Abstract
The genus Lippia L., included within the Verbenaceae family, has a wide geographical distribution in Tropical and Subtropical South Africa and America. Lippia javanica (Burm.f.) Spreng is a woody, multi-stemmed shrubbery native to central, eastern and southern Africa. In this work the chemical composition of the aerial part of essential oil of a Kenyan accession of L. javanica, harvested in the Masai Mara National Reserve, never previously studied, was evaluated by GC-MS. Essential oil (Lj) was characterised by good amounts of esters (58.1%) with octyl acetate (33.7%), the main constituent of the oil, octyl butanoate (19.1%) and hexyl butanoate (4.6%) as principal metabolites. Monoterpene hydrocarbons (33.5%) were mainly represented by β-myrcene (30.6%). An update of the chemical composition of all the essential oils (EOs) of Lippia javanica, studied to date, clearly indicates that the accession subject of the present work can be considered a new chemotype.
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.
