Objective: To ascertain the process conditions for extracting the volatile oil from kangchi Capsules. Methods: The effects of water adding amount and extraction time on the yield of volatile oil were studied. The extraction condition of percolation was established with the extract yield and extraction transfer rate of tanshinone Ⅱ A as markers and the optimum condition for reflux method also was selected with the orthogonal test. Results: The volatile oil of Rhizome Acori Graminei could be basically extracted when it was extracted for 5 hours with 12 times of water. Radix Salviae Miltiorrhizae and Radix Polygalae could be effectively extracted with the peocolation and reflux methods in 90% alcohol as a solvent. But the percolation method used less energy consumption and solvent than refluex method. So the production cost was lowered. Conclusion: The experimental results provide the basis for the ascertainment of extraction process of kangchi Capsules.
