Embodiment 2
[0061] Example 2, Preparation of Compound B (7-hydroxy-2', 5-dimethoxychalcane, 7-hydroxy-2', 5-dimethoxychalcane) of the present invention
[0062] 1) Separation and purification of components
[0063] ① Extraction of medicinal materials: take 15 kg of dried decoction pieces of Spatholobus Spatholobus, heat and reflux extraction with 95% ethanol with 6 times the amount (v / w) of the dried decoction pieces of Spatholobus Spatholobus for 3 times, extract for 3 hours each time, concentrate under reduced pressure after extraction, and obtain chicken S. sanguinea extract is suspended in hot water (hot water temperature not less than 50°C), extracted with ethyl acetate, and concentrated under reduced pressure to obtain the ethyl acetate extraction fraction.
[0064] ②Use silica gel column chromatography (200~300 mesh, 2.5Kg, 14×150cm) to carry out chromatographic separation of the obtained part of ethyl acetate of Spatholobus, and use different volume ratios of dichloromethane-metha...
experiment example 1
[0084] Experimental example 1, the anti-lung cancer A549 activity test of the isoflavane compound of the present invention
[0085] ① Cell inoculation
[0086] Cells in logarithmic growth phase were digested with 0.25% trypsin. Cultured in RPMI-1640 medium containing 10% FBS to form a single cell suspension. The A549 tumor cells in good condition were inoculated in a 96-well plate by counting with a cell counting plate, so that the cell density was 4×10 3 cells / mL, add 100 μL of cell suspension to each well, place at 37°C, 5% CO 2 Cultivate in the incubator for 24h.
[0087] ②, drug treatment
[0088] The sample (compound B) starts from 100 μM, and the sample is diluted with the culture medium, 2-fold dilution, and 5 drug concentrations are set, and repeated wells are tested for each concentration. Add 100 μL of drug to each well at concentrations of 100, 50, 25, 12.5 and 6.25 μM, set up 3 replicate wells for each concentration, and repeat 3 times. The negative control g...

[0093] Experimental example 2 Anti-breast cancer MDA-MB-231 activity test of isoflavane compounds of the present invention
[0094] ① Cell inoculation
[0095] Cells in logarithmic growth phase were digested with 0.25% trypsin. Cultured in DMEM cell culture medium containing 10% FBS to form a single cell suspension. The MDA-MB-231 tumor cells in good condition were inoculated in a 96-well plate by counting with a cell counting plate, so that the cell density was 4×10 3 cells / mL, add 100 μL of cell suspension to each well, place at 37°C, 5% CO 2 Cultivate in the incubator for 24h.
[0096] ②, drug treatment
[0097] The sample (compound B) starts from 100 μM, and the sample is diluted with the culture medium, 2-fold dilution, and 5 drug concentrations are set, and repeated wells are tested for each concentration. Add 100 μL of drug to each well at concentrations of 100, 50, 25, 12.5 and 6.25 μM, set up 3 replicate wells for each concentration, and repeat 3 times. The nega...
