyzyjnego dawkowania ze względu na niską masę cząsteczkową i wrażliwość na warunki przechowywania.

Food industry: wykorzystywana jako składnik w żywności funkcjonalnej, np. napojach proteinowych czy batonikach energetycznych.
Chemical industry: może służyć do syntezy różnych chemikaliów i farmaceutyków.
Bezpieczeństwo
L-Tyrosine jest uważana za substancję stosunkowo bezpieczną, gdy stosowana zgodnie z zalecanymi dawkami. Należy jednak pamiętać o kilku wskazówkach BHP:
Przechowywanie: trzymać w szczelnie zamkniętym pojemniku, chronić przed światłem i wilgocią. Unikać kontaktu z oczami i skórą.
Ryzyko reakcji ubocznych: spożycie dużych ilości L-Tyrosine może wywołać objawy takie jak nudności, wymioty czy biegunka. W przypadku stosowania w preparatach farmaceutycznych, należy przestrzegać zalecanych dawek i skonsultować się z lekarzem przed użyciem.
Przechowywanie
L-Tyrosine powinna być przechowywana w suchym, chłodnym i dobrze wentylowanym pomieszczeniu. Optymalne warunki to temperatura od 2°C do 8°C. Przechowywać z dala od bezpośredniego światła słonecznego i ź
