ABSTRACT
Objective: To investigate the new processing method of Arisaema Amurense Maxim. Methods: Referring to hot and and tingle taste, we have screened out the best condition in processing Arisaema Amurense Maxim. by testing in orthogonal designs, and compared stimulation, extractives and UV of different samples. Results: The new processing method can save half slum according to Ch P. the stimulation of the two samples processed by Ch P & by new method is similar; the water soluble and ethanol soluble extractives and UV of processed samples by new method is better than that by Pharmacopoeia of PR. China. Conclusion: The new method screened out by testing in orthogonal design, can not only eliminate hot and tingle taste, reduce the lose of effective component, but also save a lot of slum.
