Embodiment 1
[0053] (1) Take Radix Ophiopogon japonicus medicinal material, dry and grind at low temperature, use 4 times the amount of 70% ethanol to reflux extract twice, each time for 1 hour, combine the reflux liquid, recover ethanol under reduced pressure, add 4 times the amount of distilled water to suspend, and use petroleum ether Extraction, the aqueous solution is then extracted 3 times with water-saturated n-butanol, the n-butanol extract is decompressed to recover n-butanol, adsorbed on a macroporous adsorption resin, eluted with water, 20% ethanol, and 70% ethanol respectively, and collect 5 times the amount 70% ethanol eluent, recover ethanol, adsorb on alumina column, wash with water until colorless, then elute with 6 times the amount of 60% ethanol, recover ethanol from eluent, and apply water-ethanol system gradient for HPLC preparative chromatography Separation and detection, collection of 80% ethanol eluted part, namely the ophioposide D of the present invention;
