| titleOfInvention | Method for measuring content of alkaloid components in blood-nourishing brain-refreshing alcohol extract |
| abstract | The invention relates to a method for measuring the content of alkaloid components in an alcohol extract for nourishing blood and refreshing brain, which adopts a high performance liquid chromatography and comprises the following steps: step 1, preparing a reference substance solution; step 2, preparing a test solution; and 3, injecting the reference solution and the test solution into a chromatograph to obtain a chromatogram, and calculating the content of the alkaloid component according to the peak area. The invention adopts ultra-high performance liquid chromatography to measure the alkaloid components in the blood-nourishing brain-refreshing alcohol extract. The solid phase extraction technology is adopted to separate and purify the sample, so that the interference components can be effectively removed, and the alkaloid components can be effectively enriched. The method is efficient and rapid, has good stability and high sensitivity, and can realize effective separation of five alkaloid components within 7 minutes. Proved by methodology, the quality control method has good precision, reproducibility and stability, and can effectively measure the alkaloid components in the blood-nourishing brain-refreshing alcohol extract. |
