Study on the Preparation Process of Xiangsha Liu jun Granule / 中国药房

ABSTRACT

OBJECTIVE: To optimize the preparation process of Xiangsha Liujun Granule. METHODS: By the orthogonal design. taking the rates of recovery of volatile oil, Ginsenoside Re and qualified granules as the indexes, we optimized the oil extracting conditions, the decocting conditions and the conditions of granulation by spayer. RESULTS: The optimum oil ex- tracting conditions for four kinds of herbs(Pericarpium Citri Reticulatae etc.) were that water was 30 times of herbs in weight, soaking time was 3 hours and extracting time 15 hours. The optimum decocting conditions for four kinds of herbs(Fuling etc.) were that water was 15 times of herbs in weight, soaking time was 3 hours and decocting time 4 hours, herbs were decocted twice. The optimum conditions of granulation by sprayer were that the fliud extract was 2 times of Dextrin in weight, the rel- ative density of the fliud extract was 1. 30(measured at 25℃), the voltage of sprayer was 120 volts, the period of shaking bag was 65 times(shaking bag back and forth twice in each period). CONCLUSION: The results of the experiment make it clear that the preparation process of Xiangsha Liu jun Granule is stable and feasible.
