Abstract

A phytochemical investigation of flower buds of Wikstroemia Chamaedaphne Meissn. resulted in the isolation of 21 terpenoids (1–21), three lignans (22–24) and one aromatic compound (25). These compounds were elucidated using spectroscopic methods and comparing their data to those reported in the literature. Compounds 14, 18 and 22 were first isolated from the family Thymelaeaceae. Compounds 17, 19–21 and 25 were initially obtained from the genus Wikstroemia, while terpenoids 5, 15 and 16 have not been previously isolated from this species. In addition, distribution mapping of terpenoids was performed to explore their possible chemotaxonomic values among species of the family Thymelaeaceae, Euphorbiaceae, Lamiaceae, Rosaceae and Asteraceae.

野蔷薇花蕾的化学成分。（百里香科）及其化学分类意义

紫丁香花蕾的植物化学研究。分离得到21个萜类化合物（1-21）、3个木脂素（22-24）和1个芳香化合物（25）。这些化合物用光谱方法进行了鉴定，并与文献报道的数据进行了比较。化合物14、18和22为首次从百里香科植物中分离得到。化合物17,19 - 21和25最初从Wikstroemia属中分离得到，而萜类化合物5,15和16先前未从该物种中分离得到。此外，我们还绘制了萜类化合物在百里香科（Thymelaeaceae）、大戟科（Euphorbiaceae）、灯叶科（Lamiaceae）、蔷薇科（Rosaceae）和菊科（Asteraceae）的分布图谱，探讨了它们可能的化学分类价值。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
