Embodiment 1

[0064] Extraction of Tanshinone Compounds

[0065] Weigh 3 kg of crushed salvia miltiorrhiza (origin: Yunnan, Ganzi, Aba area), add 14 L of ethanol with a mass fraction of 90%, and extract in a 40°C water bath for 2 hours. Use 350-mesh filter cloth and filter paper to remove medicinal material residue and soil, concentrate the filtrate to 1.4L, let stand at 4°C for 24 hours, filter the filtrate after standing, and dry the obtained solid under vacuum at 40°C to obtain red tanshinone compound Solid powder 65.0g.

[0067] Sulfonation and post-treatment of tanshinone compounds

[0068] Take 60g of tanshinone compounds in Example 1, add 140mL of glacial acetic acid and 360mL of acetic anhydride, stir and cool the suspension to 0°C. While stirring, add 60mL of 98% concentrated sulfuric acid to 60mL of glacial acetic acid to prepare a mixed acid solution and let it stand to cool to room temperature. Add the mixed acid solution dropwise, maintain the reaction temperature at 10°C, and continue the heat preservation reaction for 90 minutes. Prepare dilution solution by 300mL petroleum ether + 600mL dichloromethane + 650mL purified water, stir and cool to 4°C. In the state of stirring, slowly add the above reaction liquid into the dilution liquid, and strengthen the cooling effect to ensure that the temperature of the system is lower than 25°C. Add 700g of sodium chloride to 2L of purified water, stir well to prepare saturated saline. The diluted reaction liquid was added into saturated brine...

Abstract

The invention discloses a method for preparing przewaquinone sodium sulfonate. The preparation method comprises the following steps: separating tanshinone sulfonated liquid by adopting high performance liquid chromatography, wherein the conditions of the high performance liquid chromatography are as follows: the mobile phase A is 0.1% triethylamine-water, the mobile phase B is 0.1% triethylamine-methanol, or the mobile phase A is 0.1% diethylamine-water, the mobile phase B is 0.1% diethylamine-methanol, or the mobile phase A is 0.1% ethylamine-water, the mobile phase B is 0.1% ethylamine-methanol, or the mobile phase A is water, the mobile phase B is methanol, the percent is the volume percent of the component in the mobile phase, and the detection wavelength is 271nm. The preparation method disclosed by the invention is strong in preparation ability, large in preparation quantity, short in cycle, and high in efficiency, an organic solvent is reduced, the process operation continuity is strong, and mass control and production are easily carried out.

Description

technical field [0001] The invention relates to the field of medicaments, in particular to a preparation method of salvia miltiorrhiza sodium sulfonate. Background technique [0002] Salvia miltiorrhiza, also known as blood ginseng, red root, red root, blood root, is the rhizome of Labiatae (Salvia miltiorrhza), and its medicinal use was first recorded in "Shen Nong's Herbal Classic". Traditional Chinese medicine believes that its taste is bitter and slightly cold, and has the effects of promoting blood circulation and dysmenorrhea, dispelling blood stasis and relieving pain, clearing heart and eliminating troubles, cooling blood and eliminating carbuncle, and is suitable for treating irregular menstruation, dysmenorrhea, amenorrhea, metrorrhagia, leukorrhea, coronary heart disease, arterial Atherosclerosis, hyperlipidemia, angina pectoris, bruises and congestion, insomnia, neurasthenia, hepatitis B and other diseases are commonly used by patients with blood stasis and heat ...
