[Study on the chemical constituents of the volatile oil from aerial parts of Isodon eriocalyx var. laxiflora].
OBJECTIVE
To study the chemical constituents of the volatile oil from the aerial parts of Isodon eriocalyx var. laxiflora.


METHODS
The oil was obtained by hydrodistillation. The chemical compositions were separated and identified by GC-MS. The relative contents in the oil were determined by area normalization.


RESULTS
163 peaks were separated and 105 compounds were identified, constituting 85.68% of the total peak area.


CONCLUSIONS
105 compounds characterized by GC-MS analysis were found from I. eriocalyx var. laxiflora for the first time.
