Abstract
Compositional data on the sterol and alcohol fractions isolated from deep-sea marine sediments from the Okinawa Trough were obtained to determine the relative contribution from marine and terrestrial inputs. Following extraction, the sterol plus alcohol fraction was isolated by layer chromatography, derivatized with BSTFA and then analysed by capillary GC and GC—MS. A suite of C26−C29 stenols and stanols and C30−C32 keto—alcohols were identified in the sediments. The thermal stability of the compounds in these sediments was studied by heating portions of the surface sediment in glass tubes for 16 hours at temperatures from 50°C to 200°C. The C27 stanol/stenol ratio increased when temperatures went up to 175°C, but the distribution of C30−C32 Keto—alcohols remained unaffected. At 200°C most of the sterols and Keto—alcohols were destroyed.
