采用超临界萃取 /气相色谱 -质谱技术测定了广东茂名油页岩中环己烷的链取代烃、甾烷、甾烯和藿烷等生物标志物 ,其分析结果与经典索式抽提和文献结果基本相符。该方法与索式抽提法相比简单、快速、无污染和危险 ,可用于油页岩等固体样品中生物标志物的分析 The biomarkers of cyclohexane chain-substituted hydrocarbons, steranes, steroids and hopane in Maoming oil shale from Guangdong were determined by supercritical fluid extraction and gas chromatography-mass spectrometry. The analytical results were in good agreement with the results of classical sorption extraction and literature results Basic match. This method is simple, rapid, non-polluting and dangerous compared with Soxhlet extraction and can be used to analyze biomarkers in solid samples such as oil shale
