[Optimization of the processing technology of Aconitum kusnezoffii Reichb. by orthogonal test]

A study on the processing technology of Aconitum kusnezoffii by orthogonal test was carried out by assaying as criteria the changes in contents of the total alkaloids and ester type alkaloids before and after processing. The optimum experimental conditions were obtained after treating the experimental data with a formula for the multiple criteria, and the optimal processing results were achieved by having the material macerated with water, cut into thick pieces and then steamed under high pressure (127 degrees C, 0.15MPa) for 3 hours.
