Embodiment 1
[0054] The assay method of the content of actascoside in the nude flower purple pearl preparation adopts the high performance liquid chromatography to measure the content of the verbascoside in the nude flower purple pearl preparation test solution.
[0055] Chromatographic conditions and system suitability Octadecylsilane-bonded silica gel was used as filler, acetonitrile-0.1% acetic acid solution (16:84) was used as mobile phase, the detection wavelength was 332nm, and the number of theoretical plates should not be less than 4000 based on the peak of verbascoside.
[0056] Preparation of reference solution Take an appropriate amount of verbascoside reference substance, weigh it, add 50% methanol to make a solution containing 40mg per 1ml, and get it.
[0057] Preparation of the test solution Take 2 bags of Nudehuazizhu granules, grind them finely, take 0.7g, weigh them, put them in a 50ml stoppered Erlenmeyer flask, add 25ml of 50% methanol, weigh them, and treat ...
