Embodiment 1

[0239] Embodiment 1, the preparation method of patensin extract

[0240] (1) Preparation of Patratenin Extract

[0241] 50 kilograms of dry rhizomes of Palladium palatinea are crushed, moistened with methanol, put into a percolation barrel, and percolated with methanol. Concentrate under reduced pressure at 50°C, add hot water at about 50°C, and suspend. Extract with petroleum ether (60-90). A petroleum ether layer and an aqueous layer were obtained. The petroleum ether layer was concentrated to obtain a partial extract of petroleum ether. 200ml of the water layer was extracted with ethyl acetate and n-butanol in sequence, and recovered under reduced pressure to obtain the ethyl acetate part and the n-butanol part.

[0242] Take 250g of ethyl acetate extract, dissolve it with chloroform-methanol 10:1, mix with 500g of silica gel (100-200 mesh), and evaporate to dryness at 60°C. Pack a silica gel column, and the silica gel used for packing the column is 2000g. Elute with ...
