Abstract

Ten stenols and stanols were identified by TLC, GC and GC-MS-DS in a marine sediment core from Beibu Bay, the South China Sea. C27, C28 and C29 Δ5 stenols and 5α-stanols mainly come from zooplankton, algae and phytoplankton in marine environment. C29 24-ethylcholest-5-en-3β-ol is thought to indicate input of terrigenous organic matter. The increase of C27, C28 and C29 5α-stanol/Δ5 stenol ratios with sediment depth shows the evolution of stenols and stanols in the marine sediment core.
