[Analysis of the volatile constituents from Loranthus delavayi].

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.
