preparation example 1

[0019] Weigh 26.5 grams of mangiferin and 23.5 grams of berberine hydrochloride, put them in a container, add 6000ml of 35% ethanol aqueous solution, stir while heating, and dissolve completely after slightly heating up; reclaim ethanol under reduced pressure, further concentrate to 2000ml, filter , to obtain a mangiferin-berberine composition solution with a concentration of 2.5%. This solution is very stable.

preparation example 2

[0021] Weigh 28 grams of mangiferin and 22 grams of berberine, put them in a container, add 3000ml of 25% ethanol aqueous solution, stir while heating, until they are completely dissolved; recover the ethanol under reduced pressure, further concentrate to 500ml, and filter to obtain mango Glycoside-berberine composition solution, concentration 10%. After preparation, it should be used in the next process within 3 hours to avoid crystallization.

preparation example 3

[0023] Weigh 26.2 grams of mangiferin and 23.8 grams of berberine sulfate, put them in a container, add 5000ml of 20% ethanol aqueous solution, stir while heating, until they are completely dissolved; recover ethanol under reduced pressure, further concentrate to 1250ml, and filter to obtain Mangiferin-berberine composition solution, concentration 4%. This solution is very stable.
