| titleOfInvention | Method for simultaneously determining baicalin, emodin, physcion and chrysophanol in Qiqing toxin-vanquishing particles |
| abstract | The invention discloses a method for simultaneously determining baicalin, emodin, physcion and chrysophanol in Qiqing toxin-vanquishing particles, which comprises the following steps: preparing a plurality of groups of standard working solutions, testing the working solutions by an ultra-high performance liquid chromatograph, calculating the obtained standard curves to obtain linear regression equations of baicalin, emodin, physcion and chrysophanol, preparing a test solution by using Qiqing toxin-vanquishing particles, testing the test solution on a computer, respectively recording corresponding peak areas, substituting the peak areas into the obtained respective linear regression equations, and calculating the contents of the baicalin, the emodin, the physcion and the chrysophanol. The invention has the beneficial effects that: the detection limit and the quantification limit of the method are reduced by using the UPLC-PDA to detect under specific chromatographic conditions; the method is economical, rapid, sensitive and good in reproducibility, saves time and mobile phase compared with the common liquid chromatography time, reduces the use of laboratory reagents and the discharge of waste liquid, and accords with the principles of energy conservation and emission reduction. |
