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 leaf essential oil from the Andean species Gynoxys szyszylowiczii Hieron. of southern Ecuador: chemical and enantioselective analyses.

The essential oil obtained from the dry leaves of Gynoxys szyszylowiczii Hieron. was described in this study for the first time. The chemical analysis, conducted on two stationary phases of different polarity, permitted to identify sixty-four compounds, that were quantified with at least one column.

New Essential Oils from Ecuadorian Cuatrec. and Cuatrec. Chemical Compositions and Enantioselective Analyses.

The present study belonged to an unfunded project, dealing on the systematic description of unprecedented essential oils (EOs), distilled from 12 species of genus Cuatrec. In this very case, the aim was the first chemical and enantiomeric analyses of two volatile fractions, obtained from the leaves of Cuatrec. and Cuatrec.

Chemical and Enantioselective Analyses of an Unprecedented Essential Oil from Ecuadorian : A Natural Source of S-Methyl-O-2-phenylethyl Carbonothioate.

Fresh and dry leaves of (Sw.) R. Rohde (Lauraceae) produced, in a quite high yield (0.

A new essential oil from the native Ecuadorian species Steiractinia sodiroi (Hieron.) S.F. Blake (Asteraceae): chemical and enantioselective analyses.

In the present study, the essential oil from dry leaves of Steiractinia sodiroi (Hieron.) S.F.

A New Essential Oil from the Native Andean Species Klotzsch ex Nees of Southern Ecuador: Chemical and Enantioselective Analyses.

The leaves of Klotzsch ex Nees, belonging to the family, Lauraceae, were collected in the province of Loja (Ecuador), dried, and analytically steam-distilled. An unprecedented essential oil was obtained, with a 0.03% yield by weight of dry plant material.

Microwave-Assisted Extraction Optimization and Effect of Drying Temperature on Catechins, Procyanidins and Theobromine in Cocoa Beans.

Cocoa beans ( L.) are an important source of polyphenols. Nevertheless, the content of these compounds is influenced by post-harvest processes.

A New Essential Oil from the Leaves of Muschl. (Asteraceae) Growing in Southern Ecuador: Chemical and Enantioselective Analyses.

An essential oil, distilled from the leaves of the Andean species Muschl., is described in the present study for the first time. The chemical composition was qualitatively and quantitatively determined by GC-MS and GC-FID, respectively.
