摘　　要：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 A5 stenols and 5a- stanols mainly come from zoopiankton, algae and phytoplankton in marine environment. C29 24-ethylcholest- 5 - en- 3B- ol is thought to indicate input of terrigenous organic matter . The increase of C27 . C28 and C29 5a-stanol /5 stenol ratios with sediment depth shows the evolution of stenols and stanols in the marine sediment core .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 A5 stenols and 5a- stanols mainly come from zoopiankton, algae and phytoplankton in marine environment.
