COY BARRERA, C. A  and  GOMEZ, D. C. Characterization and Chemical Variability of Two Essential Oils From Croton funckianus (Euphorbiaceae). Ciencia en Desarrollo [online]. 2015, vol.6, n.2, pp.155-160. ISSN 0121-7488.

A chemical characterization from the essential oil obtained from leaves and fruits of two samples of Croton funckianus that were collected in two different sites (Fusagasugá and Bogotá) was conducted. The analysis was performed using gas chromatography coupled with mass spectrometry (GC-MS), and posteriorly, a comparison between the obtained profiles showed some differences for the leaves and a high percentage of similarity for the fruits. The analysis of the essential oil from the leaves of Croton funckianus collected in Fusagasugá showed as main components citronellal (22.8%), neral (18.6%), carvone (13.4%) and β-gurjunene (12.2%); whereas, for C. funckianus collected in were linalool (25.8%), α-terpineol (26.9%), limonene (18.9%) and neral (18.6%). In the fruit samples, differences in the major components percentages were observed, such that for the Fusagasuga sample were linalool (25.0%), borneol (15.5%) and neral (18.6%), and for the Bogotá sample were linalool (22%), borneol (13%) and neral (17.2%).
