  • Title: [Analysis of the chemical constituents of volatile oil from the Folium Rhododendri Daurici by supercritical CO2 extraction].
    Author: Jiao SQ, Liu FH.
    Journal: Zhong Yao Cai; 2009 Feb; 32(2):213-6. PubMed ID: 19504964.
    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.
