Embodiment 1
[0023] Embodiment 1 The fingerprint detection of Rhizoma Chuanxiong aerial part of the present invention
[0024] 1) Preparation of the test solution: Take 2.0 g of the sample powder of the aboveground part of Rhizoma Chuanxiong (passed through a No. 6 sieve), accurately weigh it, put it in a 50 mL conical flask with a stopper, add 10 mL of methanol accurately, weigh it, and ultrasonically treat it for 30 minutes , let it cool, make up for the weight loss, shake well, pass through a 0.22 μm microporous membrane, and take the subsequent filtrate to obtain;
[0025] 2) Preparation of reference substance solution
[0026] Take 10mg of ligustilide reference substance, weigh it accurately, add methanol to a 10mL volumetric flask, dissolve to the mark, and shake well to obtain a stock solution of ligustilide reference substance with a concentration of 1.0780mg / mL. Precisely measure 1.0mL of the stock solution, put it in a 5mL volumetric flask, add methanol to dilute to the mark, sh...
