摘要
测定16种中药制剂原料的吸湿特性参数和物理特性参数,采用主成分分析和偏最小二乘回归分析中药制剂原料的吸湿行为以及中药制剂原料的吸湿性与其他物理特性的关系。结果表明,含水量、粒径分布、水溶特性和黏聚力与平衡吸湿量、吸湿初速度、吸湿加速度均有较好的相关关系。其中平衡吸湿量与含水量、粒径分布、水溶特性和黏聚力呈正相关;吸湿初速度与含水量、粒径分布、凸起度呈负相关,与水溶特性和黏聚力呈正相关;吸湿加速度与含水量、粒径分布呈正相关,与水溶特性和黏聚力呈负相关。从物理因素角度分析了中药制剂原料的吸湿特性。
Material properties and hygroscopicity were determined. Principal component analysis and partial least squares regression were applied to evaluate relationships between material properties and hygroscopicity of Chinese medicine raw materials. The results showed that hygroscopicity was corrdated with water content, particle size distribution, water soluble characteristic and cohesion. Balanced moisture content was positively correlated with water content, particle size distribution, water soluble characteristic and cohesion. Moisture absorption velocity was negatively correlated with particle size distribution, protruding degree and positively correlated with water soluble characteristic and cohesion. Moisture absorption acceleration was positively correlated with water content, particle size distribution and negatively correlated with water soluble characteristic and cohesion. Hygroscopicity of Chinese medicine raw materials is interpreted in terms of physics.
