SALDARRIAGA C, Luis F et al. Agroindustrial evaluation of essential oils of Artemisia dracunculos L, Franseria artemisioides Willd, Salvia officinalis L, Lippia dulcis Frev, and Occimun americanum L in conditions of the Cauca Valle. Acta Agron. [online]. 2010, vol.59, n.3, pp.293-302. ISSN 0120-2812.

From plots established of the medicinal plants work collection at the Experimental Center CEUNP at Cauca Valle conditions, the vegetable material was gathered by manual cutting in 0.25m²; they separated leaves, shafts and flowers of each species, the percentage of dry matter was determined and it was conditioned for the process of extraction of oil essential, which was carried out by means of haulage with vapour. To the obtained oils they were measured the density, the refraction index and to that of more yield in each species was analyzed by gas chromatograph coupled to mass spectrometry. The biggest yields of oil essential were presented in the leaves in all the species; were the most representative chemical compounds the Elemicina (40.11%) in Tarragon, b-Himachaleno (53.98%) in Marco, trans -b- Cariofileno (22.18) in Kitchen sage, a- Bisabolol (15.79%) in Aztec sweet herb and 1,8- Cineol (Eucaliptol) (23.34%) in Lime basil. The physical properties were appropriate with the presence of the opposing chemical compounds. All the essential oils presented uses agroindustrial potentials, varying these according to the species and to their components, from uses in the sector of fragrances, cosmetic, medicinal, nutritious, as well as in the agricultural sector.
