[Analysis of the chemical constituents of volatile oil from the Folium Rhododendri Daurici by supercritical CO2 extraction].

Jiao Shu-qing, Feng-hua Liu

Abstract

OBJECTIVE: To compare the chemical constituents of volatile oils from Folium Rhododendri Daurici between supercritical CO2 extraction (SCE-CO2) and steam distillation (SD). METHODS: The chemical constituents of volatile oils obtained by two methods were analyzed by GC-MS. RESULTS: 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. CONCLUSION: The chemical constituents obtained by SCE-CO2 and SD are approached.
