Dihydrocuminic alcohol

An alcohol of the formula Cj Hj O was isolated from oil of ginger-grass by Schimmel Co., and described by them as dihydrocuminic alcohol. It has, however, now been shown by Semmler and Zaar not to have the constitution assigned to it by Schimmel Co., but to be identical with the alcohol obtained by reducing perillic aldehyde, Cj<,H 40, the aldehyde characteristic of the essential oil of PerUla nankinensis. 

The oil has been exhaustively examined by E. R. Miller, who finds the following substances present therein d-o-pinene, i -a-pinene, p-cymene, one or two unidentified terpenes, butyric aldehyde, iso-valeric aldehyde, a third aldehyde, possibly piperonal, carvacrol, thymoquinone, hydro-thymoquinone, dihydroxy-thymoquinone, dihydrocuminic alcohol, an unidentified alcohol, acetic acid, butyric acid, valeric acid, caproic acid, basic substances, and (in the aqueous distillate) acetone, formaldehyde, methyl alcohol, formic acid, and acetic acid.
