摘要

从水蚤茎中分离出16种已知化合物（1-16）。包括6种酚类化合物（1-6），1种甾醇(7)，1种三萜(8)和8种木脂素（9-16）。其中15个化合物（1 ~ 6,8 ~ 16）为首次从水蚤科中分离得到。分离得到的化合物对枯草芽孢杆菌、金黄色葡萄球菌和大肠杆菌等三种细菌进行了体外抗菌活性测试。化合物15对这些细菌具有明显的抑菌活性。详细讨论了该植物分离化合物的化学分类意义。

Chemical constituents from the stems of Daphniphyllum angustifolium Hutch. and their chemotaxonomic significance

The phytochemical investigation of the stems of Daphniphyllum angustifolium resulted in the isolation of sixteen known compounds (1–16). This collection included six phenolic compounds (1–6), one sterol (7), one triterpene (8), and eight lignans (9–16). Among them, fifteen compounds (1–6, 8–16) were identified for the first time within the Daphniphyllaceae family. The isolated compounds underwent in vitro testing for antibacterial activity against three bacterial strains, including Bacillus subtilis, Staphylococcus aureus, and Escherichia coli. Compound 15 exhibited significant antimicrobial activity against these bacteria. The chemotaxonomic significance of the isolated compounds from the D.angustifolium is discussed in detail.

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
