URZUA, ALEJANDRO; SANTANDER, ROCÍO y ECHEVERRIA, JAVIER. ANALYSIS OF SURFACE AND VOLATILE COMPOUNDS OF FLOWER HEADS OF FLOURENSIA THURIFERA (MOL) D.C.. J. Chil. Chem. Soc. [online]. 2007, vol.52, n.3, pp. 1244-1245. ISSN 0717-9707. http://dx.doi.org/10.4067/S0717-97072007000300011.
Surface compounds were obtained by a methylene chloride extraction of fresh flower heads of Flourensia thurifera. The methylene chloride extract was purified by column chromatography and analyzed by GC-MS, leading to the identification of several monoterpenes, sesquiterpenes and diterpenes. A hydrocarbon fraction of n-alkanes from C23 to C31 and C33 was also identified. Headspace analysis of the fresh flower heads was also carried out. Different proportions of the same mono- and some of the sesquiterpenes were identified in the volatile fraction. The presence of mono- and sesquiterpenes in the flower heads is in agreement with the fact that these families of compounds have been identified in other Flourensiaspecies
