黄芩清肺口服液制备工艺研究

为了确定黄芩清肺口服液的制备工艺,根据处方药味所含成分的性质特点,进行了以下的研究工作:苦杏仁提取HCN的工艺研究;黄芩等药材水提正交试验,以黄芩苷作为定量检测指标,优选出黄芩等药材水提的最佳工艺是以12倍量水煎煮2次,每次1小时;乙醇沉淀工艺研究,确定了乙醇沉淀工艺为加入3倍药液体积的80%乙醇;药液澄明度稳定性工艺研究,通过向芳香水中加入聚山梨酯-80,对药液进行冷藏处理,调节药液的pH值,从而解决成品的澄清度问题.

Study on Preparation Technological Process of Huangqin Qingfei Koufuye

OBJECTIVE: To study the optimum preparation technological process of Huangqin Qingfei Koufuye for mass production. METHODS: The optimum technology of extraction HCN from Semen Armeniacae Amarum was selected by experiments; The optimum conditions for the extraction process was selected with orthogonal design, and the content of baicalin in the extract as marker was determined. RESULTS: The optimum technology of extraction HCN from Semen Armeniacae Amarum was as follows: crushing to pieces, adding 3 times amount of 37 degrees C water and soaking overnight, extracting and collecting 1.33 times amount of extract; the optimum extraction process wasas follows: extracting 2 times, each time adding 12 times amount of water and extracting 1 h. CONCLUSION: The preparation technological process can be used for mass production.
