Total polyphenols, total anthocyanins and antioxidant activity of various berries: [aronia (Aronia melanocarpa), blackberry (Rubus fruticosus), red raspberry (Rubus idaeus), and strawberry (Fragaria anannassa)] have been evaluated in this study by using Folin-Ciocalteau, pH-diff erential, and DPPH method. Amount of anthocyanins ranged from 232 to 4341 mg kg-1 in strawberry and aronia, respectiv...

The aim of this work was to evaluate the antioxidant potential of teas prepared from twenty-four commercially available berries and flowers of Sambucus nigra L. in relation to their phenolic profile, as reflected by the most representative phenolic acids (caffeic, chlorogenic, p-coumaric, ferulic, gallic and syringic acids); flavonols (quercetin, kaempferol, myricetin and rutin); and total phen...

A free radical scavenging activity guided fractionation of the polar extract from roots of Limonium brasiliense (Plumbaginaceae) led to the isolation of five active compounds including: myricetin 3-O-alpha-rhamnopyranoside (1), (-)-epigallocatechin 3-O-gallate (2), (-)-epigallocatechin (3), (+)-gallocatechin (4) and gallic acid (5). These and other chemical constituents are reported for the fir...
