摘要

通过植物化学研究从 Elephantopus scaber L.中分离出八种化合物，其中包括六种木脂素（1-6）、两种黄酮类化合物（7-8）和两种三萜类化合物（9-10）。这些化合物的结构是通过全面的光谱方法鉴定的，并与现有的文献数据进行了比较。值得注意的是，根据分析，化合物 1-4、6 和 8 是在菊科中新发现的。此外，还讨论了这些分离化合物的化学分类。

Chemical constituents from Elephantopus scaber L. and their chemotaxonomic significant

The isolation of eight compounds from Elephantopus scaber L. through phytochemical studies yielded six lignans (1–6), two flavonoids (7–8), and two triterpenoids (9–10). The structures of these compounds were identified using thorough spectroscopic methods and compared with existing literature data. Notably, compounds 1–4, 6, and 8 were newly discovered in the Asteraceae family as per the analysis. Furthermore, the chemical classification of these isolated compounds was deliberated.

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
