Embodiment 1
[0066] The preparation of embodiment 1 salvianolic acid L
[0067] Take Danshen decoction pieces, put them in an extractor, add 4 times the volume of medicinal materials in water (containing 0.45% sodium bicarbonate), decoct for 2 hours, filter; continue decocting medicinal residues with 3 times the volume of water for 1 hour, filter , combined filtrate, concentrated to the extract with relative density of 1.2 (80°C); adding 95% ethanol to the extract to sink to 70% (25°C), let it stand for more than 12 hours, recovered ethanol under reduced pressure, concentrated to relative density It is the extract of 1.37 (60°C).
[0068] The obtained extract was dissolved in water, passed through AB-8 macroporous adsorption resin, washed with water 12 times the volume of the column bed, and the washing solution was adjusted to pH 3.0 with hydrochloric acid. Pass the above-mentioned acidic washing solution through the AB-8 macroporous adsorption resin again, wash it with acid water with a...
