Ibuprofen as an Organic Pollutant in the Danube and Effects on Aquatic Organisms.

The presence of emerging substances in surface water is of a great concern knowing they are the main source for community water supply needs. This study describes the development, optimization and application of an analytical method for the determination of ibuprofen in the Danube samples. Caffeine concentrations, as an indicator of human waste, were determined and maximum risk indexes for aquatic organisms were calculated.

Synthesis and evolution of physicochemical properties of new pharmaceutically active ionic liquids - tetracainium salicylate and tetracainium ibuprofenate.

Tetracainium salicylate and tetracainium ibuprofenate were synthesized as active pharmaceutical ingredient ionic liquids (API-ILs). These ILs represent a combination of a drug for local anaesthesia (tetracaine) and nonsteroidal anti-inflammatory drugs (salicylic acid and ibuprofen). After IL synthesis, spectroscopic investigations were performed using infrared and nuclear magnetic resonance spectroscopy to confirm their structures.

Pharmacological effects of novel microvesicles of basil, on blood glucose and the lipid profile: a preclinical study.

Microencapsulation represents a process that can create targeted, controlled release kinetics of drugs, thus optimizing therapeutic efficacy. Our group has investigated the impact of this technology on Wistar rats to determine pharmacological efficacy of basil extracts. Animals were treated with water extract of Ocimum basilicum in microvesicles and with combination of basil extracts and 3α,7α-dihydroxy-12-keto-5-cholanate, also known as 12-monoketocholic acid (MKC) acid in microvesicles for 7 days.

Experimental and Computational Evaluation of Extraction Procedure and Scavenging Capacity of Sweet Basil Extracts (Ocimum basilicum L.).

The possibility to prevent nutrition-related diseases that include scavenge of free radicals and to block chain reactions is very important and significant for human well-being. The aim of this study was to analyse different basil extracts, determine the relationship between total phenolic/flavonoid content and antioxidant activity in order to optimize its application in industry. The extraction involved different solvents (ethanol, methanol and water), extraction time (10 and 30 min and 24, 48 and 72 h), plant fragmentation level (0.

Methodological Aspects of Extraction, Phytochemical Characterization and Molecular Docking Studies of Salix caprea L. Bark and Leaves.

Contents of twelve selected bioactive substances and antioxidant potential of Salix caprea L. extracts were compared in its two vegetative organs (bark and leaves) and in terms of different ethanol/water mixtures used for extraction (30-70% aq, ethanol) and extraction time (30 min; 24, 48 and 72 h). The extracts were characterized by High Pressure Liquid Chromatography (HPLC), and total phenolics and flavonoids were determined spectrophotometrically.

The occurrence of selected xenobiotics in the Danube river via LC-MS/MS.

Having in mind that there is a general lack of monitoring plans and precaution measures in the developing countries and that the Danube is the second longest river in Europe, the estimation of the relevant concentration levels of unregulated xenobiotics is a topic of interest both on local and international level. The selected pharmaceuticals, caffeine, and benzotriazole presented in the collected water samples from seven representative locations around the territory of Novi Sad, Serbia, during 1-year period, were analyzed with the use of solid-phase extraction followed by the liquid chromatography coupled with triple quad tandem mass spectrometry. The most frequently detected compounds were caffeine and carbamazepine in the concentrations up to 621 and 22.

Determination of 5-caffeoylquinic acid (5-CQA) as one of the major classes of chlorogenic acid in commercial tea and coffee samples.

Background/aim: Tea and coffee are one of the most widely consumed beverages in the world due to their beneficial health effects which are largely associated with their phenolic compounds composition, including chlorogenic acid. The main aim of this study was to determine 5-caffeoylquinic acid (5-CQA), as one of the major classes of chlorogenic acid, in various commercial tea and coffee samples present at the Serbian market.

Methods: A high-performance liquid chromatography (HPLC) method for determination of 5-CQA in plant extracts was applied to determine the content of this active compound in commercial tea and coffee samples.
