We studied the extraction process of Tongluo external granules and optimized the extraction process.With the extraction rate as the evaluation index,the water amount,extraction time and extraction times as the fac-tors,the L9(34)orthogonal test was used to optimize the extraction process.The optimum extraction process was ob-tained as follows:adding 10 times of water,extracting for 1 h each time,and extracting for 3 times.The results of variance analysis showed that the water amount and the extraction times had significant influence on the extraction rate.The extraction process of Tongluo external granules is stable and reliable.
