摘要：
In order to isolate polyphenols from Douglas fir outer bark, this latter was mechanically fractionated by means of knife and ball millings. The sieving of the resulting powder gave rise to a set of fractions with different particle sizes and shapes. The particles ranging from 0.56 to 0.16 mm size were mainly composed of tannins (46%) while, taxifolin was located in the coarser fraction (83%) with particles size above 1 mm. The isolated phenolic compounds are suitable of upgrading to higher value products. (C) 2016 Elsevier B.V. All rights reserved.
