(1) Since an Offline-TMAH (tetramethylammonium hydoxide)-GCMS method was more suitable than online-TMAH-GCMS for analysis of lignin in plants and sediments, the reaction conditions were examined. As a result, the reaction condition is the most suitable at 300℃ for 30 minutes.(2) Pollens, leaves, braches and resins of about 100 species of conifers, broad leaf trees and herbaceous plants were collected, and organic matter analysis by the TMAH-GCMS method was conducted. The difference and features between the compositions of fatty acids, lignin phenols and cutin acids in each parts of plants vegetable part, lignin and cutin acids have become clear.(3) Changes of vegetations were examined by the organic matter analyses in the Lake Baikal sediment and peripheral wetland soils. As a result, it has turned out that the results of the pollen-analyses and the multivariate-analyses of organic matter compositions of lignin phenols, fatty acids and cutin acids correspond in the divisions into periods of vegetation.(4) The data base was constructed that mass spectra of each compound is linked with organic matter compositions of pollens, leaves, braches and resins. The data base from systematic analyses of plants has a significant meaning for organic geochemistry.

(1)由于离线-TMAH(氢氧化四甲基铵)-GCMS方法比在线-TMAH-GCMS方法更适合植物和沉积物中的木质素分析，因此对反应条件进行了检查，结果发现该反应条件是最合适的。 (2)采集约100种针叶树、阔叶树和草本植物的花粉、叶片、枝条和树脂，有机采用TMAH-GCMS方法进行物质分析，明确了植物各部位脂肪酸、木质素酚和角质酸的组成差异和特征。(3)植被变化。通过对贝加尔湖沉积物和周边湿地土壤中的有机质分析进行了检查，结果表明，花粉分析和有机质成分的多元分析结果是一致的。木质素酚、脂肪酸和角质酸的含量与植被的时期划分相对应。(4)通过系统分析将各化合物的质谱与花粉、叶片、枝条和树脂的有机质成分联系起来建立了数据库。植物的研究对于有机地球化学具有重要意义。
