Determination of Flavonoids, Tannins and Ellagic acid in leaves fromRubus L. species

This paper describes the quantitative determination of flavonoids, tannins and ellagic acid in the leaves from wild and cultivated variations ofRubus L. species (Rosaceae): raspberry (2 wild and 13 cultivars) and blackberry (3 wild and 3 cultivars). The content of flavonoids was analyzed using spectrophotometric (the Christ-Mullers method) and HPLC analysis after acid hydrolysis. The content of tannins was determined by the weight method, with...
