Quercus genera

Quercitol is a deoxyinositol (1,3,4/2,5-cyclohexanepentol) which appears in certain Dicotyledons including all the Quercus genus (Plouvier 1963). This compound has been found in wines aged in contact with oak wood (barrels or chips) but not in wines aged in bottles (Carlavilla et al. 2006). 

We have today a better understanding of the composition of oak of various origins. Oak is a naturally aromatic wood. This is largely due to the presence of a highly aromatic lactone, fi-methyl- -octalactone [1], which is specific to the Quercus genus... 

As yet, only the (+)-proproto-quercitol (IS) is present in all of 33 species of the genus Quercus examined, and it seems to be present in every part of the tree. Nineteen plant species from eight other botanical families also contain profo-querci-tol. ... 

We will try to solve this riddle because it provides us with a unique insight into the fractal nature of hermetic drift. Fulcanelli suggested that we focus on the gall apples on the leaves of the oak. The Apple tree or Quert is associated with the Oak and the Oak is of the genus Quercus and generally linked with the God Q re. 

Tannins involving (—)-shikimic acid (12), quinic acid (13), 5cy//o-quercitol (14), and proto-quercitol (15) (Fig. 12.1) cores are known. Most of the unusual types that have been studied are from the genus Quercus (oaks) and other members of the family Fagaceae (Porter, 1989). 

D-Quercitol (73) is common in members of the genus Quercus, oaks, of the family Fagaceae. This cyclitol derivative is known from at least nine other families. D-Pinitol (63) is known from six families of gymnosperms, in which it is widespread, but it is also known from a number of angio-sperms.
