Embodiment 1
[0109] This example is: using the method of the present invention to treat 10 batches of Xanthium rhinitis dripping pills (batch numbers: 041201, 041202, 041203, 041204, 041205, 041206, 041207, 041208, 041209, 041210, all by Sichuan Hebang Sunshine Pharmaceutical Co., Ltd. Provided by the company) to determine the content of baicalin, the specific method is as follows:
[0110] Chromatographic conditions and system suitability test: use octadecylsilane bonded silica gel as filler; methanol-water-phosphoric acid (47:53:0.2, volume ratio) solution as mobile phase, flow rate 1ml / min; detection wavelength is 280nm ; Column temperature: 40℃. The number of theoretical plates is not less than 2500 based on the peak of baicalin.
[0111] Preparation of reference solution: accurately weigh an appropriate amount of baicalin reference substance, add 50% methanol to make a solution containing about 45μg of baicalin per 1ml, and get it.
[0112] Preparation of test solution: Take 0.4-0.6g of Xa...
