Examples
preparation example 1
[0028] Preparation example 1: preparation of woody oil
[0029] Take 1000g of dry woody powder, soak it with 60% ethanol at room temperature, reflux extract three times (3 × 5000ml), each extraction time is 2 hours, combine the filtrate, concentrate the filtrate under reduced pressure to a density of 1.20, add 5 times the volume of Diluted with water and extracted 3 times with ethyl acetate, combined the ester layer, concentrated under reduced pressure to recover the solvent, then put it on a silica gel column (200-300 mesh, 2000g), first washed 3 column volumes with petroleum ether, and continued to use petroleum ether-ethyl acetate Esters (20:1) were eluted for 4 column volumes, and the eluate was collected and the solvent was recovered under reduced pressure at 40°C to obtain 35 g of coyneolide, containing 32% of coynelide and 49% of dehydrocoynelide (w / w).
preparation example 2
[0030] Preparation example 2: preparation of woody oil
[0031]Take 500g of dry woody powder, soak it with 95% ethanol alcohol at room temperature, reflux extraction three times (3×3000ml), each extraction time is 2 hours, combine the filtrate, concentrate the filtrate under reduced pressure to a density of 1.20, add 5 times the volume Diluted with petroleum ether and extracted 3 times with petroleum ether, combined the ether layers, concentrated under reduced pressure to recover the solvent, and then put it on a silica gel column (200-300 mesh, 1000g), first washed 3 column volumes with petroleum ether, and continued to use petroleum ether-ethyl acetate Esters (20:1) were eluted for 4 column volumes, and the eluate was collected and the solvent was recovered under reduced pressure at 40°C to obtain 19 g of coyneolide, containing 38% of coynelide and 57% of dehydrocoynelide (w / w).
preparation example 3
[0032] Preparation example 3: preparation of woody oil emulsion
[0033] Take Preparation Example 2, 1 g of woody oil, 1.2 g of refined egg yolk phospholipid, and 0.04 g of oleic acid were added to 5.0 g of refined soybean oil, heated (50-90° C.), mixed until clear, and used as the oil phase. Disperse 2.25 g of glycerin into water for injection as the water phase. Under the condition of stirring, add the above-mentioned oil phase into the water phase dropwise to prepare a coarse emulsion, add water for injection to 100ml. The obtained coarse emulsion is further emulsified by a high-pressure homogenizer under the condition of a pressure of 100 MPa, and the pH value is adjusted to 5.0-9.0, and then sterilized after subpackaging to obtain a 10 mg / ml emulsion.
