Embodiment 1
[0028] Embodiment 1: Compound 1 preparation
[0029] First, 2 kg of Dahongpao medicinal material was added, and 16 L (2 L was added for the first time) of 80% ethanol was heated and extracted at 80° C. for 3 times, each time for 1 hour. Then the extract was concentrated under reduced pressure (pressure 98Kpa) at a temperature of 50° C., and the concentrate was dispersed in 2 L of water to prepare a suspension. Add chloroform for extraction three times, 2 L each time, to obtain chloroform extract, which is concentrated under reduced pressure at 40° C. (pressure 98 Kpa), to obtain 91.3 g of chloroform extract.
[0030] Take 50 g of the chloroform extract and mix the sample with an equal amount of silica gel, separate by silica gel column chromatography (300-400 mesh), elute with petroleum ether: ethyl acetate (2:1-1:1), check with TLC, combine and wash The liquid was removed, concentrated, and the eluate was applied to a reversed-phase C18 column, methanol: water (50:50-70:30),...
