微粉硅胶

结果提取液相对密度控制在1.15~1.20（60℃热测），60℃~70℃保温，加入微粉硅胶可以明显降低浸膏粉的吸湿性。

RESULTS The relative density of the extract was between 1.15-1.20 ( 60 ℃), and the temperature was between 60 ℃ 70 ℃ . Adding colloidal silicon dioxide could notably lower hydroscopicity of the extract .

不过微粉硅胶用量过大时，流动性反而降低。

However , when the silicon dioxide with excessive liquidity , the liquidity was reduced .

结果表明，当速释小丸中的尼群地平-HPMCP-微粉硅胶的比例达1∶2∶2以上时，溶出度迅速提高；

Theresults showed that the dissolution from fast-release pellets was significantly increased when the ratio of1-HPMCP-silicawas up to1 ∶ 2 ∶ 2 .

以丙烯酸树脂Ⅱ为囊材、微粉硅胶为抗黏剂、蓖麻油为增塑剂、95%乙醇为溶剂，采用喷雾干燥法制得麦冬皂苷肠溶微球。

Ophiopogon saponins enteric microspheres were prepared by spray drying technique with Eudragit ⅱ as coating material , castor oil as plasticizer and ethanol as solvent .

最佳处方为药物与囊材比例1∶4，蓖麻油用量1%，微粉硅胶用量1.5%。

The best prescription included the proportion between drug and enteric coating material ( 1 ∶ 4 ), the dosage of castor oil ( 1 % ), and the dosage of micronization silica gel ( 1.5 % ) .
