Abstract
OBJECTIVE: To study the volatile constituents of Loranthus delavayi. METHODS: The volatile constituents were extracted by steam distillation and supercritical CO2 fluid extraction, and the chemical compositions were analyzed by GC-MS techniques. RESULTS: Sixty-one peaks were separated and 41 of them were identified, accounting for 81.15% of the total content from the extracts of steam distillation; Ninty-tuo peaks were separated from the extracts of supercritical CO2 fluid extraction, and 46 of them were identified, accounting for 63.31% of the total content. CONCLUSION: There are great differences between the chemical compositions of the volatile constituents extracted by steam distillation and supercritical CO2 fluid extraction.
