The HPLC analysis of polyphenolic compounds extracted from seed coats of coloured and white beans as well as definition of antioxidant properties of the obtained extracts constituted the purpose of the hereof elaboration. The materials for the research were obtained by extraction of the polyphenols with 0.5% HCl solution in methanol, vacuum concentration and lyophilisation. In the research, defractioning...
The objective of this work was to use the fluorometric method to study the antioxidative properties of the preparations obtained from the seed coats of red and brown beans. The preparations were obtained by extraction of the polyphenols with 0.5% HCl solution in methanol, vacuum concentration and lyophilisation. The qualitative and quantitative compositions of the preparations were determined. The...
