Embodiment Construction

[0069] A flavonoid compound of the present invention is obtained by extracting, separating and purifying from Fructus Grucoides by the following method:

[0070]Take 10kg of scorpion seeds, crush them to 20-40 mesh, add 10 times the volume of 95% ethanol to reflux and extract 3 times, each time for 60min, combine the extracts, filter, and concentrate under reduced pressure to obtain 1.57kg of extract, which is mixed with distilled water Add an equal volume of petroleum ether (60°C-90°C) to the separatory funnel to extract, shake fully, and collect the aqueous phase solution after the mixed liquid is separated. After repeated operations for 5 times, add an equal volume of acetic acid to the aqueous phase solution Ethyl ester extraction, fully oscillated and mixed, after the mixed solution was clarified and stratified, collected the aqueous phase solution, after repeated operations 5 times, the aqueous phase solution was extracted by adding an equal volume of n-butanol, fully osc...
