Embodiment 1
[0079] The preparation of embodiment 1 QJSM extract
[0080] Take 2kg Cimicifuga, 2kg Ginger, 2kg Shegan, 1kg Tangerine Peel, add 10 times the amount of water, steam distillation to extract volatile oil for 3 hours, collect the volatile oil for later use; filter the filtrate, recover the solvent under reduced pressure at 60°C to a relative density of 1.20, and set aside; The filter residue was extracted twice with 50% ethanol under reflux, each time the amount of solvent was 10 times, the extraction time was 1.5 hours, filtered, the filtrates were combined, and the solvent was recovered under reduced pressure at 60°C to a relative density of 1.20; for later use, the volatile oil obtained above and The water extraction concentrate and the ethanol extraction concentrate are combined to obtain the QJSM extract.
Embodiment 2
[0081] The preparation of embodiment 2 QJSM extract
[0082] Take Cimicifuga 3kg, Ginger 3kg, Shegan 3kg, Tangerine Peel 1kg, add 20 times the amount of water, steam distillation to extract the volatile oil for 1 hour, collect the volatile oil for later use; filter the filtrate, recover the solvent under reduced pressure at 75°C to a relative density of 1.15, and set aside; Add 30% ethanol to the filter residue to reflux and extract once, the amount of solvent is 20 times, the extraction time is 2 hours, filter, combine the filtrates, recover the solvent under reduced pressure at 65°C to a relative density of 1.15, and set aside; extract the volatile oil and water obtained above The concentrated solution and the ethanol extracted concentrated solution are combined to form the QJSM extract.
Embodiment 3
[0083] The preparation of embodiment 3 QJSM extract
[0084]Take 2kg Cimicifuga, 2kg Ginger, 2kg Shegan, 1kg Tangerine Peel, add 15 times the amount of water, steam distillation to extract the volatile oil for 2 hours, collect the volatile oil for later use; filter the filtrate, recover the solvent under reduced pressure at 65°C to a relative density of 1.18, and set aside; The filter residue was extracted once with 10% ethanol under reflux, the amount of solvent was 15 times, the extraction time was 3 hours, filtered, the filtrates were combined, the solvent was recovered under reduced pressure at 60°C to a relative density of 1.18, and set aside; the volatile oil and water obtained above were extracted The concentrated solution and the ethanol extracted concentrated solution are combined to form the QJSM extract.
