摘要：
目的 优选中药复方制剂妇舒保凝胶的精制、浓缩及干燥工艺.方法 本试验以大黄酸、大黄素、大黄素甲醚总含量的保留率和纯度为评价指标,优选水提液精制工艺,以大黄酸、大黄素、大黄素甲醚总含量和盐酸小檗碱含量的转移率及干燥品外观性状为评价指标,比较常用的浓缩、干燥方法,优选出最佳浓缩、干燥工艺.结果 最佳精制工艺为0.2 g/ml水提液在70°C下加入ZTC1+1-Ⅱ型澄清剂B组分0.6 ml/g,搅拌10 min,70°C水浴保温30 min;再加入A组分0.3 ml/g,搅拌10 min,70°C水浴保温30 min;静置12 h,过滤.最佳浓缩、干燥工艺为在真空度为-0.08~-0.09 MPa,温度为60°C的条件下减压浓缩至相对密度约为1.05后,将浓缩液喷雾干燥.结论 优选出的妇舒保凝胶精制、浓缩、干燥工艺稳定可行、科学合理,可为大生产提供依据.%Objective To study the purification, concentration and drying technology of Fushubao gel. Methods The purification technology of Fushubao gel was optimizing by the total retention rate of Rhein, emodin, physcion and purity of content. The concentration, drying technology of Fushubao gel was optimized by the transfering rate of Rhein, emodin, physcion and Berberine hydrochloride. Results Best refining technology included in the condition of the water extract of 0.2 g/ml at 70 °C, the ZTC1+1-II clarifying agent B 0.6 ml/g was mixed10 min in a 70 °C water bath thermal insulation 30 min; And then agent A 0.3 ml/g was added and mixed 10 min in a 70 water bath thermal insulation 30 min; after 12 h, filter it. Best thickening, drying technology was in the vacuum for -0.08~-0.09 MPa, a temperature of 60 °C, the pressure was reduced to concentrate its relative density about 1.05 and concentrated liquid spray was dryed. Conclusions The purification, concentration and drying technology of Fushubao gel is reasonable, and can be used in the production.
