| TITLE： | |
| 摘要： | 目的：优化当归粉制备工艺，筛选其最优粉碎粒径。方法：以挥发油和阿魏酸含量为指标，筛选当归药材的最优干燥温度、干燥时间和粉碎粒径，并模拟市售包装考察不同粒径下当归粉的稳定性；同时进行制备工艺验证试验。结果：当归药材的最优干燥温度为60～70 ℃，最优干燥时间为4.5～5 h，粉碎成中粉；模拟市售包装下中粉的稳定性最优；制备工艺验证试验中平均挥发油含量为0.46 ml/g（RSD＝0.034％，n＝3）、平均阿魏酸含量为0.123 μg/ml（RSD＝0.026％，n＝3）。结论：优化的工艺稳定可行，粉碎为中粉后当归粉的稳定性最优。 |
| ABSTRACT： | OBJECTIVE： To optimize the preparation technology of Angelica sinensis powder and conduct screening for the optimal particle size thereof. METHODS： With the contents of volatile oil and ferulic acid as the indexes， screening was conducted for the optimal drying temperature， dry welding time and particle size of the crude drug A. sinensis， and the stabilities of the A. sinensis powder with different particle sizes which was packed by simulating that sold in the market were investigated. The verification tests on the preparation technology were conducted. RESULTS： The optimal conditions for preparing the crude drug A. sinensis were as follows as drying temperature of 60-70 ℃， drying for 4.5-5 hours and being crushed into moderate-sized powder； the stability of the moderate-sized powder which was packed by simulating that sold in the market was the best. In the verification tests on the preparation technology， the average content of the volatile oil was 0.46 ml/g， with RSD of 0.034％ （n＝3）； the average content of the ferulic acid was 0.123 μg/ml， with RSD of 0.026％ （n＝3）. CONCLUSIONS： The optimized technology is stable and feasible， and the stability of the moderate-sized A. sinensis powder is the best. |
