目的 应用数学模型研究燀苦杏仁标准汤剂质量与其饮片中指标成分苦杏仁苷含量之间的相关性。方法 制备燀苦杏仁标准汤剂，利用Design-Expert 8.0.6软件建立饮片出膏率、标准汤剂中苦杏仁苷含量、苦杏仁苷转移率分别与饮片中苦杏仁苷含量之间的3个线性回归模型。结果 燀苦杏仁饮片出膏率为8.97%～12.12%；标准汤剂中苦杏仁苷含量为21.74%～30.32%；苦杏仁苷转移率为70.39%～90.54%。建立的3个线性回归模型R²均大于0.8，各项偏回归系数检验P值均小于0.05，具有显著性。3个线性回归模型均具有较好的准确性，预测值和实测值的相对偏差不大于10%，平均相对偏差不大于5%。结论 该研究可预测不同燀苦杏仁饮片制备所得标准汤剂的质量，为制定其标准汤剂的质量标准提供一定参考价值。

Objective To explore the relevance between the quality of standard decoction and the marker component amygdalin of decoction slices of blazing Armeniacae Semen Amarum(BASA) by mathematical model.Methods The BASA standard decoction was prepared, and three linear regression models of the amygdalin content and dry extract rate, the content of amygdalin in standard decoction and decoction slices, and the transfer rate in standard decoction and the content of amygdalin in decoction slices were established by using Design-Expert 8.0.6 software, respectively.Results The dry extract rate of BASA was 8.97%-12.12%;The content of amygdalin in standard decoction was 21.74%-30.32%;And the transfer rate of amygdalin was 70.39%-90.54%.The R² values of three linear regression models were all greater than 0.8.The P values of each partial regression coefficient were less than 0.05, which indicated that the three models were significant.Then the accuracy of three linear regression models was verified.The relative deviation between the predicted and measured values was less than 10%, and the average relative deviation was not greater than 5%.Conclusion The models established in this study could predict the quality of standard decoction prepared from different BASA, and provide a certain reference value for the establishment of standard decoction quality standard.
