摘要

摘要:本研究的目的是对木参的化学和化学计量学进行分析。Heuff交货。精油在不同发展阶段，重点是化学分类学。在各物候阶段，除营养期以单萜烃为主(51.1%)外，油中含氧单萜烯含量最高(21.3 ~ 61.2%)。香叶醇、柠檬烯、对花香烃和冰片是不同发育阶段香精油中含量最多的化合物。在植株发育过程中，香叶醇含量变化最大，变异系数为112.3%。化学计量学分析显示两种化学型:柠檬烯/对伞花素/香叶醇和柠檬烯/对伞花素/冰片。我们认为三种最丰富的EO成分应该决定化学型。我们的结果得出结论，从该植物中分离1个月的精油不应该用于确定化学型。

Seasonal variation in the essential oil of Satureja kitaibelii determines chemotypes

ABSTRACT The aim of the present study was a chemical and chemometric analysis of Satureja kitaibelii Wierzb. ex Heuff. essential oil during different stages of development, with emphasis on chemotaxonomy. The most abundant compound class in the S. kitaibelii oil during examined phenological stages was oxygenated monoterpenes (21.3–61.2%), except vegetative stage, in which monoterpene hydrocarbons are dominant (51.1%). Geraniol, limonene, p-cymene and borneol are the most abundant compounds of essential oil during different stages of development. The highest variation in content, during plant development, was shown by the most dominant component, geraniol (coefficient of variation 112.3%). Chemometric analysis indicated two chemotypes: limonene/p-cymene/geraniol and limonene/p-cymene/borneol. We are of the opinion that the three most abundant EO components should determine the chemotype. Our results lead to the conclusion that essential oil isolated from the plant in 1 month should not be used to determine the chemotype.

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
