Abstract

The phytochemical studies on the bark of Cyathostemma wrayi King resulted in the identification of ten alkaloids consisting of four oxoaporphines; lysicamine (1), atherospermidine (2), thalicminine (3), liriodenine (4), five aporphines; xylopine (5), nornuciferine (6), annonaine (7), norstephalagine (8), asimilobine (9), and one propaporphine; stepharine (10). The structural characterisation of all the isolated alkaloids was confirmed through the analysis of spectroscopic data and comparison with literature data. This is the first report on the alkaloids of Cyathostemma wrayi and also the first report on the occurrence of aporphine (1–3) and proaporphine (5–10) alkaloids in the genus of Cyathostemma. In addition, the chemophenetic significance of the isolated alkaloids was summarized.

Cyathostemma wrayi king 的化学成分及其化学遗传学意义

对 Cyathostemma wrayi King 树皮进行的植物化学研究发现了 10 种生物碱，包括 4 种氧化卟吩；(1)、therospermidine (2)、thalicminine (3)、liriodenine (4)，五种porphines；xylopine (5)、nornuciferine (6)、annonaine (7)、norstephalagine (8)、asimilobine (9)，以及一种 propaporphine；stepharine (10)。通过光谱数据分析以及与文献数据的比较，确认了所有分离生物碱的结构特征。这是第一份关于 Cyathostemma wrayi 生物碱的报告，也是第一份关于 Cyathostemma 属中出现 aporphine（1-3）和 proaporphine（5-10）生物碱的报告。此外，还总结了分离出的生物碱的化学遗传学意义。

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.
