ABSTRACT OBJECTIVE Optimizing the water extraction technology of Xiangqin jiere granules. METHODS The orthogonal
test of 3 factors and 3 levels was designed, and comprehensive scoring was conducted for the above indexes by using G1-entropy
weight to obtain the optimized water extraction technology of Xiangqin jiere granules with water addition ratio, extraction time and
extraction times as factors, using the contents of forsythoside A, baicalin, phillyrin, oroxylin A-7-O-β-D-glycoside, wogonoside,
baicalein and wogonin, and extraction rate as evaluation indexes. BP neural network modeling was used to optimize the network
model and water extraction process using the results of 9 groups of orthogonal tests as test and training data, the water addition
multiple, decocting time and extraction times as input nodes, and the comprehensive score as output nodes. Then the two analysis
methods were compared by verification test to find the best water extraction process parameters. RESULTS The water extraction
technology optimized by the orthogonal test was 8-fold water, extracting 3 times, extracting for 1 h each time. Comprehensive
score was 96.84 (RSD=0.90%). The optimal water extraction
