| titleOfInvention | LC-MS method for detection of kaempferol in Luo Han Guo tea |
| abstract | The invention provides a method for detecting kaempferol in Luo Han Guo tea by liquid-mass series, aiming to provide a method for detecting kaempferol in Luo Han Guo tea by liquid-mass series with high sensitivity, qualitative and quantitative accuracy; the method is: 1) taking This product, accurately weighed, finely ground, ultrasonically treated, centrifuged to remove the lower precipitate, and dried; 2) In a microwave reactor, add chlorinated 1-alkyl-3-methylimidazole and methanol, and treat at 60°C for 10 minutes Obtain the extract; 3) Concentrate the extract to obtain a concentrate, add macroporous resin to the concentrate, mix and stir evenly, apply AB-8 resin after drying, wash with water until colorless, then rinse with ethanol solution, collect and wash Deliquification, washing, concentration and drying to obtain a dry powder; 4) Weigh 0.5 g of the dry powder in step 3), add 5 ml of 10% phosphoric acid solution, heat and reflux in a water bath for 30 minutes, let cool, quantitatively transfer to a 25 ml measuring bottle, and use methanol Dilute to the scale, filter the membrane, and take the filtrate for detection; it belongs to the technical field of chemical detection. |
