Sapwood samples of Scots pine (P. sylvestris L., Pinaceae), Pitch pine (Pinus rigida Mill., Pinaceae), and European beech (F. sylvatica L.) (Fagaceae), were provided from a woodworking shop in Alexandria City, Egypt, August 2014. The wood samples (10 × 10 × 5 mm) were oven-dried at 105 °C for 24 h, then autoclaved at 121 °C for 20 min.

Evaluation of the antioxidant activity of the investigated EOs was achieved using 2 methods to reveal their antioxidant potential. All EOs showed a potent antioxidant activity, especially the JOF EO with an IC 50 value of 20.2 ± 1.0 mg/mL via DPPH scavenging, due certainly to the chemical composition of each EO and to the synergy between the ...

Natural compounds for wood protection against fungi - all natural substances (or their mixtures) of plant or animal origin with proven antifungal activity and possibility to be applied into wood structure or on its surface to protect wood against wood decaying fungi, blue stain and mold, e.g. essential oils, tannins, wood extractives, alkaloids, propolis or chitosan.

The cone and sharp of pitch pine are thick and rigid, making this a distinctive and easy-to-remember . In New England, it most commonly occurs in sandy barrens and coastal plains; it is the only moderately salt-tolerant pine in the region. It relies on fire to clear areas of competitors and allow for colonization.
