Abstract

A phytochemical study of Acer tegmentosum Maxim (the dried stem bark of Acer tegmentosum Maxim) led to the isolation of 28 compounds, including thirteen phenols, five coumarins, four benzoate esters, three tetracyclic triterpenoids, one carbohydrate, one hydrocarbon and one lignan. The structures of these isolated compounds were identified using NMR spectroscopy (¹H and ¹³C) by comparison with previously reported data. To the best of our knowledge, salidroside, 2-(4-Hydroxyphenyl)ethyl β-d-galactopyranoside, 2-(4-hydroxyphenyl)ethyl 3,4,5-trihydroxybenzoate, 3,3´,4,4´-tetrahydroxybiphenyl, (4-methoxyphenyl)acetic acid, daphnetin, 5,6,7-trimethoxycoumarin, 1,2-bis(2-methylheptyl) 1,2-benzenedicarboxylate, 1,4-benzenedicarboxylic acid, periplocoside N and 3,4-dimethoxycinnamyl alcohol were reported from this plant for the first time. Chemotaxonomic significance was discussed.

Acer tegmentosum Maxim 的化学成分及其化学分类学意义

通过对 Acer tegmentosum Maxim（Acer tegmentosum Maxim 的干燥茎皮）进行植物化学研究，分离出 28 种化合物，包括 13 种酚类、5 种香豆素类、4 种苯甲酸酯类、3 种四环三萜类、1 种碳水化合物、1 种碳氢化合物和 1 种木脂素。利用核磁共振光谱（1H 和 13C）与以前报告的数据进行比较，确定了这些分离化合物的结构。据我们所知，水杨甙，2-（4-羟基苯基）乙基 β-d-吡喃半乳糖苷，2-（4-羟基苯基）乙基 3,4,5-三羟基苯甲酸酯，3,3´,4,4´-四羟基联苯，（4-甲氧基苯基）乙酸、首次从该植物中发现了水飞蓟素、5,6,7-三甲氧基香豆素、1,2-双（2-甲基庚基）1,2-苯二甲酸酯、1,4-苯二甲酸、紫苏甙 N 和 3,4-二甲氧基肉桂醇。讨论了化学分类学的意义。

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.
