Embodiment 1
[0066] Example 1 of the present invention: the content determination method of salidroside, calycosin glucoside, privetin and formononetin in Zhenqi Fuzheng Granules:
[0067] (1) Chromatographic conditions and system adaptability test: Octadecylsilane silica gel as filler; acetonitrile (A)-water (B) as mobile phase, gradient elution: 0-10min, 95% (A) ~90%(A), 10~30min, 90%(A)~78%(A), 30~40min, 78%(A)~73%(A), 40~55min, 73%(A)~45 %(A); the column temperature is 35°C; the detection wavelength is 220nm; the flow rate is 0.8mL / min; the number of theoretical plates shall not be less than 3000 based on salidroside.
[0068] (2) Preparation of reference substance solution: take appropriate amount of reference substances of salidroside, acteosin glucoside, prigulin and formononetin, and add methanol to make the concentration containing salidroside 0.13mg / mL, acteosin, respectively. A solution of flavonoid glucoside 0.35mg / mL, privetin 0.2mg / mL, and formononetin 0.015mg / mL is availabl...
