Abstract

Phytochemical investigation of Gentiana davidi led to isolation of a total of 21 compounds, including seven benzoic acid derivatives (1–7), one alkaloid compound (8), seven iridoids (9–15), and six flavonoids (16–21). The chemical structures of these compounds were characterized by spectroscopic analysis, and their NMR data were compared with those reported in the literature. Among them, compound 1 was identified as a new benzoic acid derivative, and compounds 2–21 are identified and reported for the first time from this plant. The chemotaxonomic significance of these isolated compounds from the G. davidi is discussed.

龙胆草中一种新的苯甲酸衍生物及其化学分类学意义

通过对 Gentiana davidi 的植物化学研究，共分离出 21 种化合物，其中包括 7 种苯甲酸衍生物（1-7）、1 种生物碱化合物（8）、7 种虹膜类化合物（9-15）和 6 种黄酮类化合物（16-21）。通过光谱分析确定了这些化合物的化学结构，并将其核磁共振数据与文献报道的数据进行了比较。其中，化合物 1 被鉴定为一种新的苯甲酸衍生物，化合物 2-21 是首次从该植物中鉴定和报道的。本文讨论了从 G. davidi 分离出的这些化合物的化学分类学意义。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
