Embodiment 1
[0126] Embodiment 1, the fingerprint chromatogram determination of Kunling pill
[0127] Take the Kunling pill film-coated pill with batch number 20121102
[0128] Step 1, preparation of test solution
[0129] Take an appropriate amount of Kunling film-coated pills, grind them into fine powder, accurately weigh 0.5g into a 10ml volumetric flask, add an appropriate amount of 50% methanol, ultrasonically treat for 30min, cool to room temperature, set the volume to the mark, shake well, and pass through a micrometer of 0.45μm. Porous filter membrane, take the filtrate to obtain. Step 2, establishment of fingerprint
[0130] Using high performance liquid chromatography, the chromatographic conditions are as follows: the column stationary phase uses octadecylsilane bonded silica gel as the filler, Agilent ZORBAX (4.6*250mm, 5um); the mobile phase is gradient elution of acetonitrile-1% formic acid aqueous solution; The flow rate is 1.0ml / min; the column temperature is 30°C; the i...
Embodiment 2
[0134] Embodiment 2, the fingerprint chromatogram determination of Kunling pill
[0135] Take the Kunling pill film-coated pill with batch number 20121002

Embodiment 3
[0143] Embodiment 3, the fingerprint chromatogram determination of Kunling pill
[0144] Take the Kunling Wan sugar-coated pill with batch number 20120901
[0145] Step 1, preparation of test solution
[0146] Take an appropriate amount of Kunling Wan sugar-coated pills, remove the sugar coating (direct beating method), grind into a fine powder, accurately weigh 0.6g into a 10ml volumetric flask, add an appropriate amount of 60% methanol, ultrasonicate for 35min, cool to room temperature, and set the volume to the mark , Shake well, pass through a 0.45μm microporous membrane, and take the subsequent filtrate.
[0147] Step 2, establishment of fingerprint
[0148] Using high performance liquid chromatography, the chromatographic conditions are as follows: the stationary phase of the chromatographic column is filled with octadecylsilane bonded silica gel, Agilent ZORBAX (4.6*250mm, 5μm); the mobile phase is gradient elution of acetonitrile-1% formic acid aqueous solution; The...
