目的
2
研究粉碎制粒法在中药临方颗粒剂生产中的应用,优化制粒工艺,提高颗粒得率和质量,分析颗粒性质与干浸膏物理性质及处方组成的相关性,建立适用于临方颗粒剂生产的高效制粒方法。
方法
2
以中药临方干浸膏为研究对象,采用粉碎制粒法制备颗粒,考察筛网类型(刀孔型、圆孔型)、筛网孔径(1.27、1.57、2.00 mm)及转刀转速(1 000、2 000、3 000 r/min)对颗粒得率的影响。测定干浸膏的吸湿性、表观密度、软化点等物理性质以及颗粒的粒度分布、溶化性、硬度、休止角等,进行相关性分析,探讨干浸膏物理性质与颗粒性质的关系。
结果
2
刀孔型筛网所得合格颗粒比例高,颗粒均匀度好。筛网孔径2.00 mm、转速2 000 r/min时,颗粒得率最高,均在75%以上,且50%的处方颗粒得率超过85%。颗粒得率、硬度、溶化时间与干浸膏表观密度呈正相关,颗粒休止角与干浸膏吸湿性、表观密度呈负相关。糖性料中药占比较高的处方,其干浸膏吸湿性较强,表观密度较高,所得颗粒硬度较大。
结论
2
粉碎制粒法可用于中药临方颗粒剂的制备,能有效提高颗粒得率和质量。干浸膏的物理性质受处方组成影响,并进一步影响颗粒性质。研究结果可为临方颗粒剂的制备工艺优化及质量控制提供实验依据。
Objective: To study the application of the crushing granulation in the production of personalized traditional Chinese medicine (TCM) granules, optimize the granulation process, improve granule yield and quality, analyze the correlation between the granule properties and the physical properties of dried extracts as well as the prescription composition, and establish an efficient granulation method suitable for the production of personalized TCM granules.
Methods
2
The dried extracts of personalized TCM prescriptions were used as the research subjects. The granules were prepared using the crushing granulation method. The effects of sieve type (knife-hole, and round-hole), sieve aperture (1.27, 1.57, and 2.00 mm), and cutter speed (1 000, 2 000, and 3 000 r/min) on granule yield were investigated. The physical properties of the dried extracts, such as hygroscopicity, apparent density, and softening point, as well as the particle quality, including particle size distribution, solubility, hardness, and angle of repose, were detected. Correlation analysis was carried out to explore the relationship between the physical properties of the dried extracts and the properties of the granules.
Results
2
Granules were produced with a higher proportion of qualified granules and better uniformity using the knife-hole sieve. When the sieve aperture was 2.00 mm and the cutter speed was 2 000 r/min, the granule yield was the highest, exceeding 75% and with 50% of the prescription granules achieving a yield of over 85%. Granule yield, hardness, and dissolution time were positively correlated with the apparent density of the dried extracts, while the angle of repose of granules was negatively correlated with the hygroscopicity and apparent density of the dried extracts. The dried extracts of the prescriptions with a higher proportion of sugary material exhibited stronger hygroscopicity, higher apparent density, and greater granule hardness.
Conclusion
2
The crushing granulation method can be applied in the production of personalized TCM granules, and effectively improve the granule yield and quality. The physical properties of the dried extracts are influenced by the prescription composition, and further affect the granule properties. The results of this research provide an experimental basis for the optimization of preparation process and quality control of personalized TCM granules.
