The distributions of n-alkanes of four species of Micromeria have the conventional higher plant pattern of high carbon preference index (CPI) and odd-numbered carbon dominance (maxima at n-C31 or n-C33), rather than the even-numbered predominance previously reported. The stable carbon isotope ratio values (d13C) of the individual n-alkanes (-38 to -34.permill.) are typical of C3 plants. Homologous series of odd-numbered predominant iso-alkanes (i-C27 to i-C35) and even-numbered predominant anteiso-alkanes (a-C27 to a-C35) are also present (8 to 18% of the total identified alkanes) and have similar carbon isotopic ratios (-36.8 to -35.1.permill.).
