Abstract

The invention relates to a content measuring method of a Chinese patent drug. The steps of the invention are that the chromatographic condition and the systematical employment and suitability test are the first step. The preparation of the solution for comparison is the second step of the invention. 3. After extracting by methyl alcohol, the extract solution of the preparation specimen is concentrated to the low alcoholic solution or the alcoholic-free solution. 4. After the purge process 3, the concentration solution of the extract solution is transferred to the macroreticular resin of a neutral alumina pole, wherein the lower portion is neutral alumina, and the upper portion is pre-treated macroreticular resin. The upper portion and the lower portion are washed by water and a grain alcohol solution of 10-25% sequentially, then the pole is eluted by the grain alcohol solution of 50-95%, and the eluent is collected and evaporated to dryness, further the residue is dissolved and has the constant volume and the filtration. The sequent filtration solution is achieved as the specimen solution. 5. According to the measuration, the solution for comparison of 10 mul and the specimen solution of 20 mul are precisely extracted separately, and the liquid chromatograph is injected, after measuring, the aim is achieved.
