Abstract
In this study, 24 compounds were isolated from the stem bark of Picea jezoensis var. komarovii (V.N. Vassil.) W.C.Cheng & L.K.Fu, comprising seven flavonoids (1–7), four phenolics (8, 10, 11, 17), one stilbene (9), two phenolic glycosides (12, 19), one coumarin (13), one organic acid (14), two lipids (15, 21), one aromatic glycoside (16), two acetophenone glycosides (18, 20), and three glycosides (22–24). The chemical structures of these metabolites were elucidated by NMR spectroscopy and compared with previously reported data in the literature. Compounds 1, 13–16, 23, and 24 were first isolated from a plant of the genus Picea, and 19, 20, and 22 were first isolated from a plant belonging to the Pinaceae family. The chemotaxonomic significance of these compounds is 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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
