To compare the chemical constituents of volatile oils from Folium Rhododendri Daurici between supercritical CO2 extraction (SCE-CO2) and steam distillation (SD).
The chemical constituents of volatile oils obtained by two methods were analyzed by GC-MS.
52 compounds in the volatile oil extracted by SCE-CO2 and 48 compounds in the volatile oil extracted by SD were separated and identified separately. There were 45 same components.
The chemical constituents obtained by SCE-CO2 and SD are approached.
比较超临界CO₂萃取法（SCE-CO₂）和水蒸气蒸馏法（SD）提取兴安杜鹃叶挥发油的化学成分。
采用气相色谱-质谱联用（GC-MS）法分析两种方法所得挥发油的化学成分。
SCE-CO₂萃取所得挥发油分离鉴定出52种化合物，SD法所得挥发油分离鉴定出48种化合物，两者共有45种相同成分。
SCE-CO₂法和SD法所得化学成分相近。
