Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
and HPLC- DAD [4]. These methods are very efficient but slow, expensive and require a thorough sample preparation. Furthermore, they require trained personnel, and aren’t ecological [4,5] and they are ...
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 ...
Chemical and toxciological characterization of e-liquid cigarettes
methods were developed for the quantitative determination of nicotine and its related impurities (HPLC- DAD) and for the flavours diacetyl and acetylpropionyl (HS / GC- MS). Also, screening methods were ...
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 ...
Arsenic Speciation Analysis Elucidates the Risk Assesment of Food Supplements with Ingredients of Marine Origin. 9th Nordic Conference on plasma spectrochemistry
toxicity, such as arsenosugars and arsenolipids which can occur in marine matrices, in particular in algae. Analysis of As i in algae by HPLC- ICP- MS is complicated by the presence of arsenosugars in these ...
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 ...
