Abstract:Objective The research on water extraction and alcohol precipitation process of qingyan oral liquid in order to provide the basis for large-scale of enterprise.Methods The transfer rate of irisflorentin and total glycosides were chosen as the assessment index. The optimum conditions were selected by the L9 (34) of orthogonal experiment.Results The optimal water extraction conditions were 10 times water of the amount of herb and immerse 0.5 h, extracted 3 times and 1.5 h per time. The optimum alcohol precipitation technology was extraction solution to concentrate income 1.5g/mL, solution containing methanol was 70%, standing 12 h with 15℃.Conclusion The extraction and alcohol precipitation process combined with enterprise-scale production, which owns theoretical and practical significance in purification technology of qingyan oral liquid.

清咽口服液处方来源于临床使用的经验方射干豆根桔梗汤,主要由射干、山豆根、桔梗、甘草等组成,临床用于预防和治疗上呼吸道感染及流感,疗效较好。处方中君药为射干,文献资料[1-2]表明,含射干的复方制剂多具有清利咽喉功能,常被用来预防或治疗上呼吸道感染感染及流感。由于汤剂服用量大,不方便携带,在使用上有一定的局限性,因此特将射干豆根桔梗汤开发成院内制剂清咽口服液。根据药材成分、药理作用、中药用药习惯和临床疗效,为最大限度提取和保留该经验处方的活性成分,实验采用水提醇沉工艺制备清咽口服液。在前期工艺研究中,对影响水提工艺的影响因素(浸泡时间、提取次数、提取时间、加水量)和醇沉的影响因素(药液浓度、醇沉时间、醇沉浓度、醇沉温度)进行单因素考察,在此前提下进行正交设计,考察各影响因素的交互作用,实验以处方中君药射干的主要活性成分次野鸢尾黄素的转移率和总皂苷转移率作为评价指标,对清咽口服液的制备工艺进行优化,为下一步申报医院制剂提供依据。……
