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： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
