Embodiment 1
[0076] Example 1 of the present invention: A method for determining the content of Verbasil glycosides in Zhenqi Fuzheng preparations was carried out according to the following steps:
[0077] (1) Chromatographic conditions and system suitability test: octadecylsilane-bonded silica gel is used as filler; acetonitrile: 0.2% formic acid aqueous solution=20:80 as mobile phase; detection wavelength is 260nm; flow rate is 1.0mL / min ; The column temperature is 35℃; the number of theoretical plates should not be less than 3000 according to the peak of the mullein isoflavone glycoside;
[0078] (2) Preparation of reference solution: accurately weigh out an appropriate amount of verbasil glycoside reference substance, add methanol to make a 0.1mg / mL solution, and set aside;
[0079] (3) Preparation of test solution: accurately weigh 2.0g of Zhenqi Fuzheng preparation or its contents, accurately add 100mL of 70%-75% ethanol, weigh it, extract it with ultrasound for 1h, make up the weight with ...
Embodiment 2
[0081] Example 2 of the present invention: A method for determining the content of Verbasil glycosides in Zhenqi Fuzheng preparations was performed according to the following steps:
[0082] (1) Chromatographic conditions and system suitability test: use octadecylsilane bonded silica as filler; use acetonitrile:0.05% glacial acetic acid=30:70 as mobile phase; detection wavelength is 260nm; flow rate is 0.8mL / min ; The column temperature is 35℃; the number of theoretical plates should not be less than 3000 based on the peak of mullein isoflavone glycoside;
[0083] (2) Preparation of reference solution: accurately weigh out an appropriate amount of verbasil glycoside reference substance, add methanol to make a 0.1mg / mL solution, and set aside;
[0084] (3) Preparation of test solution: accurately weigh 2.0 g of Zhenqi Fuzheng preparation or its contents, accurately add 100 mL of methanol, weigh it, and extract with ultrasound or reflux for 1 hour, make up the weight with methanol, fil...
