目的 以热毒宁注射液的金银花提取浓缩工段为研究对象，使用过程性能指数（PPI）评价金银花提取浓缩中间体质量的可靠性和批间质量一致性。方法 收集一定时间内热毒宁注射液金银花提取浓缩工段中间体质量控制指标（新绿原酸、绿原酸、隐绿原酸、咖啡酰奎宁酸质量分数和固含量）的历史数据，使用PPI P_PK对其评价，并结合Bootstrap算法计算PPI的置信区间。结果 新绿原酸、绿原酸、隐绿原酸、咖啡酰奎宁酸质量分数和固含量的P_PK分别为1.115 6、1.111 2、1.117 9、1.110 9和1.560 0，固含量的过程生产能力最高，几种酚酸的能力次之，但均满足工段生产的要求，表明该工段中间体的可靠性和批间质量一致性较好；各个质量控制指标95%置信区间的下限分别为1.068 3、1.049 6、1.066 7、1.052 1、1.495 2，均大于1.000 0，说明分析结果较为可靠。结论 该方法可用于热毒宁注射液金银花提取浓缩工段生产能力评价和质量一致性的量化研究，为后续建立质量放行标准和工艺参数放行标准提供判断的依据。

Objective To evaluate the probability and quality consistence of Lonicera japonica Flos extraction and concentration intermediate by introducing and applying process performance index (PPI) P_PK. Methods With the historical quality analysis date of intermediate of Lonicerae Japonicae Flos extraction and concentration process of Reduning Injection., the confidence intervals of P_PK were estimated based on the Bootstrap sampling methods. Results The P_PK of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeoylquinic acid, solid holdup was 1.115 6, 1.111 2, 1.117 9, 1.110 9, and 1.560 0 respectively. The P_PK of solid holdup is the highest, the P_PK of several phenolic acids is lower, but all the P_PK can meet the production requirements, showed that the probability and quality consistence of this process is good. The lower limit of 95% confidence intervals of quality indexes was 1.068 3, 1.049 6, 1.066 7, 1.052 1, and 1.495 0 respectively, all greater than 1.000 0, indicating the results were credible. Conclusion The method can be used to evaluate the probability and quality consistence of Lonicerae Japonicae Flos extraction and concentration process, and it provides fundamental evidence on establishing quality standards for releasing or process parameters for releasing.
