The research aims to indicate which of the structural elements monoterpenes are responsible for their antioxidant activity. activity was determined spectrophotometrically with use DPPH• assay. It has been shown that π bonds chain-breaking monoterpenes. proved, first time, blocking conjugated double leads a decrease A probable reaction mechanism between and proposed. indicated strongly depends on polarity solvent used in experiments. presented results may stimulate additional field terpenoid...
Abstract Alzheimer’s disease (AD) is by far the most prevalent of all known forms dementia. Despite wide-spread research, main causes emergence and development AD have not been fully recognized. Natural, low-molecular, lipophilic terpenoids constitute an interesting group secondary plant metabolites, that exert biological activities possible use in prevention treatment AD. In order to identify metabolites possessing both antioxidant activity potential increase level acetylcholine, selected...
Alkaloids have protective functions for plants and can play an important role in living organisms. may a wide range of pharmacological activities. Many them cytotoxic activity. Nowadays, cancer has become serious public health problem. Searching effective drugs with anticancer activity is one the most significant challenges modern scientific research. The aim this study was investigation extracts obtained from Corydalis lutea root herb, Dicentra spectabilis Fumaria officinalis, Macleaya...
Abstract This research aims to investigate synergistic and antagonistic antioxidant interactions for binary mixtures of common monoterpenes. The activity was determined spectrophotometrically with the use DPPH • assay. Significant synergism, between two different monoterpenes, observed a mixture inactive p ‐cymene one compounds, characterized by moderate activity, e.g. (±)‐citronellal, α ‐phellandrene or ‐terpinene. It has been proven that (±)‐citronellal is increased in presence...
Optimal conditions for the extraction and analysis of furanocoumarins from fruits Archangelica officinalis Hoffm. have been determined. The following methods were used: exhaustive in a Soxhlet apparatus, ultrasonication at 25 60 degrees C, microwave-assisted solvent open closed systems, accelerated (ASE). In most cases yields highest using ASE method. effects extracting solvent, temperature time this method investigated. yield by was obtained with methanol 100-130 C 10 min. plant material an...
Twenty species of Salvia, naturally grown or cultivated in Poland, are investigated by headspace gas chromatography-mass spectrometry analysis. The main components the volatile fraction Salvia identified as a-pinene, camphene, β-pinene, thujol, camphor, β-chamigrene, and cadina-3,9-diene. There also compounds that can be considered chemotaxonomic markers, namely β-myrcene for lavadulifolia, β-phelandrene verticillata, τ-terpinene stepposa, isocaryophyllene caryophyllene officinalis. Certain...
Prohealth food contains specific components which have positive influence on the health and well-being of consumer. An important position among bioactive compounds occurs for polyphenols. Many results indicated that an increased intake phenolic may reduce risk cardiovascular diseases type 2 diabetes. The objective study was production extruded corn snacks with addition (0, 2, 4, 6, 8%) kale ( Brassica oleracea L. var. sabellica )—a polyphenol-rich plant. Afterwards, high-performance liquid...
The extracts of seven Lavandulae species (Lavandula stoechas, Lavandula lanata, viridis, angustifolia "Rosea", "Afropurpurea", and one unknown) were analyzed using the reversed-phase-high performance liquid chromatography–diode array detection (RP-HPLC–DAD) with gradient elution technique to obtain chromatographic fingerprint profiles. HPLC analysis was performed Kinetex RP18 column eluent consisting methanol-water-0.1% formic acid (5–100% (v/v)) at 30 °C run time 60 min. wavelength 280 nm....
Goji fruit (Lycium barbarum L.) has been identified as a polyphenolic compound plant source of noted richness. It also contains polysaccharides, carotenoids, vitamins and minerals, fatty organic acids. The purpose the presented research was to produce innovative instant corn gruels with various dry goji berry contents (1, 3 5%), determine level included compounds (including individual free phenolic acids) assess antioxidant properties these functional-food products. A further objective...
