Embodiment 1
[0047] Embodiment 1 of the present invention: the assay method of Radix Astragali granule fingerprint comprises the following steps:
[0048] (1) Preparation of the test solution: crush Astragalus granules, pass through a 60-mesh sieve, accurately weigh 1.0g of the powder, add 10mL of 10% methanol solution to dissolve, ultrasonically extract for 5min, then cool, make up for the lost weight, shake well, filter After passing, take the continued filtrate and pass through a 0.45 μm microporous membrane to obtain the test solution;
[0049] (2) Preparation of the reference substance solution: take the reference substance of acteocoside, formononetin, acteosin, and formononetin, which were dried under reduced pressure to constant weight, and add methanol respectively to make each 1mL containing 0.562mg of acteosin Glycoside, 0.254mg formononetin, 0.357mg calycosin, 0.274mg formononetin reference substance solution (stored in a refrigerator at 4°C for later use);
[0050] (3) Determ...
