RESUMO

Objective To improve the filtering technique and the addition methods of distillate for Tongtian oral liquid with a new type of filtering equipment. Methods The filter paper in the current filtering process was replaced with a combination of terylene filter cloth and pulvis talci. Distillate was added into the runny paste of preparation directly without using the solubilizer of Tween-80. Then the admixture was agitated sufficiently. After that, 10% NaOH was used to adjust the pH to 4.5-A.5, and the solution was added to 1200 L by water. At last, a clear preparation was obtained by using the above filtering equipment. Results Compared with the product made by the current method, the improved preparation was qualified and tasty. Conclusion The improved method is feasible, simple and economical. The product is tasty.
