This study evaluates the levels of total polyphenolic compounds in three Malian medicinal plants and determines their antioxidant potential. Quantitative and qualitative analysis of polyphenolics contained in plants extracts were carried out by RP-C18 RP-HPLC using UV detector. The antioxidant activity was determined by three tests. They are phosphomolybdenum, DPPH (2,2-diphenyl-1 picrylhydrazy...

THE blue colour of the blood of certain arthropods and molluscs is due to the presence of a protein, containing copper, which exists in oxidised and reduced forms; the former, oxyhaemocyanin, has a blue colour, whilst the latter, haemocyanin, is colourless. The transformation of the oxidised into the reduced form is readily accomplished by exposing blood containing oxyhaemocyanin to a vacuum or...

Research over the past decade has produced incontrovertible evidence for a vast array of health benefits arising from the consumption of fruits and vegetables. In an endeavor to identify the active health-promoting ingredients , many researchers have focused on the properties of the flavonoids, a large class of phenolic compounds that is abundant in such foods. Most prominent among the flavonoi...

cyanin formation have highlighted that multiple photoreceptors, such as phytochrome, blue/UV-A photoreceptor Although, in maize, sunlight-regulated anthocyanin and UV-B photoreceptor mediate the light action (Beggs formation in vegetative tissues is observed only in the and Wellmann, 1985; Beggs et al., 1986). It is assumed cultivars harbouring homozygous recessive pl loci, the that these photo...
