Embodiment 1
[0066] This embodiment provides a method for constructing a characteristic map of the freeze-dried powder of Fructus Chickens, comprising the following steps,
[0067] (1) Preparation of reference substance solution: get stachydrine hydrochloride, add 70% ethanol to make every 1ml contain 0.2mg stachydrine hydrochloride reference substance solution;
[0068] Preparation of the test solution: Get 0.1g of the lyophilized powder of Azurite chinensis, grind it finely, accurately weigh it, put it in a conical flask, add 10ml of 70% ethanol aqueous solution precisely, seal it tightly, weigh it, and test it at a power of 500W, frequency Ultrasonic treatment at 40kHz for 30min, let cool, weigh again, make up the lost weight with 70% ethanol aqueous solution, shake well, filter through 0.22μm microporous membrane, take the filtrate, and obtain.
[0069] (2) Accurately draw 10 μ L of need testing solution and reference substance solution respectively and inject into high performance liq...
Embodiment 2
[0075] This embodiment provides a method for constructing a characteristic map of the freeze-dried powder of Fructus Chickens, comprising the following steps,
[0076] (1) Preparation of reference substance solution: get stachydrine hydrochloride, add 70% ethanol to make every 1ml contain 0.23mg stachydrine hydrochloride reference substance solution;
[0077] Preparation of the test solution: Get 0.1g of the lyophilized powder of Azurite chinensis, grind it finely, accurately weigh it, put it in a conical flask, add 10ml of 70% ethanol aqueous solution precisely, seal it tightly, weigh it, and test it at a power of 500W, frequency Ultrasonic treatment at 40kHz for 30min, let cool, weigh again, make up the lost weight with 70% ethanol aqueous solution, shake well, filter through 0.22μm microporous membrane, take the filtrate, and obtain.
