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.

爪哇Lippia javanica （Burm.f.）一个新的化学型采集于马赛马拉国家保护区（肯尼亚）的春：其空中部分的精油化学成分。

马鞭草属（Lippia L.）属于马鞭草科，在热带和亚热带的南非和美洲有广泛的地理分布。爪哇利皮亚（缅甸）春是一种木质多茎灌木，原产于非洲中部、东部和南部。在这项工作中，用气相色谱-质谱法评估了在马赛马拉国家保护区收获的一种肯尼亚javanica的精油的空中部分的化学成分，以前从未研究过。精油（Lj）的主要代谢产物是大量的酯（58.1%）和乙酸辛酯（33.7%），其中丁酸辛酯（19.1%）和丁酸己酯（4.6%）为主要代谢产物。单萜烃（33.5%）以β-月桂烯（30.6%）为主。迄今为止所研究的爪哇Lippia javanica所有精油（EOs）的化学成分更新清楚地表明，本工作的加入主题可以被认为是一种新的化学型。

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.
