Embodiment 1
[0045] In a 5L constant temperature bath, add 50g of the crude product of tanshinone IIA sodium sulfonate (produced by Shanghai First Biochemical Pharmaceutical Co., Ltd.), dissolve it with 3L of 80% (v / v) methanol solution at a temperature of 60°C, and stir until all dissolve. Add 25g of activated carbon (Shanghai Activated Carbon Factory Co., Ltd.), stir for 1 hour, and suction filter while it is hot. The filtrate is concentrated to 60% under reduced pressure (relative pressure -0.09MPa) at 35°C, and the concentrated solution is placed in a freezer at -3°C for refrigerated analysis. crystallized, frozen for 20 hours, suction filtered to dryness, and the filter cake was put into a vacuum oven at 30° C. to dry for 24 hours to obtain 47 g of pure tanshinone IIA sodium sulfonate, with a yield of 94%. After HPLC detection, the calculated content of the dry product was 98.9%; organic solvent residues detected by gas chromatography, methanol was 0.1%, and methylene chloride was not...
Embodiment 2
[0047] In a 5L constant temperature bath, add 50g of the crude product of tanshinone IIA sodium sulfonate (produced by Shanghai First Biochemical Pharmaceutical Co., Ltd.), dissolve it with 3L of 80% (v / v) methanol solution at a temperature of 60°C, and stir until all dissolve. Add 25g of diatomaceous earth, stir for 1.5 hours, and suction filter while it is hot. The filtrate is concentrated to 60% under reduced pressure (relative pressure-0.1MPa) at 30°C. Suction filtration to dryness, the filter cake was put into a vacuum drying oven at 30°C and dried for 24 hours to obtain 46 g of pure tanshinone IIA sodium sulfonate, with a yield of 92%. The calculated content of the dried product was 99.4% through HPLC detection; The solvent remained, methanol was 0.05%, and dichloromethane was not detected.
Embodiment 3
[0049] In a 5L constant temperature bath, add 50g of crude sodium tanshinone IIA sulfonate (produced by Shanghai First Biochemical Pharmaceutical Co., Ltd.), dissolve with 3.5L of 90% (v / v) methanol solution, the temperature is 55% ℃, stir until completely dissolved. Add 15g of activated carbon (Shanghai Activated Carbon Factory Co., Ltd.), stir for 1 hour, and suction filter while it is hot. The filtrate is concentrated to 45% under reduced pressure (relative pressure -0.09MPa) at 30°C, and the concentrate is placed in a freezer at 7°C for freezing and crystallization. , frozen for 20 hours, suction filtered until dry, and the filter cake was dried in a vacuum oven at 30°C for 20 hours to obtain 46 g of pure tanshinone IIA sodium sulfonate, with a yield of 92%. The calculated content of the dry product was 99.3% by HPLC detection. %; gas chromatography detection of organic solvent residues, methanol was 0.08%, dichloromethane was not detected.
