This paper established a method for the determination of ginsenoside Rg1 in Jiangtangning capsules.Ginsenoside Rg1 was determined by a dual-wavelength TLC scanning method with 525 nm and 700 nm as the detective wavelength.The results showed that there was a good linear relationship from 0.323 to 2.584 μg for ginsenoside Rg1 (r = 0.9995), and the average recovery rate was 98.06% (RSD = 1.33%, n = 5).In conclusion, the method is simple and accurate, and can be used for the quality control of Jiangtangning capsules.

The aim of this study is to establish a rapid method for the determination of intermediate in mannitol injection.The content of intermediate in mannitol injection was determined by polarimetry.The method was simple, rapid and accurate.The average recovery was 100.2%, RSD being 0.17%(n=5).The method can be used for the content determination of intermediate in mannitol injection.

The preparation of ornidazole transfusion was studied.Checking the character and pH value and related material and content of ornidazole transfusion, we optimized the solution temperature and the pH value and sterilization conditions.The best preparation of ornidazole transfusion was that the solution temperature was 45 degree C, the pH value was about 3.3 and sterilization conditions was 115 degree C and 30 min.The best preparation of ornidazole transfusion was chosen.
