The terpene and fatty acid composition in ethanol extracts of spearmint (lat. Mentha spicata) growing the Middle Urals was studied by gas chromatography chromatography-mass spectrometry. qualitative quantitative fraction depending on part plant (leaves, stems, roots) storage method (freezing, drying). 30 components were found extracts, 24 identified. It that greatest amount terpenes is containe...

Novel primaquine conjugates with non-steroidal anti-inlammatory drugs (PQ-NSAIDs, 4a-h) were prepared, fully chemically characterized and screened for radical scavenging and antioxidant activities. The synthetic procedure leading to twin drugs 4a-h involved two steps: i) preparation of NSAID benzotriazolides 3a-h from the corresponding NSAID (ibuprofen, ketoprofen, fenoprofen, ketoprofen hydrox...

In vitro techniques are essential to assess the antioxidant potential of foods, although methods with different action mechanisms make troublesome data analysis. This article describes use artificial neural network (ANN) associate phenolic compounds activity in (AOX) grape juices. A multilayer perceptron (MLP) ANN was obtained 28 phenolics quantified, as input layers, and AOX measuring by DPPH,...

objectives: the objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of ligularia persica boiss (l. persica) growing wild in north of iran. materials and methods: essential oils were extracted by using clevenger-type apparatus. antibacterial activity was tested on two gram-positive and two gra...

The aim of this study was to evaluate the effect of the carotenoidic saponified extract of Physalis alkekengi sepals (PA) towards the lipoxygenase (LOX) oxidation of linoleic acid. Lipoxygenase activity in the presence of carotenoids, standard and from extract, was followed by its kinetic behaviour determining the changes in absorption at 234 nm. The standard carotenoids used were β-carotene (β...

In this study, antioxidant and antibacterial activities of various solvent extracts (methanol, ethanol, acetone and petroleum benzine) obtained from bulbs and leaves of Allium deciduum subsp. deciduum and subsp. retrorsum were investigated. Antioxidant activity of the extracts was determined by DPPH radical scavenging and β-carotene/linoleic acid assays. In addition, total phenolic contents in ...
