Abstract:Objective: To study the volatiles from Elsholtzia splendens and Molsa chinese. Method: The volatile chemical constituents from E.splendens and M. chinensis. were analysed by HS-SPME-GC-MS. Result: Thirty-nine and forty-six components from E.splendens and M. chinese, which accounted for 70.55% and 92.44% of the peak areas, were separated and identified. Conclusion: The volatile chemical constituents have high application value in medicine and chemical industry and mainly consisted of alkane, olefin, alcohol, ketone, phenol, organic acid, etc. The present experiments provide a scientific basis for the further exploitation and utilization of this herb.
