Abstract

ABSTRACT The genera Nigella and Garidella are two members of the Nigelleae tribe. Among all the taxa of the tribe, black cumin (Nigella sativa L.) is one of the most important plants concerning economic and medicinal uses. In this study, volatiles were analyzed in detail to elucidate the phytochemical profiles and to understand the taxonomic patterns of secondary metabolites for 19 taxa of Nigella and Garidella collected from Turkey and the neighboring countries. Volatiles were analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC/MS) using different polarity columns. Seventeen Nigella and two Garidella taxa were investigated, with 130 volatile oil components characterized. Structural similarities of the compounds were clustered by a machine learning algorithm using the molecular fingerprinting method. Our results depict that the phytochemicals produced by Nigelleae can be classified independently of their chemical families and significantly contribute to genera delimitation by their structural distances.

植物化学成分的结构相似性对毛茛科黑草属和毛茛属植物的物种划分有重要意义。

Nigella属和Garidella属是Nigelleae部落的两个成员。在部落的所有分类群中，黑孜然(Nigella sativa L.)是最重要的经济和药用植物之一。本研究对土耳其及周边地区19个Nigella和Garidella分类群的挥发物进行了详细的分析，以阐明其植物化学特征和次生代谢产物的分类模式。采用气相色谱法(GC- fid)和气相色谱-质谱法(GC/MS)分析挥发物。研究了17种黑草属和2种黑草属植物，鉴定了130种挥发油成分。利用分子指纹技术的机器学习算法对化合物的结构相似性进行聚类。研究结果表明，尼格莱属植物化学物质可以独立于其化学科进行分类，并通过其结构距离对属划分有重要贡献。

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.
