辅料因素对双黄连微囊吸湿量与分散性的影响

目的:研究辅料因素对双黄连微囊吸湿时吸湿量与分散性的影响。方法:单因素考察,检测不同囊材、抗粘剂以及原辅料配比制成双黄连微囊吸湿后的吸湿量与分散性。结果:样品吸湿导致分散性降低,但常常吸湿量大的样品分散性仍较好。结论:在防潮技术研究中,不仅要检测样品的吸湿量,也需要考察样品吸湿后的分散性。

Influence of Excipients on Moisture Absorption and Dispersibility of Shuanghuanglian Microcapsules

Objective: To study the influences of excipients on the moisture absorption and dispersibility of Shuanghuanglian microcapsules.Methods: Shuanghuanglian microcapsules were prepared with different wall materials,antisticking agents and ratio of medicinal materials to exipients,and the moisture absorption and dispersibility of the microcapsules were determined.Results: The dispersibility of Shuanghuanglian microcapsules weakened with the increasing of moisture absorption,but some samples were of good dispersibility in spite of the high moisture absorption.Conclusion: During the research on the dampproof technologies,not only the moisture absorption,but also the dispersibility of samples should be investigated.
