“…Similar behavior was reported (Jerez et al 2007a) for plants and pine extracts (R 2 = 0.822). Thus, when an extract shows high antiradical activity, it also exhibits high reducing activity.…”

“…Multiple authors have reported the antioxidant bioactivity of pine bark extract (Jerez et al 2006, Ku et al 2007, Cortés et al 2010, Dudonné et al 2009). In comparison with other pine species, Pinus radiata bark has shown the highest values for polyphenol content and antiradical activity (Jerez et al 2007a, Ku et al 2007). …”

“…The forest and paper industry generates large amounts of organic wastes of different compositions (Jerez et al 2007a), where pine bark generated in the production process of wood pulp for paper usually is combusted or wasted although several extractable compounds could be used as high value products. Multiple authors have reported the antioxidant bioactivity of pine bark extract (Jerez et al 2006, Ku et al 2007, Cortés et al 2010, Dudonné et al 2009).…”

“…Many studies of natural antioxidant extraction from pine (Jerez et al 2007a, Jerez et al 2006, Ku et al 2007, Jerez et al 2007b, grape Jones 2001, Kennedy andTaylor 2003), apple (Rupasinghe et al 2010) and plants (Heimler et al 2007, Romani et al 2006) have been performed, although most have been conducted on a laboratory scale. Indeed, Jerez et al (2006Jerez et al ( , 2007b, Ku et al (2007) and Diouf et al (2006) used 0.16 L reactors, 0.25 L extractors and 22 cm 3 cells, respectively;…”

Many pine bark extracts have antioxidant properties. This work examined bench scale extraction on the yield, the composition and antioxidant properties of Pinus radiata. Acetone solvent (98.7% w/w at 120 °C) yielded maximum phenols concentration, tannins concentration, anti-radical activity (DPPH) and reducing activity (FRAP), although its extraction yield was the lowest. When the organic solvent in the mixture decreased, the chelating activity increased (ICA) and antiradical and reducing activities decreased. The extract largest yield was obtained with water at 120ºC, but the antioxidant properties were relatively poor. Taxifolin (dihydroquercetin) and catechin were the main extract components detected by RP-HPLC. The best extraction conditions for high extractive yield and antioxidant properties was achieved with ethanol/water at 120 °C.

“…These extracts are constituted essentially with phenols, sugars and gums (Singleton 1974;Fengel & Wegener, 1984;Benlarbi et al, 1999;Ghanmi et al, 2005;Jerez et al, 2005;Ghanmi et al, 2007). Sugars are subdivided in two groups: free sugars reducers and combined sugars obtained after acid hydrolysis (Dutel & Achchoubi, 1983).…”
