“…v-hydroxyacids,18-hydroxy-9,12-octadienoic and 18-hydroxy-9-octadecenoic acids. The expected compositional variability of waxes from different provenances was clearly shown 95 but there were also significant changes in wax composition during industrial processing, 96 particularly in the period after boiling.…”

Cork is a natural, renewable, sustainable raw material that has been used for many centuries. As a result of this very long term interest, the scientific literature on cork is extensive. The present review focuses on the chemical composition, physical and mechanical properties of cork and on its products and sub-products. The substantial efforts to fully characterise cork, as well as new developments and evolving research, are reviewed, beginning with its histology, growth and morphology (at macro-and microscales). The chemical structure is analysed in detail, covering both the materials that form the wall structure and the low molecular weight, extractable components. The unique properties of cork are discussed and correlated with current knowledge on morphology and chemical structure. Finally, the important industrial applications of cork are reviewed, in the context of research to provide cork with novel, high added-value applications.

“…In general, evergreen trees supply soil with considerably more organic material than shrubs, so as it was expected, we found the highest water repellent samples and total SOM content under the tree species studied (Pinus and Quercus). Severe soil WR can be induced by a high number of phenolic compounds found in the composition of leaves and plant tissues of oaks (Conde et al, 1998;Salminen et al, 2004) and resins, waxes, aromatic oils, and other substances in pines (Doerr et al, 1998).…”

Biological and chemical factors controlling the patchy distribution of soil water repellency among plant species in a Mediterranean semiarid forest

et al. 2013

Natural soil water repellency is a property that has already been observed in forest soils and is characterized by its patchydistribution. Ihere are many factors involved in its development. In this work, we have studied a large numberof chemical and biological factors underthe influence of differentplantspecies (Pinus halepensis, Quercus rotundifolia, Cistus albidus and Rosmarinus officinalis) to leam which has the greatest responsibility for its presence and persistence in the top-soillayer. We obselVed strong and significant correlations between ergosterol, giomalin related soil protein (GRSP), extractable lipids, soil organic matter (SOM) content and water repellency (WR). Our results suggested lipid fraction as the principal factor. Moreover, apart from Pinus, fungal biomass seems to be also related to the SOM content. Soil WR found under Pinus appears to be the most influenced by fungi. Quality of SOM, to be precise, lipid fraction could be responsible for WR and its relationship with fungal activity.

“…[42] In contrast, some minor components such as polyphenols have shown this behavior. [43] A comparative study between the chemical composition of cork and NIRS spectra would be needed to confirm the hypotheses on the relationship between the chemical composition of cork and its geographical origin.…”
