Embodiment 1
[0037] This example discloses the preparation method of isoandrographolide and a composition containing isoandrographolide-19-sulfate, andrographolide sulfonate E, andrographolide, and andrographolide
[0038] (1) Preparation of total sulfonated andrographolide (refer to Chinese patent, patent authorization number CN1162420C):
[0039] Take 1000mL of absolute ethanol and place it in a reactor, slowly add 1000mL of concentrated sulfuric acid dropwise, stir well, add 1000g of andrographolide, stir well, and place it at room temperature for 72h. Add 1000mL of ethanol in a water bath, stir well, adjust the pH to 7.0, add ethanol until the alcohol content reaches 80%, let it stand for 24 hours, add a small amount of activated carbon, filter, recover ethanol from the filtrate, condense into a thick paste, and vacuum dry to obtain Andrographis paniculata Total sulfonates of lactones.
[0040] (2) The total sulfonates of andrographolide are separated by column chromatography to prepa...
Embodiment 2
[0066] Isoandrographolide-19-sulfate was prepared according to the method in Example 1, weighed 1g, dissolved in about 800mL of glucose isotonic solution, added 0.1% activated carbon and stirred for 10 minutes, filtered, added glucose isotonic solution to 1000mL, filtered , use 10% sodium hydroxide solution to adjust the pH value to 4.5-6.5, potting (injection solution with large capacity, specifications are 50mL / bottle, 100mL / bottle, 250mL / bottle, 500mL / bottle), sterilized at 100°C for 30 minutes , after the clarity inspection, the package is ready.
Embodiment 3
[0068] The composition is prepared according to Example 1. Weigh 25g of the composition, add 600mL of water for injection, stir to dissolve, add 25g of mannitol, stir to dissolve, add water for injection to 1000mL, mix well, and filter with a 0.22μm microporous membrane to obtain The solution was divided into 7mL vials, 2mL per vial, capped, put into a lyophilizer, and lyophilized according to the designed lyophilization curve to obtain a composition lyophilized powder injection (50 mg each).
