摘要

对水仙桃科（Anacardiaceae）果实75%乙醇提取物进行化学研究，通过核磁共振（NMR）波谱及与文献资料比较，分离鉴定了20个化合物。其中包括8种黄酮类化合物（1-8），2种酚类衍生物（9-10），5种苯丙类衍生物（11-15），3种倍半萜（16-18）和2种木脂素（19-20）。其中化合物3、9、14、15、17和20为首次从毒刺属植物中分离得到，化合物1、7、10、12、13、16、18和19为首次从毒刺科植物中分离得到。根据以往的植物化学研究，推测双黄酮是其果实中含量较高的成分。本文还讨论了这些分离株的化学分类意义。

Chemical constituents from the fruits of Toxicodendron vernicifluum (Stokes) F. A. Barkley (Anacardiaceae) and their chemotaxonomic significance

In the chemical investigation on the 75 % ethanol extract of the fruits of Toxicodendron vernicifluum (Stokes) F.A. Barkley (Anacardiaceae), a total of twenty compounds were isolated and identified by means of nuclear magnetic resonance (NMR) spectroscopy and comparison with literature data reported previously. These include eight flavonoids (1–8), two phenolic derivatives (9–10), five phenylpropanoid derivatives (11–15), three sesquiterpenes (16–18), and two lignans (19–20). Notably, compounds 3, 9, 14, 15, 17 and 20 were isolated from the genus Toxicodendron for the first time, whereas compounds 1, 7, 10, 12, 13, 16, 18, and 19 were isolated from the family Anacardiaceae for the first time. Based on previous phytochemical studies on T. vernicifluum, biflavonoids are presumably the constituents with relatively high content in its fruits. The chemotaxonomic significance of these isolates is 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.
