Embodiment 1
[0034] Example 1 The preparation steps of Zizhucao injection with astringent and hemostatic effects are as follows:
[0035] (1) Take the coarse powder of Zizhucao, extract it twice with water, boil for 1 hour each time, combine the two filtrates, concentrate to a thick paste, add ethanol, stir well, wash, separate on the distribution funnel, discard the ethanol Mother liquor, precipitation, and drying below 60°C to obtain dry powder of crude water extract;
[0036] (2) Take the crude dry powder obtained in step (1), dissolve it with a small amount of water for injection, add lead acetate, stir well, put it in the refrigerator overnight, separate and precipitate to obtain a light yellow solution, add 50% sulfuric acid dropwise to adjust pH 1 to remove lead, filter To obtain a light yellow solution, add 2N sodium carbonate dropwise to bring the pH to 6.5, add 5 times the amount of 65% ethanol to precipitate out, discard the mother liquor, and dry below 60°C to obtain a white ...
