目的优选无糖型半夏泻心颗粒最佳制备工艺。方法以黄芩苷、小檗碱含量和出膏率为指标，应用L9（34）正交设计和多指标综合评分法优选无糖型半夏泻心颗粒最佳水提取工艺；以成型性、制粒情况为指标，考察辅料、矫味剂的种类和配比。结果最佳提取工艺为黄连用70%乙醇提取后，药渣与处方中其他6味药混合，提取3次，第一次加9倍量水，煎煮1 h，第二次加8倍量水，煎煮1 h，第三次加6倍量水，煎煮0.5 h；最佳的辅料种类和比例为浸膏粉∶糊精∶可溶性淀粉∶甜味素=1∶0.6∶0.2∶0.015，85%乙醇为润湿剂。结论该工艺合理可行，适宜做无糖型半夏泻心颗粒的制备工艺。

〔Abstract〕Objectve To optimize preparation technology of sugar-free banxia Xiexin granules.M ethods Using the content of Baicalin，berberine，and the extract yield as indexes，L9（34）orthogonal design and multi-index grading method was used to optimize the extraction process with water of sugar-free Banxia Xiexin granules.granules formability and pelletization as indexes，the types and combination ratio of accessories and corrigent were investigated.Results The best optimum extraction technology was as follows：Coptis Chinensis was extracted with 70%ethanol，residue and the other six kinds of herbs in the prescription was extracted for three times：9 times water for 2.5 h at the first time，8 times water for 1 h at the second time，6 times water for 0.5 h at the third time.The optimal ratio of extraction-dextrine-soluble starch-sweeteners was 1∶0.6∶0.2∶0.015，the wetting agent was 85%ethanol.Conclusion The process is reasonable and feasible，and it is suitable for the preparation process of sugar-free Banxia Xiexin granules.

半夏泻心汤是《伤寒论》中治疗脾胃病的经典名方，由半夏、黄芩、黄连、干姜等7味药组成，其功效为寒热平调，消痞散结，临床上用于治疗急慢性胃炎、消化道溃疡、急性胃肠炎［1-2］，现代研究表明其对糖尿病性胃轻瘫、胃癌等有明显的疗效［3-4］。但汤剂煎煮耗时，服用麻烦，不易携带。为方便患者服用，本实验探索将其制成无糖型颗粒剂，考察提取工艺、成型工艺进行，以确定最佳制备工艺，为其进一步研究、生产和临床应用提供依据。……
