The chemical composition of the elaiosome of Sloanea hemsleyana (Elaeocarpaceae) was analyzed by gas chromatographymass spectrometry. The relative content of each compound was determined by area normalization. Eleven compounds were identified, accounting for 97.6% of the total oil composition. The major compounds were Palmitic acid (36.0%) and Oleic acid (35.0%), which were favour food for ant. And it was demonstrated that the seed of S.hemsleyana can be dispersed by ant Pheidole sp. in the habitat of Kunming Botanical Garden. As for the defensive function of elaiosome of S.hemsleyana need to be identified in field.

Key words: Sloanea hemsleyana, Elaiosome, GC-MS, Myrmecochorous plant
