Embodiment 1
[0024]Preparation of total lactones of custard apple seeds: take 4 kg of custard apple seeds washed and dried in advance, crush them into coarse powder, place them in a percolator with 6000 ml of 95%-98% alcohol added in advance, soak, and the time can be determined according to the outside temperature Change adjustment. Usually after 48 hours, leachate starts to be released, and about 12000ml of leachate is collected and combined. Recover the solvent under reduced pressure until there is no alcohol in the residue, cool slightly, add 1000ml of petroleum ether to dissolve and place it, and remove the precipitated brown-black massive precipitate; add 500ml of water to remove a small amount of saponin. The petroleum ether layer is concentrated and recovered to obtain the crude lactone of the custard apple seed. The crude lactone contains a large number of biogenic precursor compounds of the annona lactone without a lactone ring and a tetrahydrofuran ring structure and with very l...
Embodiment 2
[0026] The preparation of the total lactones of custard apple seeds: 4 kg of custard apple seeds washed and dried are ground into phase powder, placed in a percolator with 6000 ml of acetone-water (V / V, 90: 10) mixed solution added in advance, soaked , the time can be adjusted according to temperature changes. Usually after 48 hours, the leachate starts to be released, collect and combine about 12000ml of the leachate, recover the solvent under reduced pressure until there is no acetone, place it, remove the precipitated black lumps, add 1000ml of petroleum ether, remove the water layer, and recover under reduced pressure until there is no acetone. Petroleum ether is distilled off to obtain the crude lactone of custard apple seeds. The crude lactones were dissolved and extracted three times with 1000ml of 85% alcohol, and the alcohol layers were combined, recovered until there was no alcohol, placed and dried to obtain 148g of total lactones of the custard apple seeds.
Embodiment 3
[0028] Preparation of the effective part of anemone lactone: the total lactones of the anemone apple seed still contain a large amount of low-activity monotetrahydrofuran type anemone lactone and the secondary degradation products of anemone lactone in the plant, which must be removed. 150 g of total lactones obtained from 4 kg of raw materials in Example 1 were fully mixed with 225 g of 200-300 mesh silica gel and dried in the air; another 375 g of 200-300 mesh silica gel was dry-packed into a column, and the mixed sample silica gel was placed on the top of the column. Sequentially use the mixed solution of acetone-petroleum ether V / V (ml number): 5:95 (5000ml), 7:93 (10000ml), 10:90 (10000ml), 12:88 (10000ml), 15:85 ( 10000ml), 20:80 (5000ml), 30:70 (5000ml) elution, each receiving 1000ml. Combine the fractions (20-37) containing blatacin and scromosin under the guidance of TCL to obtain 40.5 g of the effective fraction of anemone lactone.
