Embodiment 1
[0051] Embodiment 1.1, the separation and preparation of 7-bis(4'-hydroxyphenyl)-5-hydroxyl-(2,3) epoxy-1-heptanone
[0052]Plant material: Dried stems and branches of mistletoe (Viscus coloratum (Kom.) Nakai) of the genus Mistletoe of the Morusaceae family.
[0053] Separation and preparation method: 2.0kg of stems and branches of mistletoe with leaves, reflux extraction twice with 20L of 95% ethanol, each time for 2 hours, combine the extracts, recover the ethanol and concentrate until it has no alcohol smell, add water to adjust to 4.0L, and filter with suction , the clarified liquid passes through D 101 The macroporous resin column (1.0Kg) was eluted with 4-5L of water, 20%, 40%, 75% and 95% ethanol in sequence, and 40% of the eluted fraction was collected and concentrated to dryness. The fraction eluted with 40% ethanol was repeatedly separated with Sephadex LH 20 to obtain 1,7-bis(4'-hydroxyphenyl)-5-hydroxy-(2,3)epoxy-1-heptanone. The extraction and separation flow ch...
