Abstract:	Lipid fraction and cell-wall materials have been separated from three types of algae (blue green, Microcystis sp.; green, Scenedesmus sp. and diatomaceous Diatoma sp.) and their KMnO₄ oxidation products (aliphatic $α,ω-C_{2} -C_{12}$ dicarboxylic acids; aliphatic normal C₁₄–C₂₄ monocarboxylic acids; benzoic acid and C₁₈ isoprenoidal ketone) examined by gas chromatography and gas chromatographymass spectrometry. The results suggest that the lipid material could make a greater contribution to polymethylene chains in kerogen than the cell-wall material, when the kerogens are mainly derived from algal components.
