| titleOfInvention | Determination method of total flavonoids in Wendan Decoction |
| abstract | The invention provides a method for determining the content of total flavonoids in Wendan Decoction, which belongs to the technical field of drug detection. The method for determining is as follows: firstly, taking naringin to prepare a reference solution with a concentration of C pairs , and then determining by ultraviolet-visible spectrophotometry Absorbance, obtain the reference substance absorbance A pair ; then take the Wendan decoction with a weight of m temperature and add it to 69～71wt% ethanol to dissolve, extract by ultrasonic, filter to obtain the test solution with a volume of V, and then pass the ultraviolet- Measure the absorbance by visible spectrophotometry, get the test solution absorbance A, and finally calculate the total flavonoid content in the Wendan Decoction. In this study, the content of total flavonoids in Wendan Decoction was determined by direct determination method, which was simple and repeatable, and the optimal extraction process of total flavonoids from Wendan Decoction was determined. The research on major components can reflect the benchmark samples of Wendan Decoction from an overall perspective, and provide a basis for subsequent research. |
