Abstract
Environmental factors have an influence on the chemistry and percentage recovery of volatile oils. Therefore, the chemical composition of Eucalyptus globulus (E. globulus) volatile oil from Botswana was determined. The volatile oil was isolated from the leaves of E. globulus plant by means of the conventional hydrodistillation and ultrasound assisted hydrodistillation at 50 W and 300 W. The extraction method that gave a better recovery of the volatile oil was ultrasound assisted hydrodistillation at 300 W with a yield of 2.50%. The volatile oil obtained by hydrodistillation and ultrasound assisted hydrodistillation at 50 W had comparable recovery yields of 2.24% and 2.20% respectively. Eucalyptol was identified as the major component in the oil. The amount of eucalyptol present in E. globulus volatile oil extracted by ultrasound assisted hydrodistillation (65%) show that the oil has a potential to be explored for therapeutic purposes.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
