AI Technical Summary

Problems solved by technology

At room temperature, Tanshinone II A The solubility of sodium sulfonate in general organic solvents (such as methanol, ethanol, acetone, etc.) and polar solvents (such as water) is very small, even if the temperature is raised to reflux temperature such as 70-80 ° C, the solubility increases slightly, but it is carried out with a single solvent. The recrystallization effect is not obvious, and the amount of solvent used is large. After the refined sample is analyzed by HPLC, the content can only be about 93-97%, and the purity cannot meet the requirements of injections

Embodiment 1

[0031] In a 100ml reaction bottle, add Tanshinone II A Sodium sulfonate crude product 1.0g (commercially available, HPLC method content 93.6%, m.p. = 234 ° C ~ 235 ° C, see attached Figure 1 ,), suspended in a mixed solvent consisting of 7ml of deionized water, 1ml of acetone and 6ml of absolute ethanol, fully stirred, the temperature of the water bath was raised to 50°C to 55°C until all the samples were dissolved, hot filtered, the filter residue was discarded, and the filtrate was slowly cooled to 5 ℃, crystallize for 4 hours, filter, and put the filter cake in a vacuum drying oven A Sodium sulfonate pure product 0.8g, m.p. = 239 ℃ ~ 240 ℃ (measured by X-4 micro melting point apparatus, Shanghai Precision Scientific Instrument Co., Ltd.), the yield is 80.0%, and the content is 100.1% based on dry product.

Embodiment 2

[0033] In a 250ml reaction bottle, add Tanshinone II A Sodium sulfonate crude product 16.0g (same as Example 1), is suspended in the mixed solvent that 80ml deionized water and 80ml acetone form, fully stirs, and water bath is warmed up to 50 ℃~55 ℃ to sample all dissolvings, heat filtration, discard filter residue, Slowly lower the temperature of the filtrate to 0°C, crystallize for 4 hours, filter, and place the filter cake in a vacuum drying oven at A 12.9g of pure sodium sulfonate, m.p.=238°C-240°C, yield 80.6%, content of dry product is 99.9%.

Embodiment 3

[0035] In a 250ml reaction bottle, add Tanshinone II A Sodium sulfonate crude product 16.0g (same as Example 1), is suspended in the mixed solvent that 80ml deionized water and 80ml acetone form, fully stirs, and water bath is warmed up to 40 ℃~45 ℃ to all dissolving of sample, heat filtration, discard filter residue, The filtrate was slowly cooled to 30°C, crystallized for 4 hours, filtered, and the filter cake was fully washed with about 10ml of iced deionized water, drained and placed in a stainless steel shallow tray for freeze-drying (-40°C-35°C, 30- 36h), namely Tanshinone II A Sodium sulfonate pure product 12.7g, m.p.=239 ℃~240 ℃ (same as embodiment 1), yield 63.4%, content is 101.3% with dry product.

Abstract

The invention relates to a refining method of sodium tanshinone IIA sulfonate. The method comprises the following procedures, a) adding a crude sodium tanshinone IIA sulfonate to be purified into a mixture solution of an organic solvent and water, heating to 40 to 60 DEG C, agitating to dissolve and filtering to remove insoluble particles; b) slowly cooling the filtrate to the temperature of 0 to 30 DEG C and crystallizing and filtering; c) obtaining the sodium tanshinone IIA sulfonate with high purity after the decompression drying. The contents of the obtained sodium tanshinone IIA sulfonate can reach 99.5 percent and the quality can meet the purity requirement of a raw medicine for injection. The method of the invention is simple and is easy to operate with low refining cost, and is applicable for the industrialized production.

Description
