Embodiment 1
[0017] Example 1 Accurately weigh 1000g Cimicifuga, 1500g Pueraria Radix, 1000g Radix Paeoniae Rubra, and 1000g Radix Glycyrrhizae Radix Glycyrrhizae, wash and add 4.5L of 70% ethanol to soak for 4 hours, reflux extraction for 2 hours, and filter; the filter residue is reused with 4.5L of 70% Extract with ethanol under reflux for 2 hours, filter, combine the filtrates twice, let stand, filter, recover the ethanol from the filtrate to a clear paste with a relative density of 1.10 (80°C), dry under reduced pressure and vacuum, and pulverize to obtain extract A (dry powder). Store in vacuum airtight. Measured by HPLC method (dual wavelength, gradient elution): every gram of extract (dry powder) contains isoferulic acid 3.05mg (RSD 1.9%), puerarin 109.37mg (RSD 2.8%), paeoniflorin 38.61mg (RSD2 .6%).
Embodiment 2
[0018] Example 2 Accurately weigh 500g Cimicifuga, 750g Pueraria Radix, 500g Radix Paeoniae Rubra, and 500g Radix Glycyrrhiza Radix, wash and soak in 2.5L of water for 4 hours, boil for extraction for 2 hours, and filter; the filter residue is reused with 2.5L of water for extraction by boiling For 2 hours, filter, combine the filtrate twice, centrifuge, concentrate to a clear paste with a relative density of 1.16 (80°C), let cool to room temperature, add ethanol to make the alcohol content reach 80%, stir well, let stand, filter, and filtrate The ethanol is recovered and concentrated to a clear paste with a relative density of 1.16 (80° C.), dried and granulated to obtain Extract B (dry powder), which is stored in a vacuum seal. Measured by HPLC method (dual wavelength, gradient elution): every gram of extract (dry powder) contains isoferulic acid 2.09mg (RSD 1.8%), puerarin 89.91mg (RSD 2.9%), paeoniflorin 29.43mg (RSD 2.7%).
Embodiment 3
[0019] Example 3 Accurately weigh 2g of Cimicifuga, 2g of Pueraria Radix, 2g of Radix Paeoniae Rubra, and 2g of Radix Glycyrrhizae, after washing, add 100mL of 70% ethanol to soak for 4 hours, reflux extraction for 2 hours, and filter; the filter residue is reused with 4.5L of 70% ethanol Reflux extraction for 2 hours, filter, combine the two filtrates, recover ethanol to a clear paste with a relative density of 1.12 (80°C), place it to cool to room temperature, seal, and refrigerate at -20°C to obtain Extract C.
