Embodiment 1
[0064] Get andrographolide, add 5.5 times the amount of acetic anhydride (62%) and glacial acetic acid (38%) to dissolve, and under stirring, slowly add 4.5 times the amount of sulfuric acid at a rate of 1.6ml per minute for 1g andrographolide (52%) and glacial acetic acid (48%), mix evenly, adjust the temperature of the reactor at 16° C., and place it for 90 minutes for sulfonation. Add an equal amount of purified water, stir well, adjust the pH to about 7.0 with 33% NaOH, add 95% ethanol to make the alcohol content reach more than 82%, recover ethanol under reduced pressure, and separate the aqueous solution through macroporous adsorption resin and ODS column chromatography. Gradient elution with water: ethanol, the proportion of water is 80-20%, the proportion of ethanol is 20-80%, the eluate is collected in sections, the same components are combined, and crystallized to obtain 17-hydrogen-9-dehydroandrographis paniculata Sodium lactone-3-sulfate, its sodium salt formula C ...
Embodiment 2
[0072] Get andrographolide, add 5.3 times the amount of acetic anhydride (62%) and glacial acetic acid (38%) to dissolve, and under stirring, slowly add 4.3 times the amount in equal proportions at a rate of 2.2ml per minute for 1g of andrographolide Sulfuric acid glacial acetic acid, mix well, adjust the temperature of the reaction kettle at 15°C, place it for 90 minutes for sulfonation, add an equal amount of purified water, then pour it into saturated sodium chloride solution, and then go through macroporous adsorption resin and ODS column chromatography Separation, gradient elution with water: ethanol, the proportion of water is 80-20%, the proportion of ethanol is 20-80%, the eluate is collected in sections, the same components are combined, and crystallized to obtain 17-hydrogen-9-de Sodium hydroandrographolide-3,19-disulfate, its sodium salt Molecular formula: C 20 h 28 Na 2 o 11 S 2 , Molecular weight: 554.
