The Essential Oils of <i>Hedeoma mandoniana</i> Wedd and of <i>Minthostachys andina</i> (Brett) Epling.

Abstract

ABSTRACT The essential oils of two plants (Hedeoma mandoniana and Minthostachys andina) of the mint family from the high valleys and mountains of Bolivia have been analyzed by a combination of GC/MS and retention indices. Both oils were found to contain pulegone as the major compound. The physical and chemical properties of the oils are similar to those of the well-known American and European pennyroyal oils.
