| 摘 要： | Significance of sterol compounds in studying bio- logical precursors, evolution and application of bio- markers in geological bodies and fossil fuels such as oil and coal resulted in a research upsurge during the 1970s―1980s, and a lot of papers were the…

| Abstract: | Various Δ5-3β-sterenols, whose carbon numbers range from C19-C23 to C26-C30 and some compounds have many stereomers maximal up to six, have been detected out from the extract of brown algae (Sargassum muticum), which means that steranes with lower carbon numbers are likely different in the origin, and some corresponding sterol stereoisomers
may have already existed in their precursor organisms. This provides some experimental evidence for supplementing and amending
the traditional interpretation of the sterol stereoisomer transformation during the deposition and diagenesis of organic matter. |
