THERMAL ALTERATION OF ORGANIC MATTER IN RECENT MARINE SEDIMENTS II ISOPRENOIDS

摘要

A series of isoprenoid compounds were isolated from a heat-treated marine sediment (from Tanner Basin) which were not present in the original sediment. Among the compounds identified were:phytol, dihydrophytol, C18-isoprenoid ketone, phytanic and pristanic acids, C19- and C20-monoolefines, and the alkanes pristane and phytane. The significance and possible routes leading to these compounds is discussed.
