Cuatrec. and (Kunth) Cass.: Chemical and Enantioselective Analyses of Two Unprecedented Essential Oils from Ecuador.

This study presents the first chemical and enantioselective analyses of essential oils (EOs) derived from the leaves of two endemic species, Cuatrec. and (Kunth) Cass., from Loja, Ecuador.

A New Sesquiterpene Essential Oil from the Native Andean Species Less (Asteraceae): Chemical Analysis, Enantiomeric Evaluation, and Cholinergic Activity.

As part of a project devoted to the phytochemical study of Ecuadorian biodiversity, new essential oils are systematically distilled and analysed. In the present work, Less (Asteraceae) has been selected and some wild specimens collected to investigate the volatile fraction. The essential oil, obtained from fresh leaves, was analysed for the first time in the present study.
