摘要
漆皮铁线莲地上部的植物化学研究。总共有26种成分，包括一种三萜，14种三萜皂苷，7种黄酮类化合物，3种苯丙素和一种香豆素。通过综合光谱分析和文献资料对比，鉴定了它们的结构。所有化合物均为首次从毛茛科植物中分离得到，山奈酚3-葡萄糖苷（19）、槲皮素-3- o -β-d-葡萄糖苷（1→3）-β-d-葡萄糖苷（20）、异牡荆素6″- o - e -咖啡酸（22）和3,4,5-三- o -咖啡酰奎宁酸（25）均为首次从毛茛科植物中分离得到。本文还讨论了这些化合物的化学分类意义。
Chemical constituents from the aerial parts of Clematis peterae
The phytochemical investigation of the aerial parts of Clematis peterae Hand-Mazz. led to a total of twenty-six constituents, including a triterpenoid, fourteen triterpenoid saponins, seven flavonoids, three phenylpropanoids and a coumarin. Their structures were identified by comprehensive spectroscopic analysis and comparison with literature data. All compounds were reported from C. peterae for the first time and kaempferol 3-glucuronide (19), quercetin-3-O-β-d-glucopyranosyl (1 → 3)-β-d-glucopyranoside (20), isovitexin 6″-O-E-caffeate (22) and 3,4,5-tri-O-caffeoylquinic acid (25) were firstly isolated from Ranunculaceae plants. This study also discussed the chemotaxonomic significance of these compounds.
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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
