Embodiment 1
[0048] Prepare castor, pokeweed, licorice, and pine cones to prepare the medicament for treating AIDS and tumors according to the following process steps:
[0049] (1) Extraction process of ricin: first peel off the outer hard shell of castor, grind the white kernels into a paste, and remove the castor oil
[0050] (1) Add 3 times the amount of ethanol below 12°C and soak for 4 hours, then centrifuge, take the precipitate, knead it with water, and freeze-dry the aqueous solution to obtain the crude product. , filter out the precipitate, add a small amount of ethanol to the mother liquor until it is slightly turbid, put it in the refrigerator to precipitate crystals, and recrystallize if necessary;
[0051] (2) Alcohol fractional precipitation method: add 3 times the amount of ethanol to castor bean paste, precipitate out, and remove it by centrifugation; then add 1 times the amount of ethanol to the mother liquor, and centrifuge to collect this part of the precipitate, but it ...
Embodiment 2
[0072] Other steps are the same, the difference is:
[0073] The second step in the aforementioned ricin extraction process is the salt fractionation precipitation method: add ammonium sulfate to the saturation of 40% to the original paste, so the color of the precipitate is darker, and it is removed by centrifugation; add ammonium sulfate to the saturation of 50% in the mother liquor , Collect this part of the precipitate, but it is not pure; add ammonium sulfate to the mother liquor to 75% saturation, and the resulting protein precipitate is relatively pure.
[0074] The extraction of crude glycyrrhizic acid in the aforementioned glycyrrhizic acid extraction process for injection is extracted with licorice extract, and the method is as follows:
[0075] 3 kg of licorice extract, heated and dissolved in 36 liters of water, cooled to room temperature, and 145 ml of concentrated sulfuric acid was added dropwise while stirring; after the addition was completed, it was left to st...
