Abstract: A new unknow n compound(arbitrarily labelled”E here) was detected out in sediments and conden-sates from the Ying-Qing Basin, South China Sea. The component is in significantly high abundance in certain samples, and it elutes after 17β(H)一22, 29, 30-trinorhopane in m /z 191 fragmentogram and justafter C28 5α(H),17α(H),21α(H) sterane(22S) in m/z,218 fragmentogram. The spectrum of ompound”E”indicated that compound E is a C29 tetracyclic compound. GC/M S/M S analysis demonstrated thatfragment ions at m /z 191, 218 and 273 do belong to the compound”E".To the best of our knowledge,the compound E is first reported too ccur in sedimentary records. The presence of the compound E is in-ferred to be related to marine organic matter input, which may be a product of specific algal precursorsin a trophic marine depositional environment. In addition to environment significance, the relative con-centration of the compound E in rock extracts was observed to be dependent on the maturity of rocks.
