Screening of radical scavenging activity of some medicinaland aromatic plant extracts. Russ J Bioorg Chem 26 Preparative extraction of anthocyanins from plant materials Edyta Dutkiewicz Abstract Anthocyanins are one of the most common groups of dyes which are soluble in water.

Rhaponticum carthamoides Leuzea carthamoides is a Siberian endemic perennial used for centuries in folk medicine as a body-strengthening specimen based on alcohol extracts. Steroids 73 This file contains additional information such as Exif metadata which may have been added by the digital ko,umnowa, scanner, or software program used to create or digitize it. Photografic sequence of a cromatografic column.

Different water and methanol solutions, which were used to purify anthocyanins, were checked. Chem Nat Compd 33 The biggest challenge was to receive anthocyanins in solid form. Lipids 30 The object of this work is to collate and compare the most popular chromatographic techniques used in separation and determination of ecdysteroids in plant material of Rhaponticum carthamoides. By using HPLC with appropriate detectors it is also possible to identify separate anthocyanins. Chromatographia 52 From Wikimedia Commons, the free media repository.

Susceptibility of some clinical isolates of Staphylococcus aureus to fractions from the aerial parts of Leuzea carthamoides. They are responsible for red, blue and violet colour of flowers, leaves and fruits. Choosing a resin was important.

The basic structure of anthocyanins is flavylium ion, to which saccharide residues are often added.
