Embodiment

[0043] Laboratory equipment

[0044] Nicolet-510P infrared spectrometer (USA), v max in cm -1 The unit is Bruker AMX-400 nuclear magnetic resonance instrument, TMS is the internal standard, the chemical shift is expressed in δ, and the coupling constant is expressed in J.

[0045] Extraction and Separation Methods

[0046] 3.4kg of ranunculus thorns were crushed, leached with 10L ethanol at room temperature, the filtrate was filtered, and concentrated under reduced pressure to obtain 6.5g of the total extract. The total extract was separated by silica gel column chromatography, and the gradient elution of the n-hexane / ethyl acetate system was followed by a mixture of n-hexane / ethyl acetate volume ratios of 10:90, 7.5:92.5 and 5:95. Solvent was eluted to obtain 8 components (F1-8), wherein, component F3 (120 mg) was subjected to repeated silica gel chromatography (1.8:8.2, v / v) in the n-hexane / ethyl acetate system to obtain 4- benzyloxylonchocarpin (new chalcone compound, 7...
