Even carbon number predominance of plant wax n-alkanes: a correction

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 (Pali , R., Risti , N., Simi , N., Kiti , D., Kapetanovi , R., 1997. The alkanes from some plants of Micromeria genus. Journal of the Serbian Chemical Society 62, 619–622). The stable carbon isotope ratio values (δ13C) of the individual n-alkanes (−38 to −34‰) 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‰).
