Embodiment 1
[0027] The preparation of the total flavonoids and total polysaccharides of embodiment 1 desmodium
[0028] (1) Take Desmodium, crush it, add 80% v / v ethanol 12 times the weight of Desmodium, reflux extraction twice, each time for 1.5h, filter, and use the dregs and alcohol extract for later use;
[0029] (2) Take the alcohol extract obtained in step (1), concentrate it to 0.5g raw medicinal materials / ml, apply NKA-9 macroporous adsorption resin, and use 3-4BV water (Molish reaction negative), 4BV10% ethanol, 4BV70% Ethanol, eluting, collecting 70% v / v ethanol eluate, recovering the solvent under reduced pressure, and drying to obtain the total flavonoids of Desmodium desmodium; wherein, the total content of quercetin and kaempferenin is 4.61%, and the content of flavonoids is calculated as rutin 51.39%, and the cream yield is 1.94%.
[0030] (3) Take the dregs obtained in step (1), add 10 times the amount of water to decoct twice, each time for 2 hours, combine the water ext...
