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

The distributions of n-alkanes of four species of Micromeria have the conve ntional higher plant pattern of high carbon preference index (CPI) and odd- numbered carbon dominance (maxima at n-C-31 or n-C-33), rather than the eve n-numbered predominance previously reported (Palic, R., Ristic, N., Simic, N., Kitic, D., Kapetanovic, R., 1997. The alkanes from some plants of Micro meria genus. Journal of the Serbian Chemical Society 62, 619-622). The stab le carbon isotope ratio values (delta(13)C) of the individual n-alkanes (-3 8 to -34 parts per thousand) are typical of C-3 plants. Homologous series o f odd-numbered predominant iso-alkanes (i-C-27 to i-C-35) and even-numbered predominant anteiso-alkanes (a-C-27 to a-C-35) are also present (8 to 18% of the total identified alkanes) and have similar carbon isotopic ratios (- 36.8 to -35.1 parts per thousand).
