Embodiment 1
[0104] Example 1 Extraction process and preparation of salvia miltiorrhiza extract
[0105] Preparation of Salvia miltiorrhiza extract:
[0106] Take Danshen medicinal materials, crush them into coarse powder, add water to decoct twice, add 12 times the amount of water for the first time, add 10 times the amount of water for the first time, 2 hours each time, combine the decoction, filter, and concentrate the filtrate under reduced pressure to a relative density 1.10~1.15 (60℃) concentrate, add ethanol to 85% alcohol content, refrigerate for 24 hours, filter, the filtrate recovers ethanol until no alcohol smell, add hydrochloric acid to adjust the PH value to 2, shake with ethyl acetate Extract 3 times, combine the ethyl acetate solution, and evaporate to dryness. The residue is dissolved in acid water with pH 2 and added to the treated polyamide column, first eluted with 2 column volumes of water, discarded the washing liquid, and then eluted with 4 column volumes of 95% ethanol...
