摘要

金银花花蕾的植物化学研究。分离得到23个五环三萜皂苷，包括3个羽扇豆素型（1-3）、13个hederin型（4-16）、6个齐墩烷型（17-22）和1个石膏酸型（23）。通过广泛的光谱方法和文献资料的比较，鉴定了这些皂苷的结构。其中化合物1 ~ 9、11 ~ 21和23为首次从该属植物中分离得到，化合物12、15 ~ 16和20 ~ 21为新从该属植物中分离得到。化合物1 ~ 3、5 ~ 8、11、14、19和23均为首次从辣椒科植物中分离得到。并对这些分离得到的五环三萜皂苷的化学分类意义进行了描述。

Pentacyclic triterpenoid saponins from the flower buds of Lonicera macranthoides Hand.-Mazz. and their chemotaxonomic significance

A phytochemical investigation of the flower buds of Lonicera macranthoides Hand.-Mazz. led to the isolation of twenty-three pentacyclic triterpenoid saponins, including three lupine-type (1–3), thirteen hederin-type (4–16), six oleanane-type (17–22) and one gypsogenic acid-type (23). The structures of these saponins were identified based on extensive spectroscopic methods as well as comparison with literature data. To the best of our knowledge, compounds 1–9, 11–21 and 23 were isolated from L. macranthoides for the first time, compounds 12, 15–16 and 20–21 were newly identified within the genus Lonicera. Compounds 1–3, 5–8, 11, 14, 19 and 23 were firstly acquired from the family Caprifoliaceae. The chemotaxonomic significance of these isolated pentacyclic triterpenoid saponins was also described.

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.
