[0020] The natural product Jatamanvaltrate P (abbreviated as JP) preparation method: 7kg of spider vetch root and rhizome, crushed into coarse powder, cold-soaked with 95% ethanol for 48h, extracted by percolation, suspended in water, extracted 3 times with equal volume of dichloromethane , until the color of the extract is lighter. About 190 g of the dichloromethane extract was taken and separated by silica gel column chromatography, and eluted with petroleum ether-ethyl acetate (40:1-0:1) gradient to obtain a total of 11 fractions of Fr1-11. Take about 5 g of Fr7, and carry out reverse-phase medium-pressure column chromatography separation, use 40-60 micron octadecyl bonded phase silica gel as filler, and elute isocraticly with 60, 70, 75, 80, and 90% methanol respectively , 2000mL / gradient, 100mL / bottle, collected part of fractions eluted with 90% methanol, and recovered the solvent under reduced pressure to obtain about 106.1 mg of light yellow oily substance. Take about ...
