摘　　要：采用水蒸气蒸馏法提取糖胶树叶的挥发油.运用气质谱联用(GC-MS)技术研究海南糖胶树叶的挥发油化学成分.并采用峰面积归一化法确定各成分的相对质量分数.结果共鉴定出36种成分,占总离子流出峰面积的94.83%.糖胶树叶挥发油主要有α-蒎烯(16.62%),2-丙烯酸丁酯(15.86%)和大根香叶烯D(13.37%).本研究可为糖胶树的进一步研究开发和利用提供基础研究数据.To investigate the chemical constituents of the volatile oil from leaves of Alstonia scholaris （ L. ） R. Br. in Hainan province, the volatile oil was extracted by water steam distillation and then ana- lyzed by GC-MS. The relative percentage contents of each component were determined by peak area normalization method. 36 compounds from the volatile oil were separated and identified, which occu- pied for 94.83% of total volatile oils. The main chemical constituents were ot-pinene（ 16.62%）, butyl acrylate （ 15.86% ） and germacrene D （ 13.37% ）. The present study of the volatile oil from the leaves of Alstonia scholaris （L.） R, Br. provides a chemical basis for a medicinal herb.
