Abstract:

To optimize the preparation process of oral liquid of fermented Polygala japonica Houtt., an orthogonal design was adopted and optimized the process of preparation process in oral liquid of fermented Polygala japonica Houtt.. The index of orthogonal experiment in apparent grade was determined to study the influence made by different preparation processes of oral liquid of fermented Polygala japonica Houtt. upon the color and the clarity. The optimum conditions for oral liquid of fermented Polygala japonica Houtt. by orthogonal test optimized process were as follows: water for eight times the quantity of medicinal materials in the process of decoction, pH with 7.0 and 10 hours. The result of this experiment was reliable. The clarity of the oral solution prepared by the optimized process was better. Manufacturing process consumes shorter time, so it was propitious to the batch production.
