| titleOfInvention | Method for measuring polyphenol content in rhizoma polygonati based on spectrometry |
| abstract | The invention discloses a method for determining the content of polyphenol in polygonatum sibiricum based on a spectrum method, and relates to the technical field of chemical detection. The method for measuring the polyphenol content in rhizoma polygonati based on the spectrum method comprises the following steps: the method comprises the steps of preparing experimental materials, selecting fresh rhizoma polygonati tubers, cleaning, slicing and drying, crushing the dried rhizoma polygonati into powder by using a crusher, degreasing the rhizoma polygonati powder for 3 hours by using petroleum ether, drying, sieving by using a 40-mesh sieve, placing in a refrigerator in a dark place for freezing and storing, fully grinding by using potassium bromide as a diluent, pressing into uniform sheets, and then measuring the polyphenol content in a rhizoma polygonati sample to be measured by using an infrared spectroscopy. The method for determining the content of the polyphenol in the polygonatum sibiricum based on the infrared spectroscopy is simple to operate, does not need to add complex chemicals, is rapid and accurate, has high precision and good repeatability, and is an ideal method for determining the content of the polyphenol in the polygonatum sibiricum. |
