Embodiment 1
[0016] The preparation method of a kind of novel compound in Teng chrysanthemum, comprises the following steps:
[0017] (1) Get 100kg of dried fenugreek medicinal material, add 12 times the concentration of 70% ethanol to extract three times, the time is respectively 5 hours, 3 hours, 3 hours, filter, combine the extracts, concentrate under reduced pressure until no alcohol smell, get the extract;
[0018] (2) taking the extract of step (1) and adding concentration to 20-50% ethanol for solubilization, centrifuging with a centrifuge to remove insoluble matter to obtain a supernatant;
[0019] (3) Take the supernatant obtained in step (2) and put it on a macroporous resin column, first elute 5 column volumes with 30% ethanol-water to obtain fraction 1, then elute 5 columns with 50% ethanol-water volume, concentrated, and dried to obtain Fraction 2, which was subjected to 200-300-mesh silica gel column chromatography, followed by a mixture of dichloromethane and methanol in vo...
