Comparison of the composition of Pinus radiata bark extracts obtained at bench- and pilot-scales

Pine bark represents an interesting byproduct from the forest that can be used as a source of antioxidants. To study the phenolic fraction of this matrix, Pinus radiata bark was extracted with a 75% ethanol solution at both bench- and pilot-scales followed by an analysis of the extraction yield variation, chemical composition (total phenolics content, tannins content, and phenol composition determined by RP-HPLC–DAD–MS and GPC) and antioxidant...
