| titleOfInvention | A method for rapid detection of matrine residues in tea leaves |
| abstract | The present invention relates to a method for rapidly detecting the residual amount of matrine in tea, comprising the following steps: 1) sample pretreatment: the sample is pulverized with a pulverizer and then passed through a 2.0mm sieve, mixed evenly and packed into a self-sealing bag, and sealed for use; 2) ) Extraction of samples: take samples, extract with ammonia water and acetonitrile; 3) Purification of samples: after passing the extract through FaPEx purification column, dilute and mix with ammonia-acetonitrile solution; 4) Preparation of matrix calibration solution: weigh out The negative tea samples of ginseng were prepared according to the above-mentioned steps to prepare a negative sample extract, which was used to prepare a quality standard solution of matrine; 5) using liquid chromatography-tandem mass spectrometry to measure the concentration of matrine in the sample solution; 6) according to The concentration of matrine in the sample solution is used to calculate the residual amount of matrine in the sample; the determination method of the invention is fast and simple, can realize the accurate determination of the content of matrine in tea leaves, and solves the detection method of the residual amount of matrine in tea leaves. The operation is complicated and lengthy. |
