Bupleurum rigidum is a perennial plant (Hemicryptophyte) showing a West-Mediterranean distribution. This species is abundant in open zones of holm-oak (Quercus ilex subsp. ballota) and hermes-oak (Quercus coccifera) xerofitic woods and gall-oak (Quercus faginea) mesoxerofitic...

Local emissions from specific plants were investigated by Holzinger et al. who have identified methanol, acetaldehyde, ethanol, acetone, acetic acid, isoprene, monoterpenes, toluene, and Cio-benzenes emitted from the Mediterranean helm oak (Quercus ilex L.) [36]. After flooding, ethanol and acetaldehyde were found to increase, indicating ethanol production under anoxic condition of the root system and the subsequent transport and partial oxidation to acetaldehyde inside the green leaves. Additionally, bursts of acetaldehyde with lower ethanol emission were also found in the case of the fast light/dark changes. The rapid formation of acet-...

It has been reported that the major aliphatic monomers of suberin polymers from several tree barks are fatty acids with both a>- and mid-chain oxygenation (192). These monomers include 9,10-epoxy-18-hydroxyoctadecanoic acid and 9,10,18-trihydroxyoctadecanoic acid, both of which are common components of cutin polymers (232). For example, 9,10-epoxy-18-hydroxyoctadecanoic acid was reported to be the major monomer (31%) of Quercus ilex bark suberin and... 

Kermococcus illicis L. (formerly Coccus illicis L.), which is found on the oak Quercus ilex L. in the Mediterranean region, is mentioned in the historical Hterature as a source of kermes however, it appears that it is not possible to derive a dyesmff from this insect (Schweppe, 1992) and Cardon (1990) posmlates that this may have been used as a substitution product, as she indicated that it produces a poor dye of hrown-red colour.
