Abstract

The investigation of the phytochemistry on the aerial parts of Rosa omeiensis f. pteracantha result in the isolation and authentication of one new phenolic compound, named methyl gallate 3-O-β-D-(6′-O-(p-hydroxybenzoyl))-glucopyranoside (1), along with nine known ones (2–10), and one prenylated benzoic acid derivative (11). The structure of the new compound was unambiguously characterized by comprehensive analysis of IR, UV, HR-ESI-MS, 1D NMR, and 2D NMR spectra, as well as comparative literature on optical rotation. Other compounds were identified as known structures by referencing their NMR data with literatures. All the isolated compounds were reported for the first time from R. omeiensis f. pteracantha. The chemotaxonomic significances of isolated compounds were discussed accordingly.

翼棘蔷薇酚类化合物及其化学分类意义

对翼棘Rosa meeiensis f. pteracantha地上部分的植物化学研究，分离并鉴定了一种新的酚类化合物，命名为没食子酸甲酯3-O-β- d -（6 ' - o -（对羟基苯甲酰））-葡萄糖吡喃苷(1)，以及9种已知化合物（2-10），以及一种戊基苯甲酸衍生物（11）。通过IR、UV、HR-ESI-MS、1D NMR和2D NMR光谱的综合分析以及旋光性比较文献对新化合物的结构进行了明确的表征。其他化合物通过参考文献的核磁共振数据被鉴定为已知结构。所有化合物均为首次从该植物中分离得到。并对分离化合物的化学分类意义进行了讨论。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
