摘　　要：工艺设计赋予产品质量内涵,探讨穿心莲制剂制备过程中化学指纹图谱变化及其与药效活性间的相关性,构建关键工艺环节与质量属性的桥梁。参照穿心莲制剂制备过程(提取-浓缩-干燥-制粒),HPLC指纹图谱测试各中间体微观组分物质基础差异,聚类分析结果提示提取环节对穿心莲制剂质量内涵变异影响较大;DPPH抗氧化、脂多糖(LPS)诱导小鼠腹腔巨噬细胞抗炎活性建模测定各中间体药效活性,均不断下降,分别绘制关键工艺参数与药效活性间曲线方程,结果均表明传统高温处理过程,不利于其临床疗效的发挥。利用偏最小二乘法对色谱-药效活性数据构建谱效模型方程,经验证,该方程能准确预测指纹信息与药效活性关系,便于后续质量属性评价及为进一步全过程质量控制提供科学依据。Process design grants the quality connotation to products. This paper was to investigate the correlation between changes of chemical fingerprints of Andrographis Herba preparation and its pharmacological activity, and set up the bridge between key process and quality attributes. By referring to the preparation process of AndrogTaphis Herba. preparation （ extracting-concentrating-drying- granulation）, HPLC fingerprints were employed to determine the difference of the effective materials of the intermediate micro compo- nents. Cluster analysis results indicated that the extraction link had great influence on quality connotation variation of Andrographis Herba preparation. The pharmacological activity of various intermediates was continuously decreased in the models of DPPH antioxidant activity and LPS-induced anti-inflammatory activity in mice peritoneal macrophages. Traditional high temperature treatment process was detrimental to its clinical effect from the curve equation between the key process parameters and pharmacodynamic activity. Partial least square （PLS） was used to construct spectrum-efficiency model equation, and it was verified that this equation could accurately predict the relationship between fingerprints and pharmacological activity, which would facilitate the subsequent evaluation of quality attributes and provide scientific basis for further quality control of the whole process.
