METHODS The inclusion compound was prepared by saturated solution method. The multiple factors and levels experiments were done by orthogonal experiments design with the recovery of inclusion complex and the content of phenylpropanol as criteria. 方法采用饱和水溶液法,以包合物的收率和苯丙醇含量为考察指标,通过正交实验设计,综合平衡后确定最佳制备工艺。
AIM: To provide theoretical foundations for improvement on the dosage form of phenylpropanol by studying the inclusion of phenylpropanol/ β-CD and the influence of ethanol and magnesium stearate on it. 目的:研究苯丙醇与β-环糊精包合作用,探讨乙醇和硬脂酸镁对其包合作用的影响,为改进苯丙醇药物剂型提供理论基础。
Objective: To set up a new method for the determination of phenylpropanol and propiophenone in phenylpropanol soft capsules by GC-MS. 目的:建立了GC-MS法测定苯丙醇胶丸中苯丙醇含量及其杂质苯丙酮的含量。
Holocellulose is very significantly and positively correlated with the yield rate of gross pulp and fine pulp, and significantly or very significantly and negatively correlated with the content of the extracted substance from Phenylpropanol, the substance from cold water, arabinose content and the hardness of pulp. 综纤维素含量与粗浆得率、细浆得率呈极显著正相关,与苯醇抽出物含量、冷水抽提物含量、阿拉伯糖含量和浆的硬度呈极显著或显著负相关。
