摘要

采用液相色谱-四极轨道阱质谱法对石竹根和地上部位的三萜皂苷进行了综合分析，鉴定出了49种石膏皂苷元、松香酸和齐墩果酸苷元。通常，检测到的皂苷属葡萄糖醛酸齐墩烷型三萜羧酸3,28- bidesmosides (GOTCABs)，包括形成等压异构体的34种核心结构的多种乙酰化衍生物。首次鉴定出45种皂苷，主要存在于根中。支链三糖（HexA, pente, Hex/HexA, 2Hex）通过糖苷键连接在皂苷元的C-3上。C-28酯链主要由单糖、二糖和三乙酰四糖和五糖组成。讨论了GOTCAB皂苷在该物种中的化学化学意义。

Oleanane-type bidesmosides from Agrostemma githago L. roots and aerial parts

A comprehensive analysis of triterpenoid saponins in Agrostemma githago L. (Caryophyllaceae) by liquid chromatography – quadrupol-Orbitrap mass spectrometry allowed for annotation of 49 gypsogenin-, quillaic acid- and oleanolic acid-bidesmosides in the roots and aerial parts. Generally, the detected saponins belong to Glucuronide Oleanane-type Triterpenoid Carboxylic Acids 3,28-Bidesmosides (GOTCABs) including a variety of acetylated derivatives of 34 core structures forming isobaric isomers. For the first time, forty five saponins were annotated in the A. githago, being present particularly in the roots. The branched trisaccharide (HexA, Pent, Hex/HexA, 2Hex) is linked at C-3 of the sapogenin via glycosidic bond. C-28 ester chain consists mainly of mono-, di- and triacetyl tetra- and pentasaccharides. The chemophenetic significance of GOTCAB saponins in this species 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.
