Pinus radiata bark showed the highest polyphenol content and potent antioxidant activity. Pinus rigida bark was also a usable polyphenol-rich source, whereas Pinus densifl ora bark had a low yield (5.1%) of hot water extract, although it showed potent antioxidant activity. Correlations between proanthocyanidin content in pine bark and ...

In this study, physicochemical characteristics, phytochemical compositions, and antioxidant activities of Pinus halepensis Mill. seed oils (PHSO) from two geographical origins (Algeria and Turkey) and obtained through two different extraction processes (cold pressing and solvent extraction) were determined. PHSO were majorly consisted of linoleic and oleic acids.
