Embodiment 1
[0079] Take the seabuckthorn medicinal material, crush it, add ethyl acetate and 70% ethanol with a volume ratio of 1:2, heat and extract twice, the first time for 1 hour, and the second time for 1 hour, the filtrates are combined to obtain the extract I, and the dregs are added 70% ethanol, heated and refluxed for 2 times, 0.5 hours for the first time, 0.5 hours for the second time, the filtrates were combined to obtain the extract II, the combined extracts I and II were concentrated into extracts, and the extracts were dissolved with 50% ethanol. The macroporous resin AB-8 is used to separate it, first eluting with water to obtain eluent I; then eluting with 50% ethanol, and then eluting with 90% ethanol, and the elution flow rate is 1BV / h to obtain eluent I Liquid II was recovered, concentrated under reduced pressure, and dried to obtain the total flavonoids extract of Hippophae rhamnoides. After testing, the purity of total flavonoids from seabuckthorn can reach 24.19%.
