Notes:
Isol. from cocoa butter and roots of Ruta graveolens (rue) 2,3-Butanediol is one of the constitutional isomers of butanediol. The 2R,3R stereoisomer of 2,3-butanediol is produced by a variety of microorganisms, in a process known as butanediol fermentation. It is found in cocoa butter and in the roots of Ruta graveolens.
