摘要

通过对日本野百合（Mallotus japonicus Thunb.）茎进行植物化学研究，分离出 19 种代谢物（1-19）。通过核磁共振、ESIMS 和旋光数据分析，阐明了这些化合物的化学结构，发现了 18 种酚类化合物（1-18），包括一种香豆素（14）和四种木脂素（15-18），以及一种二萜（19）。值得注意的是，这些代谢物中有 11 种（7-11 和 13-18）以前在马缨丹属中未见报道。因此，对分离物的化学分类学意义进行了评估，结果表明 6′-O-vanilloylisotachioside (11) 和 daphnecin (14) 有可能作为区分日本野百合和其他植物物种的化学标记。

Chemical constituents of Mallotus japonicus Thunb. and their chemotaxonomic significance

A phytochemical investigation of the stems of Mallotus japonicus Thunb. led to the isolation of nineteen metabolites (1–19). The chemical structures of these compounds were elucidated, revealing eighteen phenolics (1–18), including one coumarin (14) and four lignans (15–18), and one diterpene (19) through analyses of NMR, ESIMS, and optical rotation data. Notably, eleven (7–11 and 13–18) of these metabolites were previously unreported within the genus Mallotus. Consequently, the chemotaxonomic significance of the isolates was evaluated, suggesting that 6′-O-vanilloylisotachioside (11) and daphnecin (14) hold the potential to serve as chemical markers for distinguishing M. japonicus from other plant species.

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.
