摘要：

A molecular sieve method using NaX (13X) has been used to separate macrocyclic alkanes (in the carbon number range C-14-C-34), markers of the freshwater alga Botryococcus braunii, from the branched/cyclic hydrocarbon fractions of sediments and crude oils. The macrocyclic alkanes were included in the 13X sieve and were recovered by HF digestion. (C) 2004 Elsevier Ltd. All rights reserved.
