Abstract
Venezuela is a country with high biodiversity. The specie Morella parvifolia belongs to the Myricaceae family, which is rich in essential oils. The study of M. pubescens essential oil is the only reported in this genus. Its major component is germacrene - B (~ 32%). The present work reports the chemical composition of the essential oil of Morella parvifolia (Benth.) Parra -O. collected in Venezuela. The essential oil (0.3 - 0.5 % yield) of the fresh leaves of M. parvifolia from three different plants, from the same location, were obtained by hydrodistillation using a Clevenger type apparatus. The chemical constituents were identified by GC-MS analysis. From twenty three to twenty nine compounds (96.06 – 97.31 % of the samples) were identified. The major constituents found were α - bisabolol (50.56 - 58.9 %) and α - pinene (12.88 - 16.79%). Analysis of antimicrobial activity on Gram (+) and Gram (-) strains was performed but no antibacterial activity was observed. .
Highlights
Venezuela is among the ten biodiversity-rich countries in the world (UNEP-WCMC, 2010)
This paper aims to identify the chemical components of essential oil of Venezuela Morella parvifolia and determine its antibacterial activity against Gram (+) and Gram (-) bacteria
Hydrodestilation of M. parvifolia leaves produced slightly yellow oil which yielded from 0.3 - 0.5 %
Summary
Venezuela is among the ten biodiversity-rich countries in the world (UNEP-WCMC, 2010). A huge part of this biodiversity still needs to be studied. In the tropical Andes, the paramo is located, usually on the line just above where the cloud forest ends and below the snow line. The paramo is the most biodiverse high mountain ecosystem in the world. Morella parvifolia (Benth.) Parra-O. belongs to Myricaceae (Hokche, 2008) family. It is a shrub of almost 4m high with leaves and fragrant fruits that grows wild in the Venezuelan Paramo (Parra, 2002).
