| Abstract: | The isoprenoid alkanes present in a seep oil from Costa Rica have been examined using gas chromatography and mass spectrometry. In addition to the predominance of the C16 and C18-C20 regular isoprenoid alkanes, the C21 and C23-C25 regular isoprenoid alkanes were identified. The C26, C28 and C30 regular isoprenoid alkanes were tentatively identified. No evidence for the regular C17, C22 or C27 isoprenoid alkanes was found. The compounds 3,7,11- trimethyltetradecane and 3,7,11-trimethylhexadecane were tentatively identified. It is suggested that a higher regular isoprenoid structure (or structures) is required in addition to phytol to account for the distribution of isoprenoid alkanes. |
