DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

We investigated morphological and DNA sequence data for studying the composition and phylogenetic relationships of the Lecointea clade sensu Herendeen and for testing its monophyly. Twenty nine representing 14 genera were analyzed, including all members of the Lecointea clade and some species of the genera Acosmium, Luetzelburgia, Sweetia, Vatairea and Vataireopsis. Ateleia herbert-smithii, Bocoa mollis, and Myrocarpus frondosus were included as outgroup. Matrices were analyzed using maximum parsimony. Analyses of morphological data, chloroplast DNA trnL sequence data, and combined datasets resulted in similar tree topologies. The Lecointea clade sensu Herendeen, with the additional inclusion of Uribea, is monophyletic in all analyses. Exostyles and Harleyodendron belong to the Lecointea clade and not to the Vatairea clade as recently proposed by Pennington & al.

(-)-1-Methyl-4-acetyl-1-cyclohexene (I) was found in essential oil of Myrocarpus frondosus and Myrocarpus fastigiatus and its enantiomer were synthesized from (+)-limonene as reported in the literature.  The authors have obtained I from isoprene and menthyl acrylate by partial asym. synthesis.
