Phenolic compounds are well-known phytochemicals found in all plants. They consist of simple phenols, benzoic and cinnamic acid, coumarins, tannins, lignins, lignans and flavonoids. Substantial developments in research focused on the extraction, identification and quantification of phenolic compounds as medicinal and/or dietary molecules have occurred over the last 25 years. Organic solvent ext...

The consumption of a diet low in fat and enhanced by fruits and vegetables, especially rich in phenolic compounds, may reduce risks of many civilization diseases. The use of traditional medicines, mainly derived from plant sources, has become an attractive segment in the management of many lifestyle diseases. Concerning the application of dietary supplements (based on phenolic compounds) in com...

. In this paper content of phenolic compounds from black radish (Raphanus sativus L. var niger) roots of different size were examined. Black radish grown in Serbia, with the same period of development, grouped by size into three groups: (R1) with mass of 350 15 g; (R2): 100 10 g and (R3): 35 5 g, were used. Plant extracts were prepared by using 80% (v/v) ethanol and total phenolic compounds con...

Diets containing high proportions of fruits and vegetables reduce the risk of onset of chronic diseases. The role of herbal medicines in improving human health is gaining popularity over the years, which also increases the need for safety and efficiency of these products. Green leafy vegetables (GLVs) are the richest source of phenolic compounds with excellent antioxidant properties. Increased ...

The present work aims to assess the antibacterial potential of phenolic extracts, recovered from plants obtained on the North East of Portugal, and of their phenolic compounds (ellagic, caffeic, and gallic acids, quercetin, kaempferol, and rutin), against bacteria commonly found on skin infections. The disk diffusion and the susceptibility assays were used to identify the most active extracts a...

Blackcurrant leaves are an essential source of phenolic compounds and this study investigated their variation relative to leaf positions and harvest date. The phenolic content varied between harvest dates, although leaf position on the shoot and interactions also played an important role. The contents of quercetin-malonyl-glucoside, kaempferol-malonyl-glucoside isomer and kaempferol-malonyl-glu...

Propolis is a resinous hive product Kv bees. The versatile biological activities of propolis, such as its antibacterial, antiviral, fungicidal, anti­ ulcer, immunostimulating, hypotensive and cytosta­ tic properties, as well as its successful clinical applica­ tions [1 — 3] have created an increasing interest in its chemical composition. The last appears to be very complex — the bees collect pr...

The aim of this work was to establish the antioxidant capacity and the polyphenolic profile of Artemisia absinthium that could potentially be used in the human diet. An ultra-high performance liquid chromatographic method was used to identify and quantify individual phenolic compounds of the A. absinthium leaves. A total of 20 polyphenolic compounds were identified and quantified in A. absinthi...

BACKGROUND The aims of this study were to evaluate the antioxidant activity and to identify the antioxidant components of a traditional Chinese medicine formula consisting of a combination of Shanzha (the fruit of Crataegus pinnatifida Bge. var. major N.E.Br., SZ) and Danshen (the root of Salvia miltiorrhiza Bge., DS). This medicine is extensively used to treat cardiovascular disease. METHODS...

Interest in the development of bioprocesses for the production or extraction of bioactive compounds from natural sources has increased in recent years due to the potential applications of these compounds in food, chemical, and pharmaceutical industries. In this context, solid-state fermentation (SSF) has received great attention because this bioprocess has potential to successfully convert inex...
