A Chemotaxonomic approach to the alkane content of three species of Anthocleista Afzel. (Longaniaceae).

The chemotaxonomic significance of leaf wax n-alkanes was studied in three species of Anthocleista Afzel. Identification of alkane components were determined by Gas chromatography (GC) and Gas chromatography Mass Spectrometry data (GC-MS). In all, fourteen alkanes were identified, ranging from Tetracosane (C24H50) to Heptriacontane (C37H76). Tetracosane, Pentacosane and Heptriacontane were the major components in all the three species of Anthocleista. A. djalonensis A. Chev. and A. vogelii Planch. were characterized by high percentages of Tetracosane (28.81% and 39.14% respectively), whereas in A. nobilis, Heptriacontane (C37H76) was the major component being 24.76%. Significant correlation between A. djalonensis and A. vogelii at 0.01 implies a probable closeness between these species. However, the result obtained in this study provides further evidence of chemotaxonomic significance.
