EXTRACTION OF POLYFLAVONOIDS FROM Pinus radiata D. Don BARK: EVALUATION OF EFFECTS OF SOLVENT COMPOSITION AND OF THE HEIGHT ON TREE BARK

This work evaluates the effect of the composition of the solvent mixture on the extraction of polyflavonoids from the bark of Pinus radiata. Non-reactive solvent systems were selected, specifically water 100%, methanol 100 %, and mixtures of them in proportions (7:3), (1:1) and (3:7). The amounts of...
