          摘  要  目的  优化香芩解热颗粒的水提工艺。方法  以加水倍数、提取时间、提取次数为考察因素,以连翘酯苷A、黄芩苷、连翘
          苷、千层纸素A-7-O-β-D-葡萄糖醛酸苷、汉黄芩苷、黄芩素、汉黄芩素含量和出膏率为评价指标,设计3因素3水平的正交实验,并
          利用G1-熵权法对上述指标进行综合评分,得正交实验优化的水提工艺。以9组正交实验结果为测试和训练数据,以加水倍数、提
          取时间、提取次数为输入节点,以综合评分为输出节点,利用BP神经网络建模进行网络模型优化和水提工艺寻优。验证并比较两
          种方法所得水提工艺参数,确定香芩解热颗粒的最佳水提工艺。结果  香芩解热颗粒经正交实验优化后的水提工艺为加水倍数8
          倍、提取次数3次、提取时间1 h,综合评分为96.84分(RSD为0.90%)。BP神经网络建模优化后的水提工艺为加水倍数12倍、提取
          次数4次、提取时间0.5 h,综合评分为92.72分(RSD为0.77%),略低于正交实验所得工艺。结论  本研究成功优化了香芩解热颗
          粒的最佳水提工艺,具体为加水倍数8倍、提取次数3次、提取时间1 h。

          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
