Chemical composition of essential oil leaves Hedyosmum translucidum Cuatrec., Chloranthaceae (Granizo)

Abstract

Essential oil composition of granizoʼs leaves, Hedyosmum translucidum Cuatrec., Chlorantaceae, certified identification Herbarium PSO, collected in town Santa Barbara, Pasto, Colombia were analyzed in this work. This genus is reported with an index value of eco systemic importance. The essential oil was obtained by means of microwave radiation-assisted hydro distillation, extraction yield was 1.2%. The components in the essential oil were identified by gas chromatography-mass spectrometry (GC-MS). The most abundant components were: α-eudesmol (11.4%), germacrene D (8.9%), trans-β-caryophyllene (7.8%), elemol (5.8%) and caryophyllene oxide (5.3%). These compounds are classified as sesquiterpenes. The observed relative amounts of the most abundant constituents of H. translucidum, were different to those reported for other species of genus Hedyosmum in Bolivia, Venezuela and Brazil. This paper is a starting knowledge to be defined as a promising species.
