采用气相色谱-质谱联用技术对仿栗油脂体的化学组成进行研究,并用气相色谱面积归一化法对各成分进行了定量。从仿栗油脂体中得到11个化合物,占成分总量的97.6%,其中主要成分为十六烷酸(棕榈酸)和十八碳烯酸(油酸),分别占36.0%和35.0%。已有研究表明,这两种脂肪酸为蚂蚁所喜好。通过观察及实验证明,在昆明植物园,获得油脂体回报的大头蚁(Pheidole sp.)是仿栗种子的潜在传播者,而油脂体对其他取食者的趋避作用有待进一步的研究。

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
