Silybin and silymarin--new effects and applications.

This article aims to review critically literature published mainly within this millennium on the new and emerging applications of silymarin, the polyphenolic fraction from the seeds of Silybum marianum and its main component silybin. Silymarin and silybin used so far mostly as hepatoprotectants were shown to have other interesting activities as e.g., anticancer and canceroprotective. These acti...

Evaluation of selected food supplements containing antioxidants.

Seven commercial food supplements present on the Polish market were evaluated for their in vitro antioxidant capacity. The selected products were in the form of hard gelatin capsules. They contained the extracts from chokeberry, cranberry, blueberry and green tea. The mixture of vitamins and minerals as well as the product containing vitamin C in substantial dose were included into comparison. ...

Determination of the cyanobacterial toxin cylindrospermopsin in algal food supplements

For the analysis of blue-green algal food supplements for cylindrospermopsin (CYN), a C18 solid-phase extraction column and a polygraphitized carbon solid-phase extraction column in series was an effective procedure for the clean-up of extracts. Determination of CYN was by liquid chromatography with ultraviolet light detection. At extract spiking levels of CYN equivalent to 25-500 µg g(-1), blu...

Comparative Investigation of Food Supplements Containing Ascorbic Acid

A simple, specific, precise and accurate reversed phase liquid chromatographic (RP-LC) method has been developed for the determination of ascorbic acid in different food additives. The chromatographic separation was achieved on a LiChrosorb C18, 250 mm x 4.6 mm, 5 μm column at a detector wavelength of 230 nm and a flow rate of 1.5 ml/min. The mobile phase was composed of acetonitrile and water ...
