Embodiment 1
[0037] Mix pinellia and ginger evenly at a weight ratio of 1:1, add 5 to 8 times the weight of water to extract for 3 to 5 hours, filter to obtain the extract, add 3 to 5 times the weight of water to the dregs, extract for 2 to 3 hours, and combine Two extracts; add ethanol to the extract until the alcohol mass content is 60-80%, let stand for 8-12 hours, centrifuge at 4500 rpm, take the supernatant, concentrate to 1-2g crude drug·mL -1 , the concentrated solution was extracted twice with diethyl ether (the amount of diethyl ether used each time was 0.8 to 1 times the volume of the concentrated solution), to obtain an ether layer and a water layer, and the water layer was adjusted to pH 7 with NaOH. After the solution was basically clarified, anion exchange Resin adsorption, and then washed with deionized water until colorless, with 0.5 ~ 1mol L -1 The resin was eluted with NaOH solution to obtain an eluent, which was adjusted to pH 3 with HCl, concentrated to dryness under re...
