| titleOfInvention | A kind of safflower dyeing identification method based on nylon membrane microextraction |
| abstract | The invention discloses a safflower dyeing identification method based on nylon membrane micro-extraction, which belongs to the field of quality detection of traditional Chinese medicines. The identification method includes: (1) soaking the safflower sample to be tested in an ethanol solution, standing for extraction, and collecting the extract; (2) using a nylon membrane as the extraction membrane, filtering the extract through a nylon membrane filter to make it Adsorb the dye substances in the extract; (3) filter the alkaline aqueous solution through the nylon membrane filter head to elute the dye substances adsorbed on the nylon membrane to obtain an eluent, and add an acid solution of the same concentration to the eluent to adjust the pH, Prepare the liquid to be tested; (4) observe whether the color of the liquid to be tested is colorless and transparent, if so, judge that the safflower sample to be tested is not dyed, and if it shows color, judge that the safflower sample to be tested is dyed. In the invention, the nylon membrane can be used to separate the dyeing agent from the safflower ethanol extraction solution, and whether the safflower is dyed can be directly judged according to the color of the dye extraction solution. The method is simple and practical, and is suitable for rapid on-site detection. |
