Embodiment 1
[0044] Embodiment 1: the preparation of compound 1
[0045] Take 4.0Kg of the rhizome of Actaea asiatica Hara, and extract it three times with 20L of 70% ethanol under reflux, each time for three hours; after combining the three extracts, recover the solvent to obtain the extract. Dissolve the extract in 1L of water, extract with 1L of petroleum ether, 4L of ethyl acetate, and 4L of n-butanol in sequence to obtain 300 g of ethyl acetate extract. The ethyl acetate extract was subjected to low-pressure column chromatography on silica gel (200-300 mesh), and eluted with petroleum ether-acetone-methanol system gradient (1:0:0-9:1:0-8:2:0.2-7: 2.5:0.5-6:3:1-4:4:2), 5000ml each, collected and combined into 5 fractions, of which the first fraction (102g) was subjected to silica gel (200-300 mesh) low-pressure column chromatography again, Gradient elution with chloroform-methanol system (10:0-9:1-8:2-7:3-6:4-5:5), 5000ml each, collected 9 fractions in total. Among them, the seventh ...
