D-Pinitol (lD-3-O-methyl-cA/ro-inositol) is the most widely distributed inositol ether. It has been found in six gymnosperm families and 13 angiosperm families (137). In gymnosperms, it is a component of the resin of Pinus lamber-tiana (see 137) the bark of Picea abies, Pinus nigra (71), Pinus halepensis, and Schinus molle (72) (where its content has been determined as a function of season) the cambial sap of Pinus silvestris, Picea abies, and Abies alba (114) and the wood of Pinus spp. (see 6, 137) and Sequoia sempervirens (153). It also occurs in various plant parts, including latex and wood Acacia mollissima), of angio-sperms (see 137). 

Dihydroflavonols, which have different substituents at both C-2 and C-3, can exist in both cis- and trans-iovm >, (-h)-Dihydroquercetin (25), has been established to have the IR-. iR stereochemistry and the majority of other flavanonols that have been studied also possess this configuration. However, a few dihydroflavonols have been isolated in different optically active forms. Notably, both (-h)-fustin (26a) and (-)-fustin (26b) are known, the first occurring in Acacia mollissima heartwood and the second in Rhus cotinus wood. These compounds have opposite configurations.

No wax emulsion was added to the board to avoid the introduction of another factor that could have limited formaldehyde emission. To this glue mix were added 2 %, 5 % and 10 % UF resin solids by mass of commercial mimosa (wattle, Acacia mearnsii formerly mollissima) bark extract, a commercial flavonoid-type tannin extract.
