Abstract:
The studies on the extract processes of Radix Aucklandiae and Rhizoma Coptidis, and the preparation method for Xianglian Drop Pills have been carried out. The preparation method included the adsorption of volatile oil of Radix Aucklandiae with the extract mixture of Radix Aucklandiae and Rhizoma Coptidis. Water in adequate amount was added into the above mixture, The mixture was grinded into homogeneous pasty, then added with melted PEG 4000. After being mixed well on water bath the mixed melt was poured into the home-made drop pill apparatus(at 90℃) preheated, dropped into dimethyl silicone at rate of 24 drops/min through the drop head with internal apeture for 45mm and external apeture for 6. 1mm、and cooled well. The drop pills were obtai ned by removal of dimethylsilicone. Every examination of prepared drop pills coincided with the requests in general notice of drop pills in Pharmacopoeia of the Republic of China(1990). The in vitro antibacterial test showed that Xianglian Drop Pills had the same antibiotic effect as Xianglian Pills did.
