摘要

从灰杉（Stokes） F.A. Barkley)心材中分离得到23个化合物，包括4个黄酮醇（1-4）、2个黄酮（5-6）、1个黄酮酮(7)、2个二氢黄酮醇（8-9）、3个查尔酮（10-12）、2个黄烷-3,4-二醇（13-14）、7个单宁（15-21）和2个苯丙素（22-23）。通过光谱分析（包括NMR， MS和UV）并与先前报道的数据进行比较，实现了结构解析。除化合物1外，其余化合物（2 ~ 23）均为首次从该属植物中分离得到，其中17个化合物（2、4 ~ 13、15 ~ 19和23）为首次从该科植物中分离得到。并讨论了这些分离株的化学分类意义。

Phenolics from Toxicodendron vernicifluum (Stokes) F. A. Barkley (Anacardiaceae) and their chemotaxonomic significance

Phytochemical investigations on the heartwood of Toxicodendron vernicifluum (Stokes) F.A. Barkley resulted in the isolation of twenty-three compounds, including four flavonols (1-4), two flavones (5–6), one flavanone (7), two dihydroflavonols (8–9), three chalcones (10–12), two flavan-3,4-diols (13–14), seven tannins (15–21), and two phenylpropanoids (22–23). Structural elucidation was achieved through spectroscopic analysis (including NMR, MS, and UV) combined with comparison to previously reported data. Except for compound 1, all other compounds (2–23) were isolated from the genus Toxicodendron for the first time, and especially seventeen of them (2, 4–13, 15–19 and 23) were also isolated from the family Anacardiaceae for the first time. The chemotaxonomic significance of these 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.
