[Methods] Orthogonal test( L_(16)(4~3)) was designed to investigate the optimal soaking time,decocting time and bean curd proportion for processing Aconiti Kusnezoffii Radix by bean curd. The contents of monoester alkaloids and diester-alkaloids were measured as the evaluation indexes. [Results]The contents of monoester alkaloids were 0. 11%,0. 07%,0. 062% and 0. 048% respectively under the four levels of soaking time,were0. 081%,0. 066%,0. 074% and 0. 067% respectively under the four levels of decocting time,and were 0. 070%,0. 072%,0. 080% and0. 073% respectively under the four levels of bean curd proportion. The content of diester-alkaloids was all below 0. 034%. The influence intensity of the three factors on the content of monoester alkaloids ranked as soaking time > decocting time > bean curd proportion. Under any of the above conditions,the content of diester-alkaloids was below the limit of Chinese Pharmacopoeia. The content of diester-alkaloids was reduced obviously with the increased use of bean curd. [Conclusions] The optimum processing conditions for Aconiti Kusnezoffii Radix were A_3B_3C_2,i. e.,soaking time of 6 d,decocting time of 5 h and bean curd proportion of 25%.展开更多
