Abstract

A total of 18 compounds were isolated from whole Parasenecio auriculatus (DC.) H. Koyama plants, including eleven flavonoids (1–11), four mono-phenols (12–15), one triterpenoid (16), one coumarin (17), and one sterol (18). The chemical structures of these compounds were determined via nuclear magnetic resonance spectroscopy and mass spectrometry, then compared with published chemical structural data. All compounds were isolated from P. auriculatus for the first time, while compounds 4, 5, 7 and 10 were isolated from a species in the genus Parasenecio for the first time. The chemotaxonomic significance of these compounds is discussed.

auriculatus （DC.）的化学成分koyama及其化学分类意义

从整个auriculatus （Parasenecio auriculatus）中共分离到18个化合物。H. Koyama植物，包括11种类黄酮（1-11），4种单酚（12-15），1种三萜（16），1种香豆素（17）和1种甾醇（18）。这些化合物的化学结构通过核磁共振波谱和质谱测定，然后与已发表的化学结构数据进行比较。所有化合物均为首次从auriculatus中分离得到，其中化合物4、5、7和10为首次从Parasenecio属植物中分离得到。讨论了这些化合物的化学分类意义。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
