摘　　要：采用水蒸汽蒸馏法从红花天料木叶中提取挥发油，用气相色谱-质谱连用技术对对红花天料木叶挥发油的化学成分进行分析，用峰面积归一化法得到各组分在挥发油中的相对含量。结果测得红花天料木叶中挥发油的含量为0．19％。从该挥发油中鉴定了31种化学成分，占挥发油总成分的72．31％。其中十八烷占23．96％，16·三十一酮占16．67％，γ-谷甾醇占13．13％，N，N-二苯氨基脲占3．29％，还有叶绿醇占2．69％，丁基异丁基邻苯二甲酸酯占2．50％等其它少量化合物。The volatile oils from leaves of Hornalium hainanense were extracted by steam distillation, and the chemical constituents were separated and identified by GC-MS. The contents of these constituents were determined using square peak to normalization. The results showed that the average oil yield obtained accounting for 0.19%. Thirty-one chemicals were identified,which constituted about 72.31% of the total volatile oil. Constituents were identified as Oetadecane 23.96%, 16-Hentriaeontanone 16.67%, γ-Sitosterol 13.13%, N, N-Diphenyl-hydrazinecarboxamide 3.29%, and other a few compounds Phytol 2.69% ,Butyl isobutyl phthalate 2.50% etc.
