Abstract

A phytochemical study on the seeds of Peganum harmala led to the separation of 22 alkaloids, including quinazoline alkaloids (1–10), β-carboline alkaloids (11–18), and others alkaloids (19–22). Their structures were identified by comprehensive spectroscopic analysis and comparison with literature data. Compounds 14 and 20–22 were first isolated from Zygophyllaceae family. Compounds 8 and 15 were firstly discovered as natural products. Moreover, the chemotaxonomic significance of the isolated alkaloids is discussed.

鹅掌楸种子中的生物碱及其化学分类学意义

通过对 Peganum harmala 种子进行植物化学研究，分离出 22 种生物碱，包括喹唑啉类生物碱（1-10）、β-咔啉类生物碱（11-18）和其他生物碱（19-22）。通过全面的光谱分析和与文献数据的比较，确定了它们的结构。化合物 14 和 20-22 首次从茜草科植物中分离出来。化合物 8 和 15 是首次发现的天然产物。此外，还讨论了所分离生物碱的化学分类学意义。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
