The triacylglycerol (TAG) structure and the regio-stereospecific distribution of fatty acids (FA) of seed oils from most of the Apiaceae family are not well documented. The TAG structure ultimately determines the final physical properties of the oils and the position of FAs in the TAG molecule affects the digestion; absorption and metabolism; and physical and technological properties of TAGs. F...

The effect of spray drying on the different polyphenolic compounds present in root a purple-fleshed sweet potato variety Ipomoea batatas native from Peru was performed by HPLC-QTOF-MSMS. Nine anthocyanins, including four peonidin, three cyanidin and two pelargonidin derivatives glycosylated with sophorose and/or glucose acylated caffeic, ferulic p-hydroxybenzoic acid were identified. Twenty nin...

The metabolic profile of BAL4815, an antifungal azole drug, was determined using in vitro rat hepatocyte incubations and subsequent analysis by capillary LC-qTof-MS and MS/MS including accurate mass determination. For the detection of the metabolites, a mixture of the drug and its deuterium-labelled analogue was used for incubations. Metabolic stability of BAL4815 was high in cultured rat hepat...

Abdominal aortic aneurysm (AAA) is a permanent and localized aortic dilation, defined as aortic diameter ≥3 cm. It is an asymptomatic but potentially fatal condition because progressive enlargement of the abdominal aorta is spontaneously evolving towards rupture.Biomarkers may help to explain pathological processes of AAA expansion, and allow us to find novel therapeutic strategies or to determ...

This publication reports analytical properties of a new hallucinogenic substance identified in blotter papers seized from the drug market, namely 25C-NBOMe [2-(4-chloro-2,5-dimethoxyphenyl)-N-(2-methoxybenzyl)ethanamine]. The identification was based on results of comprehensive study including several analytical methods, i.e., GC-EI-MS (without derivatization and after derivatization with TFAA)...

Identification of bacterial isolates Tumpang and Bumiasri (East Java, Indonesia) using 16S rRNA gene sequencing screening their active compounds as a biofertilizer. Biodiversitas 24: 3338-3343. The objective the study was to identify (TPG) (BAS) screen-on biofertilizer active-compounds. Research materials us...

Considerable efforts are being made worldwide to replace in vivo assays with instrumental methods of analysis for the monitoring of marine biotoxins in shellfish. Analysis of these compounds by the preferred technique of LC-MS/MS is challenged by matrix effects associated with shellfish tissue components. In methods validation, assessment of matrix interferences is imperative to ensure the accu...
