摘要

大玉兰叶的植物化学研究。得到18个化合物，包括6个四萜（1-6）、6个生物碱（7-12）、4个苯丙素（13-16）和2个苯甲醛衍生物（17-18）。它们的结构是通过全面的核磁共振分析以及与文献的光谱数据比较来实现的。其中，2个和3个为首次从植物源分离鉴定的天然产物，11个和12个为首次从木兰科中分离报道，4-6个和15个为首次从木兰属中分离得到。本研究有助于了解桔梗属植物的化学多样性，并对这些分离化合物的化学分类意义进行了探讨。

Chemical constituents from Magnolia grandiflora Linn leaves and their chemotaxonomic significance

A phytochemical investigation of the leaves of Magnolia grandiflora Linn. afforded eighteen compounds, including six sequiterpenes (1–6), six alkaloids (7–12), four phenylpropanoids (13–16), and two benzaldehyde derivatives (17–18). Their structural elucidation was achieved by comprehensive NMR analysis as well as by comparison of their spectroscopic date with the literature. Among them, 2 and 3 are firstly isolated and identified as nature products from plant source, 11 and 12 are being firstly reported from the family Magnoliaceae, and 4–6 and 15 were obtained from the genus Magnolia for the first time. This work contributes to the understanding of the chemical diversity of M. grandiflora and also the chemotaxonomic significance of these isolated 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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
