Dear Organic Geochemists,

I would appreciate any help in the identification of an homologous series
of compounds. We found them in the lipid extract of a lacustrine sediment
separated on a MacCarthy-Duthie column eluted by heptane-toluene 9:1.
On GC-MS it gave about eight peaks. One of them had the following
characteristics :
RT : 37.28min eluting just after nC23.
Base peak : 67
Molecular mass (supposed) : 292
Relative intensities : 41(30),
55(50),67(100),81(90),96(40),110(18),124(30),138(20),152(10),166(5),180(10),
194(5),208(7),222(3),236(10),250(5),264(5),278(0),292(10).

Many thanks in advance for any identification or advice.

Jérémy
