OBJECTIVE To search for the optimal process of Flos Lonicerae in producing area, in order to offer scientific and applied process method for steadying the quality of Flos Lonicerae. METHODS To summarize and use for reference the reported process method, searching for the relativity of different processes and quality. RESULTS The content of Chlorogenic Acid in kill-enzyme torrefaction sample was 12. 8% higher than directly dried in the sun and 24.9% higher than dried in the shade. The content of Luteolin-7-glu in kill-enzyme torrefaction sample was 7.8% higher than the directly dried in the sun and 54.3% higher than dried in the shade. CONCLUSION At present, kill-enzyme torrefaction is the optimal process of Flos Lonicerae in producing area It is an important technology in GAP large-scale of Flos Lonicerae.
