Embodiment 1
[0019] An effective part of the umbrella, which is selected from one or any combination of the petroleum ether part, the ethyl acetate part or the n-butanol part of the ethanol extract of the umbrella; the specific extraction method is: the whole herb of the umbrella Dry in the shade and pulverize, take 1000 g of dried wind-seeking umbrella powder, soak it 3 times at room temperature with methanol aqueous solution with a volume fraction of 70% (the amount of methanol aqueous solution added is 3-5 times the weight of the wind-chasing umbrella powder), 3 times each time day, combined the obtained extracts three times and concentrated them into extracts; the extracts were dispersed in 1000ml distilled water, and then extracted with solvent petroleum ether (3000ml), ethyl acetate (3000ml) and n-butanol (3000ml) successively, each extraction Three times; after evaporating the solvent, the solid petroleum ether part (LPFPE), ethyl acetate part (LPFEA) and n-butanol part (LPFBU) were ...
Embodiment 2
[0022] Replace the methanol aqueous solution with volume fraction 70% with the ethanol aqueous solution of volume fraction 70%, other is with embodiment 1, obtain petroleum ether part (LPFPE), ethyl acetate part (LPFEA) and n-butanol part (LPFBU), extraction rate is respectively 1.5%, 5.8% and 2.2%.
[0023] Effect test
[0024] The petroleum ether part (LPFPE), the ethyl acetate part (LPFEA) and the n-butanol part (LPFBU) that the embodiment 1 selects 70% methanol aqueous solution and the embodiment 2 selects 70% ethanol aqueous alcohol extraction to obtain respectively below carry out the reduction Results of blood sugar test.
