| titleOfInvention | Determination method for tanshinol content in Naozhengning preparation |
| abstract | The invention provides a determination method for tanshinol content in a Naozhengning preparation. Salvianic acid A sodium in the preparation is extracted by using a methanol-glacial acetic acid or methanol-trifluoroacetic acid solution to prepare a solution for test products, octadecylsilane chemically bonded silica chromatographic column is adopted, the methanol to 0.01-0.2 percent of trifluoroacetic acid solution, which equals to (5:95) to (20:80), is used as a mobile phase for carrying out high performance liquid chromatographic analysis, the chromatographic peak of the salvianic acid A sodium is determined the in the position of 280 nm wave length, and the tanshinol content is calculated through an external standard method. The determination method for the tanshinol content, established in the invention, has strong specificity, the linear relation is good, the accuracy is high, the repeatability is good, the determining time is short, the tanshinol content is used as a quality control index in the Naozhengning preparation, the product quality of the Naozhengning preparation can be effectively controlled, and the transfer rate of the salvianic acid A sodium can be appraised more scientifically. |
