Chemical constituents from Alnus mandshurica and their chemotaxonomic significance

A phytochemical study of Alnus mandshurica (Callier) Hand.-Mazz. (dried stem bark) led to the isolation of 28 compounds, including twelve simple phenols and simple phenol glycosides (1–12), eleven flavonoids (13–23), among them, compounds 13, 15, 17, 18, and 23 are flavan-3-ols compounds, two coumarins (24 and 25), one diarylheptanoid (26), one lupine triterpenoid (27), one sterol (28). The structures of these isolated compounds were identified using NMR spectroscopy (¹H and ¹³C) by comparison with previously reported data. Compounds 2, 5–14, 18, 20, 22, 25–27 were isolated from A. mandshurica for the first time. The chemotaxonomic significance of the isolates was also discussed.

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
