摘要

月季的植物化学研究。鉴定出26种化合物，包括20种三萜（1-20）、4种苯丙衍生物（21-24）、1种二萜（25）和1种脂肪酸衍生物（26）。这些化合物的结构通过核磁共振（NMR）波谱法确认，并与文献资料交叉对照，以确保鉴定的可靠性。其中化合物3、5、6、11、15、18、22、25为首次在蔷薇属和蔷薇科中报道，具有独特的生化特性。此外，还对蔷薇科、菊科、茜草科等16个植物科的三萜进行了分布定位，探讨了它们的分类相关性。三萜以其结构多样性而闻名，可能作为研究进化或生态关系的潜在生物标志物。

Phytochemical investigation of Rosa laevigata leaves and their chemotaxonomic significance

A phytochemical study of Rosa laevigata Michx. leaves identified 26 compounds, including twenty triterpenoids (1–20), four phenylpropanoid derivatives (21–24), one diterpene (25) and one fatty acid derivative (26). The structures of these compounds were confirmed by using nuclear magnetic resonance (NMR) spectroscopy, and were cross-referenced with literature data, to ensure reliable identification. Compounds 3, 5, 6, 11, 15, 18, 22, 25 were reported within the genus Rosa and the family Rosaceae for the first time, suggesting unique biochemical traits. In addition, distribution mapping of triterpenoids across 16 plant families (e.g., Rosaceae, Asteraceae, Rubiaceae) was conducted to explore their taxonomic relevance. Triterpenoids, known for their structural diversity, may serve as potential biomarkers for investigating evolutionary or ecological relationships.

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.
