Chemical composition and antimicrobial activity of the essential oil from croton heterocalyx baill. (Euphorbiaceae s.s.) leaves / Paulo Roberto H. Moreno in The journal of essential oil research, Vol. 21 N° 2+ supplément vol.20 (Mars/Avril 2009+ supplément 2008)

The oil which was analyzed by GC and GC/MS was found to contain germacrene D (12.5%), bicyclogermacrene (11.2%), δ-elemene (9.2%) β-elemene (8.2%), spathulenol (6.9%), linalool (5.4%) and 1,8-cineole (3.7%) as major components. Croton heterocalyx oil displayed a high inhibitory activity against the fungi Aspergillus niger (16404) and Candida albicans (ATCC 10231) as well as the Gram-positive bacterium Staphylococcus aureus (ATCC 6538), but a very weak activity was observed for the Gram-negative bacteria Escherichia coli (ATCC 8739) and Pseudomonas aeruginosa (ATCC 9027).

Twenty-seven compounds were identified representing 98.8% of the total oil. The oil from this species showed to be constituted by monoterpenes and sesquiterpenes in the same ratio. Among the monoterpenes, limonene (34.8%) and α-pinene (11.3%) were the main constituents, and β-bisabolene (10.7%) was the major substance for the sesquiterpene fraction.

Arg. leaves was investigated by GC, GC/MS and 13C-NMR spectroscopy. The oil was characterized by the presence of a high percentage of sesquiterpene hydrocarbons (45.6%) and aliphatic compounds (35.9%). The major constituents were β-caryophyllene (14.3%), bicyclogermacrene (14.2%) and nonadecanal (22.9%). Oxygenated sesquiterpenes (6.5%) and monoterpenes (6.4%) were also identified.
