Aromatic Des-A-triterpenoid Hydrocarbons in Jurassic Coals from the Turpan-Hami Basin

    摘要
  • 摘要: 利用ＧＣ－ＭＳ技术，在吐哈盆地中侏罗统褐煤中下检出了一类脱Ａ环芳香三萜类烃化合物，碳数范围为Ｃ20－Ｃ24；通常以ｍ／ｚ（Ｍ+－１５）峰为基峰，Ｄ．Ｅ环开裂及重排类碎片峰具有较高丰度；根据质谱解析，裂解机理分析及对比研究，确定其具有宏的基本骨架结构，但甲基取代数量及位置各异，通常Ｂ环为芳环，Ｃ、Ｄ环各含一个双键，Ｃ－１４位含有甲基。该类化合物的形成与母质和沉积环境有关，浅水淡水氧化性泥炭沼泽，有利于细菌等微生物的繁殖及其对类脂组分的改造与富集，高等植物三萜烯类母质易于通过光化学反应及／或微生物参与的脱Ａ环和芳构化作用而形成此类化合物，此类化合物首次检出于中生代沉积有机质，表明其并非仅来源于第三纪以来的被子植物，裸子植物如针叶类也可能是重要母源之一。
    Abstract: A series of aromatic des-A-triterpenoid hydrocarbons were identified in some Jurassic coals from the Turpan-Hami Basin. Their carbon numbers are of CＣ20 to Ｃ24, with molecular weights of 264￣320. These compounds are characterred by m+ -15 base peaks and same mass spectral fragments such as m/z 193, 195, 207,209, 178, 179, 181, 165, 155, 189, 191, 205, 102, 119, 55, 69, 83, 109 and 111. Based on mass spectral characteristics, cleavage mechanism analysis and comparison to the published mass spectra, these compounds are confirmed to be of structural skeleton of chrysenes ; with different amounts and positions of methyl groups;and with B- ring aromatized but C and D-ring containing one double-bond respectively.M+-15 base peaks are suggested to be caused by loss of C-14 methyl. These compounds are suggested to be derived mainly from highter plant 3-oxygenated pentacyclic triterpenoids (oleanane and ursane series)by photochemically and/or microbially mediated loss of ring A and subsequent aromatisations. Their identifications in the Jurassic coals may suggest that these compounds are derived not only from angiosperms but also from gymnosperms.
