[0142] The preparation process of Erianin
[0143] Take an appropriate amount of Dendrobium officinale medicinal materials, add 10-12 times the volume of 70%-95% ethanol for reflux extraction for 1-3 hours, filter to obtain a filtrate, recover the ethanol until there is no alcohol smell, add an equal volume of ethyl acetate for extraction, The ethyl acetate was recovered to obtain an extract, and the ethyl acetate extract was separated by silica gel column chromatography, eluted with a ratio of n-hexane-ethyl acetate 3:1-5:1, and recrystallized to obtain Erianin.
[0144] Structural identification of Erianin
[0145]
