摘要
DelphiniumL.(兰科）是一个分类复杂的属，由大约 365 种多年生草本植物组成。化学分类法对于协助和补充该属的分类非常重要。本研究对中国特有的 Delphinium tatsienense Franch.进行了植物化学研究，发现了两种以前未曾描述过的蒽酰胺衍生物 tatsieamides A 和 B (1-2)。分离出的蒽酰胺类化合物具有化学分类学价值，可用作良好的化学标记，为 D. tatsienense 及相关物种的化学分类学提供有价值的信息。
Two new anthranilamides with chemotaxonomic value from Delphinium tatsienense
Delphinium
L. (Ranunculaceae) is a taxonomically complex genus composed of approximately 365 species of perennial herbs. Chemical taxonomy is highly important for assisting and supplementing the taxonomy of this genus. In the present study, Delphinium tatsienense Franch., a Chinese endemic Delphinium species, was phytochemically investigated, which led to the discovery of two previously undescribed anthranilamide derivatives, tatsieamides A and B (1–2). The isolated anthranilamides possess chemotaxonomic value and could be utilized as good chemical markers to provide valuable information for the chemotaxonomy of D. tatsienense and related species.
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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
