| titleOfInvention | Method for determining fingerprint spectrum of compound rhizoma et radix baphicacanthis cusiae granules |
| abstract | The invention provides a method for measuring a fingerprint spectrum of compound south isatis root granules. The construction method of the fingerprint comprises the following steps: preparing a test solution: grinding compound rhizoma et radix Baphicacanthis Cusiae granules, extracting with organic solvent, and filtering; preparation of a reference solution: weighing aesculetin and caffeic acid, and dissolving in an organic solvent; and (3) high performance liquid chromatography detection: sucking the test solution and the reference solution, injecting into a high performance liquid chromatograph, and measuring by high performance liquid chromatography to obtain compound rhizoma Et radix Baphicacanthis Cusiae granule fingerprint. The fingerprint spectrum has large information amount and rich spectrum peak information, comprises 9 common peaks, and the common peaks belong to different medicinal materials of compound rhizoma et radix baphicacanthis cusiae particles respectively. In addition, the invention keeps the base line stable under the condition of more peaks, and has high precision, stability and good reproducibility. |
