Embodiment 1
[0071] Example 1 Related substance inspection and content determination of Tanshinone IIA sodium sulfonate bulk drug
[0072] relative substance
[0073]Determined by high performance liquid chromatography (Chinese Pharmacopoeia 2000 edition two appendix V D), using octadecylsilane bonded silica gel as filler, methanol-water (volume ratio 70:30) (every 100mL water contains tetrabutyl hydroxide Ammonium (2mmol) was used as the mobile phase, the flow rate was 1mL / min, and the detection wavelength was 246nm. Get an appropriate amount of tanshinone I sulfonate sodium reference substance (self-made, confirmed by structure), accurately weighed, add mobile phase to make a solution containing 20 μg of tanshinone I sulfonate sodium in every 1 mL, and accurately measure the tanshinone I sulfonate sodium reference substance solution 10 μL was injected into the chromatograph, the chromatogram was recorded, and the peak area was calculated. Another take tanshinone IIA sodium sulfonate cr...

[0079] Example 2 Related substance inspection and content determination of tanshinone IIA sodium sulfonate bulk drug
[0080] relative substance
[0081] Determined by high performance liquid chromatography (Chinese Pharmacopoeia 2000 edition two appendix V D), with octadecylsilane bonded silica gel as filler, methanol-water (volume ratio 75:25) (every 100mL of water containing tetrabutyl hydroxide Ammonium (2mmol) was used as the mobile phase, the flow rate was 1mL / min, and the detection wavelength was 250nm. Take an appropriate amount of tanshinone I sulfonate reference substance (self-made, confirmed by structure) and tanshinone IIA reference substance, accurately weighed, add dichloromethane and methanol to dissolve, add mobile phase to make each 1mL containing tanshinone I sulfonate sodium 20 μg and Tanshinone IIA 20μg mixed reference substance solution, accurately measure 10μL of mixed reference substance solution and inject it into the chromatograph, record the chromat...
Embodiment 3
[0083] Example 3 Inspection and Content Determination of Related Substances of Tanshinone IIA Sodium Sulfonate Powder Injection
[0084] relative substance
[0085] Measured by high performance liquid chromatography (Chinese Pharmacopoeia 2000 edition two appendix V D), with octadecylsilane bonded silica gel as filler, with acetonitrile-water (volume ratio 50:50) (every 100mL water contains tetramethyl Ammonium bisulfate (0.2mmol) was the mobile phase, the flow rate was 2mL / min, and the detection wavelength was 246nm. Get an appropriate amount of tanshinone I sulfonate sodium reference substance (self-made, confirmed by structure), accurately weighed, add mobile phase to make a solution containing 20 μg of tanshinone I sulfonate sodium in every 1 mL, and accurately measure the tanshinone I sulfonate sodium reference substance solution 10 μL was injected into the chromatograph, the chromatogram was recorded, and the peak area was calculated. Take another tanshinone IIA sodium...
