CUCA, LUIS E; BERNAL, FREDDY A; COY, CARLOS A  y  COY, ERICSSON D. ESSENTIAL OIL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF FRUITS OF Iryanthera ulei W. FROM COLOMBIA. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.4, pp. 363-365. ISSN 0717-9707.  doi: 10.4067/S0717-97072009000400008.

The essential oil was obtained by steam distillation from fruits of Iryanthera ulei Warb. growing in Colombia. The oil was analyzed by GC/FID and GC/ MS. The main components were a-muurolol (13.2%), spathulenol (12.1%), a-cadinol (7.8%), guaiol (4.0%), oplopanone (3.7%), 1,10-diepi-cubenol (3.4%) and limonene (3.3%) constituting a sesquiterpene-type enriched mixture. In addition, oil was tested for its antimicrobial activity against some Gram-positive and Gram-negative bacteria by means of a modified agar-well diffusion method. S. aureus strain was found to be the most sensitive microorganism.
