Abstract

Magnolia lamdongensis (Magnoliaceae), an endemic species of Vietnam, was selected for our study on its chemical composition. By various chromatographic techniques, sixteen compounds were isolated for the first time from the methanol extract of M. lamdongensis leaves, including five flavonoids (1–5), six lignans (6–11), a phenylpropanoid (12), a phenolic glycoside (13), a phenylethanoid glycoside (14), and two cerebrosides (15–16). The structures of the compounds were elucidated using NMR, MS, and CD spectra. Flavonoids, lignans, phenylpropanoids, phenolic glycosides, and phenylethanoid glycosides have been widely reported from Magnolia; however, the cerebrosides have not been discussed in this genus in the previous literature.

白玉兰叶片次生代谢产物及其化学分类意义

选取越南特有植物木兰（Magnolia lamdongensis，木兰科）进行化学成分研究。采用多种色谱技术，首次从兰登叶甲醇提取物中分离到16个化合物，包括5个黄酮类化合物（1-5）、6个木脂素（6-11）、1个苯丙素（12）、1个酚类苷（13）、1个苯乙醇苷（14）和2个脑苷（15-16）。化合物的结构通过核磁共振、质谱和CD谱进行了鉴定。白玉兰中黄酮类、木脂素类、苯丙素类、酚类苷类和苯乙醇类苷类已被广泛报道；然而，在以前的文献中尚未讨论过该属的脑苷类。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
