Embodiment 1

[0060] Embodiment 1: the preparation of Zijinsha extract 1

[0061] After taking 500g of Zijinsha medical material and pulverizing it, heat and reflux extraction with 80% ethanol for 2 times, each extraction for 2 hours, the amount of solvent used is 4000ml, the combined extracts are concentrated to dryness under reduced pressure to obtain 96g of ethanol extract. Weigh 10g of the ethanol extract, add 20ml of water to ultrasonically disperse, then add 100ml of cyclohexane to extract 3 times, evaporate the water layer to dryness, add 20% ethanol to dissolve it, and then put it on a HP20 macroporous resin column with a diameter-to-height ratio of 1 : 8, wash away impurities with 20% ethanol of 5 times of BV after loading the sample, then elute with 85% ethanol of 10 times of BV, collect the latter elution part, concentrate under reduced pressure to dryness, obtain the purple golden sand extract. The total content of coumarins and chromones was determined to be 61%; hydrated oxid...

Embodiment 2

[0062] Embodiment 2: the preparation of Zijinsha extract 2

[0063] Take 100g of Zijinsha medicinal material, crush it and pass it through a 20-mesh sieve, then select HA121-50-01 supercritical extraction device, use 200ml of absolute ethanol as entrainer, and extract for 3 hours at an extraction temperature of 45°C and an extraction pressure of 35MPa. The extract was evaporated to dryness under reduced pressure at 40° C. to obtain 5.2 g of supercritical extract. Weigh 5.2g of the crude extract of Zijinsha, add 10ml of water to ultrasonically disperse, then add 50ml of petroleum ether to extract 3 times, evaporate the water layer to dryness, add 30% ethanol to dissolve, and then put it on a HP20 macroporous resin column, the resin column diameter is high Ratio 1:8, wash away impurities with 5 times BV of 30% ethanol after loading the sample, then elute with 8 times BV of 80% ethanol, collect the latter eluted part, concentrate to dryness under reduced pressure, and obtain Zi...

Embodiment 3

[0064] Embodiment 3: the preparation of Zijinsha extract 3

[0065] Take 100 g of Zijinsha medicinal material and pulverize it, heat and reflux with 50% acetone to extract twice, each extraction for 1 hour, the amount of solvent used is 1000 ml, combine the extracts, concentrate to dryness under reduced pressure, and obtain 12.5 g of acetone extract. Weigh 5g of acetone extract, add 10ml of water to ultrasonically disperse, then add 60ml of ethyl acetate to extract for 3 times, concentrate the extract into a paste, add petroleum ether, let stand after ultrasonic for 30 minutes, precipitate out, filter, and use petroleum for precipitation Washed with ether and dried to obtain the extract of Zijinsha. The total content of coumarins and chromones was determined to be 52%; hydrated oxidized precurolactone, selvinol, 3'R-(+)-hexaphenol, 3'-O-acetyl The content (weight %) of holachol and isoimperatorin were 14.3%, 0.9%, 1.1%, 0.8%, 2.8%, respectively.
