Screening the capability of vibrational spectroscopic techniques for simultaneous quantification of vitamins B1, B6, and B12 in a powder blend
well as to monitor the powder blend homogeneity. Results from each of the vibrational spectroscopy techniques were compared with those obtained by HPLC, which served as the reference analytical technique ...
European fingerprint study on omeprazole drug substances using a multi analytical approach and chemometrics as a tool for the discrimination of manufacturing sources
analysis carried out by 7 European laboratories on 28 samples from 11 manufacturers with 5 analytical techniques (related substances with HPLC, residual solvents with GC- MS, near infrared spectroscopy, ...
Does arsenic pose a health concern after consumption of clay products?
38, Issue 1, Number 124 (2021) Keywords: Arsenic Dietary Supplements heavy metals HPLC ICP-MS Abstract: Clay products for oral use form a particular group of food supplements in relation to potential ...
In vitro antigenotoxic activity, in silico ADME prediction and protective effects against aflatoxin B1 induced hepatotoxicity in rats of an Erythrina latissima stem bark extract
stem bark extracts (ELBE) may counteract the in vivo hepatotoxic effects of aflatoxins, contaminants in food and feed. An HPLC- DAD method was developed and validated to determine the level of flavonoid ...
A comparative study on chemical composition, antibiofilm and biological activities of leaves extracts of four Tunisian olive cultivars
‘Oueslati’ and ‘Jarboui’. By means of standardized methods, total phenols were determined and some of them characterized by HPLC. The total phenols and flavonoids contents were found to be the highest in the ...
Identification of a new tert-leucinate class synthetic cannabinoid in powder and "spice-like" herbal incenses: Methyl 2-[[1-(5-fluoropentyl)indole-3-carbonyl]amino]-3,3-dimethyl-butanoate (5F-MDMB-PICA).
chromatography with diode array detector (HPLC- PDA) and gas chromatography mass spectrometry (GC- MS) with computer based library search against spectral libraries. However, the most predominant compound in the ...
Chromatographic fingerprinting as a strategy to identify regulated plants in illegal herbal supplements.
explore the potential use of chromatographic fingerprinting to identify plants present in herbal preparations intended for the treatment of ED. To achieve this goal, a HPLC- PDA and a HPLC- MS method were ...
Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
is a very important topic. During this study a High Performance Liquid Chromatography-Photodiode Array (HPLC- PDA) and a High Performance Liquid Chromatography — Mass Spectrometry (HPLC- MS) method ...
Testing of complementarity of PDA and MS detectors using chromatographic fingerprinting of genuine and counterfeit samples containing sildenafil citrate.
a very important issue. In this study, a high-performance liquid chromatography-photodiode array (HPLC- PDA) and high-performance liquid chromatography-mass spectrometry (HPLC- MS) method were developed ...
Dietary intake of lycopene by the Belgian adult population.
assessment. Determination of the lycopene content in foods was performed with HPLC- UV. Individual food consumption data were multiplied by the actual mean concentrations of lycopene per food. SUBJECTS: ...
