Examples
Embodiment 1
[0152] Take Yixin Fumai Granules numbered as Test 1, and measure the contents of salvianolic acid B and schisandrin A.
[0153] Step 1: Preparation of Schizandrin A Reference Substance Solution
[0154] Take an appropriate amount of schisandrin A reference substance, accurately weigh it, add 70% methanol to make a solution containing 0.036 mg of schisandrin A per 1 ml, and obtain it.
[0155] Step 2: Preparation of Yixin Fumai Granules Test Solution
[0156] Take an appropriate amount of Yixinfumai granule, grind it finely, take about 1.0g, accurately weigh it, add 10ml of 70% methanol to ultrasonically dissolve it for 30 minutes, take it out, place it at room temperature, make up the lost weight with 70% methanol, shake well, centrifuge, and pass through 0.45 Filter through a microporous membrane of μm, and take the filtrate.
[0157] Step 3: Inject the Schizandrin A reference substance solution and the test solution into the high-performance liquid chromatograph respective...
Embodiment 2
[0161] Take Yixin Fumai Granules numbered as Experiment 2, and measure the contents of salvianolic acid B and schisandrin A.
[0162] Step 1: Preparation of Schizandrin A Reference Substance Solution
[0163] Take an appropriate amount of schisandrin A reference substance, accurately weigh it, add 70% methanol to make a solution containing 0.030 mg of schisandrin A per 1 ml, and obtain the product.
[0164] Step 2: Preparation of Yixin Fumai Granules Test Solution
[0165] Take an appropriate amount of Yixinfumai granules, grind them finely, take about 1.0g, weigh them accurately, add 5ml of 70% methanol to dissolve them by ultrasonication for 20 minutes, take them out, place them at room temperature, make up the lost weight with 70% methanol, shake well, centrifuge, and pass through 0.45 Filter through a microporous membrane of μm, and take the filtrate.
[0166] Step 3: Inject the Schisandrin A reference substance solution and the test solution into the high-performance li...
Embodiment 3
[0170] Take Yixin Fumai Granules numbered as Test 3, and measure the contents of salvianolic acid B and schisandrin A.
[0171] Step 1: Preparation of Schizandrin A Reference Substance Solution
[0172] Take an appropriate amount of the reference substance of schisandrin A, accurately weigh it, add 70% methanol to make a solution containing 0.040 mg of schisandrin A per 1 ml, and obtain it.
[0173] Step 2: Preparation of the test solution
[0174] Take an appropriate amount of Yixinfumai granules, grind them finely, take about 1.0g, weigh them accurately, add 20ml of 70% methanol to ultrasonically dissolve them for 40 minutes, take them out, place them at room temperature, make up the lost weight with 70% methanol, shake well, centrifuge, pass through 0.45 Filter through a microporous membrane of μm, and take the filtrate.
[0175] Step 3: Inject the Schizandrin A reference substance solution and the test solution into the high-performance liquid chromatograph respectively,...
