Abstract

This experiment aimed to study the profile of n-alkanes in tropical grasses species (Brachiaria brizantha, Cynodon dactylon and Panicum maximum) and legumes (Arachis pintoi and Glycine wightii). They were identified and quantified, through gas cromatography, the n-alkanes C24 to C35, being the alkanes C32 and C34 internal indices. The n-alkanes concentrations in the different species and respective fractions (leaf blade, stem higher and lower portion and dead matter for grasses; leaves, stem higher portion, stem lower portion and dead matter for legumes) were submitted to variance analysis and mean test (Tukey). For most of the species and fractions, there is prevalence of odd chain n-alkanes during springtime and winter. There was larger concentration of the alkanes C29, C31 and C33 in springtime, C27, C28, C29, C30 and C31 in summer and C27, C29, C31 and C33 in winter
