【摘要】 目的:比较不同干燥方法对大黄配方颗粒中蒽醌类成分的影响。方法:以总蒽醌含量,芦荟大黄素、大黄酸、大黄素、大黄酚和大黄素甲醚的总量为指标,对不同干燥方法进行考察。结果:喷雾条件为浸膏相对密度为1.06~1.10(60°C)进风温度140~150°C,出风温度85~90°C所得的颗粒外观较好,蒽醌类成分破坏最小。结论:大黄配方颗粒最佳的干燥方法是喷雾干燥。更多还原

【Abstract】 AIM: To compare the influences of drying methods on Radix et Rhizoma Rhei in Dispensing Granu- les . METHODS: The vaccum and spray methods were studied by determination of total anthraquinones and the sum of aloe-emodin, rhein, emodin, chrysophanol and physcion. RESULTS: When in spray drying conditions re- lative density of extract was 1.06 - 1.10 (60 °C) and entering wind temperature was at 140-150 °C, outlet wind temperature was at 85-90 °C. Radix et Rhizoma Rhei dispensing granules appearance was good, the total anthraquinones was destroyed least. CONCLUSION: Spray drying method for dispensinp granules has superiorily ever vaccum one.更多还原
